Question 2

Compare the structure and function of arteries to that of veins.

Accepted Answer

Arteries are blood vessels that transport blood away from the heart.With the exception of the pulmonary artery,they carry oxygenated blooD They have three layers: the innermost is a thin layer called the endothelium,the middle is a thick layer of smooth muscle and elastic tissue,the outer layer is connective tissuE The elastic tissue enables it to withstand the pressure of the blood flow.
Veins are blood vessels that transport blood to the heart.With the exception of the pulmonary vein,they carry deoxygenated blooD They have three layers in their walls as well.The main difference is that there is less smooth muscle in the middle layer and less connective tissue in the outer layer.The wall of a vein is thinner than that of an artery.
