Artery : Structure of an artery - role of an artery in the human body


 What Is Artery?

The nearest thing to the human body's highway system is the arterial system. Its primary purpose is to take oxygen-rich blood from the heart to the body's tissues.  The system is made up of a series of arteries that branch into smaller vessels, called arterioles that lead to the capillaries. The capillaries are tiny, thin-walled vessels that deliver blood directly to the body's cells.

What Is Artery

The aorta is the largest artery in the human body. It is about the size of a garden hose and carries oxygen-rich blood from the heart to all of the body's tissues. The aorta begins at the heart's left ventricle—the chamber that pumps blood out of the heart—and extends down to the abdomen, where it branches off into smaller arteries. The aorta has three layers: an inner layer of smooth muscle and connective tissue, a middle layer of smooth muscle, and an outer layer of connective tissue.

Structure of an artery in the human body

Arteries are the blood vessels that carry oxygenated blood away from the heart to the different tissues of the body. The structure of an artery is composed of three layers: the intima, the media, and the adventitia. The intima is the innermost layer and is made up of a smooth endothelium. The media is the middle layer and is composed of smooth muscle cells.

The structure of an artery in the human body is fascinating. The aorta, for example, is the largest artery in the body. It is about the size of a garden hose and carries blood from the heart to the rest of the body. The aorta is made up of three layers: the inner layer, the middle layer, and the outer layer.

Your arteries begin branching out from your aorta, which gets blood out of your coronary heart. From there, arteries continue to branch out into smaller and smaller vessels going at some point of your frame.

Arteries appear to be tubes. They have thicker and more muscular walls than veins to be able to take care of the force of blood coming out of your coronary heart’s left ventricle. Think of them like your furnace ducts (but flexible) that take heat air at some stage in your own home when your furnace is going for walks.

Your aorta, your largest artery, is set 10 millimeters (mm) to 25 mm (.4 inch to .9 inch) in diameter. Other arteries may be 3 mm to 5 mm (.11 inches to .19 inches) in diameter, at the same time as the smallest arteries, arterioles, can be .30 mm to .01 mm in diameter.

Your arteries have three layers:

  • Tunica intima, or inner layer: Has tissue with elastic fiber.

  • Tunica media, or center layer: This is in most cases smooth muscle that lets your arteries get tighter or more open as wanted.

  • Tunica externa, or outer layer: Interacts with different tissues, inclusive of nerves that ship instructions to tug in or enlarge.

The two kinds of arteries are:

Elastic: Have greater elastic tissue than muscular arteries and are positioned close to your coronary heart. Examples: Aorta and pulmonary artery.

Muscular: Have more easy muscle than elastic arteries. Examples: Femoral, radial and brachial arteries.

What is the role of an artery in the human body?

Arteries act as conduits for blood flow and carry oxygen and nutrients to your tissues. They are situated in the walls of major blood vessels and deliver blood to smaller arteries and veins. Arteries play an important role in the human body by delivering oxygen and nutrients to your tissues..

Specific arteries offer blood to organs or positive components of your frame, along with:

  • Coronary arteries: Heart.

  • Carotid arteries: Brain, head, face and neck.

  • Vertebral arteries: Brain and spine.

  • Iliac arteries: Pelvis.

  • Femoral artery: Legs.

  • Subclavian arteries: Head, neck and palms.

  • Celiac and mesenteric arteries: Digestive gadget.

What affects the health of an artery?

The purpose of this document is to introduce readers to the health effects of artery plaque. Plaque is a build-up of fat, cholesterol, and other substances inside the walls of your arteries. Over time, plaque can cause an artery to narrow, which can lead to heart disease or stroke.

Conditions which can damage your arteries consist of:

  • Atherosclerosis.

  • Aneurysm (a stretch or bulge in an artery that may destroy open).

  • Blood clot.

  • Coronary artery disorder (atherosclerosis to your coronary arteries).

  • Carotid artery disorder (atherosclerosis to your carotid artery).

  • High blood strain.

  • High cholesterol.

  • Peripheral artery sickness (PAD).

  • Vasculitis.

Artery symptoms

Artery symptoms can often be difficult to diagnose, as they can be accompanied by a variety of other symptoms.

Artery symptoms can include: * Sudden chest pain * Persistent shortness of breath * Sweating * Yawning * Headache * Nausea or vomiting * Extreme lightheadedness The symptoms of an artery problem can vary a lot. Some people only experience one or two of the symptoms. Other people may have every symptom mentioned. There is not one specific symptom that signals that an artery is damaged.

Symptoms of artery situations include:

  • Chest ache.

  • Heart attack.

  • Stroke.

  • Numbness or pain on your arms and legs.

  • Shortness of breath.

  • Belly ache.

  • Tiredness.

Maintain artery health

  1. For many people, maintaining their artery health is a top priority. This is important for a number of reasons. First, keeping your arteries healthy can help to prevent heart disease. This is a condition that can lead to a number of serious health problems, including heart attacks and strokes.

  2. High cholesterol is a condition where there are too many lipids, or fats, in the blood. This can cause medical problems, including heart disease. To prevent problems, people with high cholesterol often need to make lifestyle changes and take medication.

  3. Aortic aneurysms happen when the walls of the aorta, the main artery in your body, weaken and start to bulge out. Aortic aneurysms can lead to life-threatening bleeding. Keeping your arteries healthy is important to preventing aortic aneurysms. The best way to keep your arteries healthy is to eat a healthy diet, exercise regularly, and not smoke.

  4. A healthy diet and a healthy lifestyle are the best ways to maintain good cardiovascular health. This means eating a diet that is low in saturated and trans fats, and high in fruits, vegetables, and whole grains. It also means getting regular exercise, and maintaining a healthy weight.

Things you do to maintain your coronary heart wholesome may even help your arteries. You can:

  • Eat a healthful food regimen that doesn’t encompass trans fat or saturated fats.

  • Get regular workout.

  • Avoid tobacco merchandise.

  • Get seven to nine hours of sleep each night time (for adults).

  • Cope well with stress.

  • Get treatment for high blood strain, excessive cholesterol and diabetes.

  • Stay at a wholesome weight.

  • Limit how much alcohol you drink.
