An elastic artery (conducting artery or conduit artery) is an artery with many collagen and elastin
Elastin
Elastin is a highly elastic protein in connective tissue and allows many tissues in the body to resume their shape after stretching or contracting. Elastin helps skin to return to its original position when it is poked or pinched. Elastin is also an important load-bearing tissue in the bodies of ver…
filaments in the tunica media, which gives it the ability to stretch in response to each pulse.
Elastic arteries are thick-walled arteries near the heart. These arteries are the largest in diameter. Elastic arteries act as pressure reservoirs; they expand and contract as blood is ejected from the heart. Continuous capillaries are the most common capillaries in the body.
An elastic artery ( conducting artery or conduit artery) is an artery with many collagen and elastin filaments in the tunica media, which gives it the ability to stretch in response to each pulse. This elasticity also gives rise to the Windkessel effect, which helps to maintain a relatively constant pressure in the arteries despite ...
Which artery has many collagen and elastin filaments in the tunica media?
Elastic artery. An elastic artery ( conducting artery or conduit artery) is an artery with many collagen and elastin filaments in the tunica media, which gives it the ability to stretch in response to each pulse.
Which arteries are elastic?
They give rise to medium-sized vessels known as distributing arteries (or muscular arteries ). The pulmonary arteries, the aorta, and its branches together comprise the body's system of elastic arteries.
How does skeletal muscle perfusion work?
Skeletal muscle perfusion varies drastically and is determined by how active the muscle is. After a large meal for example, blood flow is reduced to the muscles by around 90% which redirects blood flow to the digestive tract to absorbs nutrients from digestion.
Which type of cell is held together by tight junctions?
Continuous Capillaries: Occur in most tissue (i.e. skeletal muscle) and are the most common. The endothelial cells are held together by tight junctions. Contain intercellular clefts so small solutes such as glucose can pass through but plasma proteins, large molecules, and platelets and blood cells are held back.

Elastic arteries contain larger numbers of collagen and elastin filaments in their tunica media than muscular arteries do, giving them the ability to stretch in response to each pulse. Elastic arteries include the largest arteries in the body, those closest to the heart, and give rise to the smaller muscular arteries.

An elastic artery (conducting artery or conduit artery) is an artery with many collagen and elastin filaments in the tunica media, which gives it the ability to stretch in response to each pulse. This elasticity also gives rise to the Windkessel effect , which helps to maintain a relatively constant pressure in the arteries despite the pulsating nature of the blood flow.

Elastic fibers are extensive in the tunica media of the aorta and dampen the pulse pressure generated by the heart. Smooth muscle is relatively thin in the aorta to increase lumen size and systemic blood flow. The aorta's tunica media is thick with dense regular connective tissue to withstand the blood's pressure.
