What is the advantage of arterial wall being thick strong and elastic?

Since they must receive the blood directly from the heart which pumps the blood at a pressure sufficient to enable circulation, they need thick and elastic walls to both sustain the pressure (and so keep the blood flowing) and to withstand the pressure (and not get affected by the pressure).

Why do the walls of arteries need to be thick and elastic?

Arteries have thick muscular walls to resist bursting under the high pressure of blood passing through them. Large arteries near the heart also have a lot of elastic fibers, so they may expand and contract in response to the pulse pressure.

Why are the artery walls thick?

Arterial walls thicken both as a result of deposition of cholesterol and atherosclerotic plaque and in response to wall stress, as in hypertension. Ultrasonography can detect arterial wall thickening, and the carotid arteries are easily accessible.

Why are arterial walls thicker than veins?

Arteries and veins experience differences in the pressure of blood flow. … Arteries experience a pressure wave as blood is pumped from the heart. This can be felt as a “pulse.” Because of this pressure the walls of arteries are much thicker than those of veins.

Why do arteries need to be strong?

Arteries carry the blood away from the heart towards different parts of our body , the blood if forcefully pumped into the arteries by the heart , naturally it must have strong walls so as to protect it from getting ruptured.

What is artery thickening?

Atherosclerosis is thickening of the walls of the arteries. It is also known as hardening of the arteries. It is caused by a buildup of plaque in the inner lining of an artery. Risk factors may include high cholesterol levels, high blood pressure, smoking, diabetes, obesity, and saturated fats.

What are elastic arteries?

Elastic arteries are those nearest the heart (aorta and pulmonary arteries) that contain much more elastic tissue in the tunica media than muscular arteries. This feature of the elastic arteries allows them to maintain a relatively constant pressure gradient despite the constant pumping action of the heart. Arterioles.

Why do arteries have thick walls as compared to veins class 10?

As arteries carry blood from heart to all parts of the body, they have thick and elastic walls as they are under high pressure. … They withstand the pressure that has thick walls whereas veins have low pressure.

Why do arteries need to be thick muscular and elastic quizlet?

The walls of arteries need to be thick with a lot of elastic tissue because blood travels through them with high pressure. They stretch and reset as pressure changes.

Why do arteries in the human circulatory system have thick strong walls?

Ans: The wall of the arteries is made up of elastic cells and muscular cells. The thickness is provided by these cells so that the arteries can withstand the pressure of blood flow from the heart. Also, the arteries maintain a significant pressure drop to allow the flow to reach extreme portions of the body.

What do elastic walls do?

The elastic wall of arteries helps to maintain a pressure gradient that drives the blood through the arterial system.
