Summary Introduction
To review:
Functional value of the distensibility of the veins.
Introduction:
Veins are small tube like vessels, which that take blood to the heart and carry the impure or deoxygenated blood from the body tissues apart from the pulmonary vein that carries the oxygenated form of blood from the lungs back to the heart. Veins have three layers similar to that of arteries, except the outer two layers, which are much thinner. Their lumen is also wider than that of arteries.

How would you differentiate histologically the tunica media of a medium sized artery from that of the aorta? Explain in long explanation
A blood vessel with a few smooth muscle fibers and connective tissue, and only a very thin tunica externa conducts blood toward the heart. What type of vessel is this?
The main artery whose
cross-sectional area is (1 cm)
branches into 5 smaller arteries.
Each of these arteries has an
average cross-sectional area of (0.4
cm2). By what factor will the rate of
blood flow decrease when it passes
through those branches? arterial

- Several years ago the deaths of several airline travelers led to warnings about economy-class syndrome. The idea is that economy-class passengers dont have as much leg room as passengers in more expensive seats, so they are more likely to sit essentially motionless for long periods on flightsconditions that may allow blood to pool and clots to form in the legs. This condition is called deep-vein thrombosis, or DVT. Given what you know about blood flow in the veins, explain why periodically getting up and moving around in the planes cabin during a long flight may lower the risk that a clot will form.arrow_forwardIn the blood vessels, what relationship is formed between pressure, resistance, and flow?
