What are Arteries?

Arteries are blood vessels that transport oxygen-rich blood throughout the body. They must move waste and fluid from the tissues to the circulatory system. Atherosclerosis can cause several disorders, including heart disease and stroke. You should consult a doctor as soon as possible if you have any symptoms, such as chest discomfort, shortness of breath, or a sudden change in your blood pressure. Because there are several therapies for arterial disorders, receiving the correct aid as soon as feasible is critical for your long-term health and well-being.

Arteries: Diseases

A disorder that affects the arteries is known as arterial disease. Arteries transport blood from the heart to all of your organs. Diseases can cause artery damage, resulting in decreased blood flow and possibly organ failure. Always seek medical attention if you are experiencing chest pain or difficulty breathing! Knowing the fundamentals of arteries and arterial illnesses can enable you to make better-educated health decisions. This article will go through the many forms of artery illnesses, their symptoms, and the available therapies. Remember that arterial diseases are severe and should not be taken lightly. If you or a loved one suffers signs of an arterial illness, please get expert assistance immediately!

Types Of Arteries

There are three types of arteries within our body:

  • 1. Elastic Arteries: These arteries are more pliable than muscle tissue. The enhanced flexibility allows them to tolerate blood surges. Elastic arteries, like the aorta and pulmonary artery, exit the heart.
  • 2. Muscular Arteries: These arteries have smoother and less elastin muscle fiber. Elastic arteries pass into muscular arteries. Moreover, the smooth muscle fibers enable them to expand and contract to regulate blood circulation. The femoral and coronary arteries are two instances of these arteries.
  • 3. Arterioles: Arteries branch out into smaller channels called arterioles. It helps transport blood via microscopic circuits of capillaries.

Tests of the Arteries

Arteries are essential for delivering oxygen and nutrients to your cells and removing waste products from your body. If a disease or injury damages arteries, the blood flow can become blocked or inflamed, leading to many diseases and injuries. Healthcare providers typically perform tests on the arteries to prevent or treat these conditions. Some of the basic tests of arteries are as follows:

1. Angiogram (angiography)

A thin, flexible tube is placed into the arteries, a specific dye is administered, and blood circulation through the arteries is seen using an X-ray. Angiography is frequently used to identify areas of artery constriction or bleeding.

2. CT-A scan (Computed tomographic angiography)

A CT scanner collects several X-rays, which are then compiled by a computer into detailed pictures of the arteries. This scan may typically detect artery constriction or other abnormalities with less risk than traditional angiography.

3. Cardiac catheterization

A catheter is a thin and flexible tube. It is placed into a groyne, arm, or neck artery and progresses into the heart. A contrast enhancement dye is administered using the catheter, allowing blood circulation through the coronary artery to be observed on an X-ray screen. Atherosclerosis in the arteries can then be diagnosed and treated.

4. Artery Biopsy

A tiny portion of an artery is taken and inspected under a microscope to detect vasculitis. The temporal artery within the scalp is the most commonly biopsied artery.

5. MRA scan (Magnetic resonance angiography)

An MRI scanner creates very detailed pictures of components within the body using a computer and a powerful magnet. MRA is a configuration that enables an MRI scanner to exhibit pictures of the arteries in the most effective manner possible.

6. Stress Test

The heart is encouraged to beat quickly by exercise or medication. As the heart’s blood circulation rises as a result of the stress, narrowing inside the coronary artery can be detected using various testing procedures.

Treatments for the Arteries

Arteries are a vital part of the body and must be treated carefully to remain healthy. Many treatments are available, so you must speak with your doctor about what would be best for you. If you have any symptoms, such as chest pain or shortness of breath, seek help immediately! Depending on the type of artery disease, different treatments may be necessary. Following are the different types of arteries treatments to check out.


In complement to its anti-inflammatory and fever-reducing effects, aspirin inhibits blood coagulation. Aspirin, when used daily, can help avoid heart strokes and attacks.


Anti-inflammatory medications such as methylprednisolone or prednisone are prescribed to treat artery vasculitis.

Arterial stenting

A stent, a tiny mesh tube, is inserted into an artery to keep it open. The coronary artery is the most often stented.

