Week 5 Discussion Topics 1& 2
Please answer the following questions. Please write a well-developed answer for each question.

Topic # 1 What are the differences between hypoventilation and hyperventilation? What happens to oxygen and carbon dioxide levels and blood pH?

Topic #2 The death of a few airline passengers have led to worry about economy-class syndrome. The theory is that sitting motionless for long periods on flights allows blood to pool and clots to form in the legs. Low oxygen levels in airline cabins may increase clotting. If a clot becomes large enough to block blood flow or breaks free and is carried to the lungs or the brain, the outcome can be deadly.

Given what you know about blood flow in the veins, explain why periodically getting up and moving around in the airplane’s cabin during a long flight may lower your risk of clot formation.
