Under resting conditions, most of the body's blood volume is contained in: a. muscular arteries b. systemic veins c. elastic arteries d. capillaries e. venulesExplanation / Answer
6) The correct option is a. Capillaries.
Capillaries are small blood vessels. They help in the exchange of gases, nutrients, and wastes between the blood and the interstitial fluid.
7) The correct option is c. tunica media.
Tunica media is the largest layer in arteries. It maintains circulation and pressure of blood. This layer receives impulses from sympathetic vasomotor nerve fibers, and chemicals, that regulate vasoconstriction or vasodilation.
8) The correct option is e. all of the above.
An artery takes blood away from the heart to all parts of the body. The wall of artery is lined by an endothelium. In exception, pulmonary arteries carry deoxygenated blood. Tunica media of artery is made up of smooth muscle cells and elastic tissue.
9) The correct option is b. elastic arteries.
Elastic arteries are closest to the heart. They give rise to medium-sized vessels.
