Chapter 20, Problem 2CYU
Summary Introduction
To review:
The components of a muscular artery wall that enables the movement of blood within them and the mechanism that helps to maintain the movement of venous blood.
Introduction:
There are various kinds of blood vessels that are associated with the transportation of blood from various parts of the body. The different types of blood vessels present in the human body are arteries, capillaries, and veins. There exist various structural and functional differences in these three types of vessels that enable them to conduct their functions properly.

- 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_forwardExplain how constriction and dilation of muscular arteriesshunt blood from one area of the body to another andhow constriction and dilation of arterioles change bloodflow through local areasarrow_forwardBlood vessel structure and functionThe two-way exchange of substances between blood and the body occurs through what vessels?Why do the above vessels permit the diffusion of materials whereas arteries and veins do not (what is it about their structure that matches their function)?Why are valves located in veins, but not arteries?arrow_forward
