Chapter 41, Problem 2CCQ
Summary Introduction
To write:
The reason some people faint after donating blood and prevention from fainting.
Introduction:
Blood volume and blood pressure are closely related to each other. If there is a change in blood volume, the arterial pressure is affected as the cardiac output is changed. If there is an increase in blood volume, the central venous pressure also increases.

Doctors strongly recommend that travelers on long airline flights stretch their legs or stand up and walk down the aisle periodically in order to prevent development of a clot in their lower legs. This is a condition known as Deep Vein Thrombosis (DVT). Explain why this condition is more likely to occur in someone who is sitting still for long periods of time such as on an airplane.
Several years ago, the deaths of several airline travelers led to the warning about “economic-class syndrome.” The idea is that economic-class passengers do not have as much leg room as passengers in more expensive seats, so they are more likely to sit essentially motionless for long periods of flights-conditions 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 a plane’s cabin during a long flight may lower the risk that a cloth will form.
A patient has had a serious accident and lost a lot of blood. In an attempt to replenish body fluids, a large amount of distilled water was transferred directly into one of his veins. What will be the most probable result of this transfusion?