Plavix (clopidogrel)

A medication that, like aspirin, inhibits blood coagulation. Plavix is routinely recommended to avoid future strokes or heart attacks.

Cilostazol and pentoxifylline

Medication that aids in increasing blood flow via the arteries inside the legs. These medications help alleviate the discomfort of walking in persons with peripheral arterial disease.


During an arterial catheterization, an inflated balloon is placed within the artery to assist loosen it up.


Oral cholesterol-lowering medications include atorvastatin, lovastatin, fluvastatin, pravastatin, pitavastatin, rosuvastatin, and simvastatin. Statins, when taken daily, can reduce the risk of having a stroke or a heart attack.


Tocilizumab (Actemra), a biologic medication, may be utilized. Tocilizumab is administered through subcutaneous injection. This medication may be used with steroids. Thrombolytics: Strong “clot-busting” medications can be injected into the bloodstream to destroy a blood clot that has caused a stroke or a heart attack.

What are Arteries and Veins?

Arteries and veins are two of the body’s most significant blood vessels. They transport blood to all body regions and aid in heart function. Diseases and treatments can cause artery and vein damage, resulting in diminished heart function or even death. Surgery, embolization (a technique that plugs a vessel), angioplasty (in which a balloon is placed into an artery to expand it), and stents are all treatment possibilities. Understanding the description, function, illnesses, and treatments of arteries and veins is critical for maintaining a healthy heart and may help you better comprehend the importance of blood flow.

Coronary Artery Disease

Coronary artery disease (CAD) is a disorder that causes plaque accumulation in the arteries, leading to heart attacks and strokes. If left untreated, CAD can swiftly progress to death from heart disease. The good news is that medications are available to help lessen or perhaps prevent these diseases from occurring. Knowing the symptoms and indicators of CAD is critical for early identification and treatment. Chest discomfort, shortness of breath, exhaustion, and an abrupt heart rate shift are among the most prevalent indications and symptoms of coronary artery disease.

If you have any of these symptoms, you should consult a physician as soon as possible. Medication, angioplasty (a technique that opens clogged arteries), and coronary artery bypass surgery are among the therapies available to help minimize the chance of a heart attack and stroke. So, whichever your heart health priorities are, be on the lookout for symptoms and signs of coronary artery disease. Coronary artery disease symptoms include:

  • 1. Chest discomfort
  • 2. Dizziness
  • 3. Sweating coldly
  • 4. Weakness

Peripheral Artery Disease

The disorder known as peripheral artery disease (PAD) affects the arteries that lead away from the heart. It can reduce blood flow to your extremities, such as your legs and feet. If you are at risk for PAD, be examined periodically and take care of your general health to avoid this dangerous illness. PAD can be treated with medications or surgery, but it is frequently deadly if not addressed early. If you detect any PAD symptoms, such as a reduction in blood flow, discomfort, or swelling in your leg or foot, immediately consult a doctor. Peripheral artery disease symptoms include:

  • 1. Discomfort in the hips or legs 
  • 2. Leg fatigue
  • 3. Difficulty walking or stair climbing
  • 4. Foot or lower leg sores that don’t cure

How are Arteries Different from Veins?

The point of differences that makes arteries distinct from veins are mentioned below:


  • 1. Remove oxygen-rich blood from the heart and circulate it throughout the body.
  • 2. Have robust, muscular walls which can withstand the tremendous pressure of blood pumped out by your heart with each beating.
  • 3. Valve replacement is unnecessary since the power of the blood flowing from your heart guarantees that the blood only flows in a single direction.


  • 1. Deliver blood back to the heart when the body’s tissues and cells have depleted it of oxygen. This is referred to as oxygen-depleted blood or deoxygenated blood.
  • 2. Since the pressure within veins isn’t as high as in arteries, their walls are thinner. 
  • 3. They have valves within to prevent blood from flowing incorrectly.

Where are Arteries Located?

Some of the arteries inside the body’s system are mentioned below:

The aorta

The aorta is the largest artery, measuring roughly an inch broad. The aortic valve allows blood to flow through the heart and the aorta. From there, other arteries split off.

Head and neck arteries

The left and right common carotid artery, which are positioned in the neck, are two such examples. The internal and external carotid artery arise from common carotid arteries. The internal carotid artery transports blood into the brain. The external carotid artery is responsible for transporting blood to the lower face and neck.

Abdomen arteries

The celiac trunk, which provides blood to the spleen, liver, and stomach, is one type. The inferior and superior mesenteric arteries carry blood to the pancreas and intestines.

The inferior phrenic artery is responsible for transporting blood towards the diaphragm. The renal arteries also transport blood toward the kidneys. The lumbar arteries supply oxygen and nutrients to the vertebrae and spinal cord.

Arm arteries

The axillary artery, which runs from the thorax to the arms, is an example of an arm artery. The brachial artery transports blood towards the upper arm. Blood is carried to the wrist and hand through the ulnar and radial arteries.

Torso arteries

The bronchial artery that provides blood to the lungs is an example. Another pericardial artery transports blood to the heart’s membrane.

The superior and posterior intercostal arteries are two pairs of arteries on both sides of the human body that transport blood to various parts of the torso, including the back, skin, and spinal cord.

Leg arteries

The femoral arteries that supply blood to the thigh are among the leg arteries. The popliteal artery transports blood underneath the knee. The tibial arteries provide blood circulation to the foot and ankles.

What do arteries look like?

Arteries resemble tubes that transport blood throughout the body. They are color-coded by illness to make identification and treatment simpler. Furthermore, they have stronger and more muscular walls than veins, allowing them to withstand the force of blood flowing from your heart’s left ventricle. Consider them flexible furnace ducts that distribute warm air around your home while your furnace is on.

What are the common conditions and disorders that affect arteries?

Arteries are important blood veins that transport blood throughout the body. They can burst, impede blood flow, or become sick due to several illnesses and ailments. Certain common conditions and disorders that affect arteries are mentioned below.

Amaurosis fugax

A transient decrease in blood circulation to the retina, the light-sensitive tissue which covers the rear of the eye, causes visual loss in one eye. It generally happens when a piece of cholesterol plaque bursts into one of the carotid arteries and goes to the retina artery.

Peripheral artery disease

Atherosclerosis is a condition that causes artery constriction in the groyne or legs. A decreased blood circulation to the legs can result in discomfort or poor wound healing.


The accumulation of cholesterol in the artery walls as plaques. Heart problems and strokes can be caused by atherosclerosis in the arteries of the brain, the heart, or the neck.

Arterial thrombosis

A blood clot forms unexpectedly in one of the arteries, cutting off blood circulation. To re-establish blood circulation in the artery, prompt therapy is required.

Myocardial infarction

A blood clot forms unexpectedly within one of the arteries providing blood to the heart.

Cerebrovascular mishap

A blood clot forms unexpectedly within one of the arteries delivering blood to the brain. Strokes can also happen when one of the brain’s arteries breaks, resulting in bleeding.

Carotid artery disease

Atherosclerosis is characterized by narrowing either one or both carotid arteries in the neck. Stroke is made more likely by carotid artery disease.

Vasculitis (arteritis)

Swelling of the arteries can affect one or many arteries at once. The most common cause of vasculitis is an excessive immune system.

Stenosis of the arteries

Atherosclerosis is the most common cause of artery narrowing. When stenosis arises in the arteries of the neck, heart, or legs, the reduced flow of blood can result in significant health concerns.

Common signs or symptoms of artery conditions

Arteries are an essential element of the body that performs several vital activities. However, they can be impacted by several illnesses, some of which can be fatal. It is critical to get medical attention if you see any indications or symptoms of an arterial issue. Some of the common signs and indications of artery conditions are:

  • 1. Heart disease
  • 2. Stroke
  • 3. Chest pain
  • 4. Shortness of breath
  • 5. Belly pain
  • 6. Tiredness and fatigue

Treatment options for arterial issues differ based on the condition and age of the patient. However, one thing is sure: it is essential to be educated on artery diseases so that you may take the necessary precautions to preserve your health.


You have just learned everything you need to know about arteries. However, it is insufficient to understand what they do and how they connect to various health issues. This is why doctors advise patients exposed to risk factors that might lead to blockages to undergo frequent check-ups. Maintain a healthy lifestyle and monitor your cholesterol levels to avoid such scenarios. Also, learn about the many forms of artery illnesses so you can take preventative steps if necessary.
