Summary Introduction
To explain:
The reason for which some people feel light headed after donating blood.
Introduction:
The donation of blood decreases the volume of the blood in the body. The body has to maintain homeostasis and detect the change in the blood volume. For the body, the blood donation is equivalent to a controlled hemorrhage.

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.

Part1
1) How would the BP of an anxious patient visiting a doctor be different than if the patient is calm?
2) In atherosclerosis, plaque builds up inside the arteries. How would this affect BP? Is this an example of hypertension or hypotension?
Part 2:
The circulatory system has 5 functions.
· Highlight the statements below that are only functions of the circulatory system.
It carries cells that help to fight diseases.
It gives structure and support to the body.
It carries waste products to the urinary system.
It carries carbon dioxide from cells to the lungs.
It maintains body posture.
It carries nutrients from the digestive system to other cells.
It carries oxygen from the lungs to other cells.
· The list gives some structures in the blood and circulatory system.
Heart, artery, red blood cell, ventricle, capillary, plasma, vein, white blood…
Women in the late nineteenth and early twentieth centuries wore whalebone corsets that severely restricted the respiratory and digestive systems. These corsets were worn to have a wasp-like waist. It was quite common for these women to faint—in fact, they had “fainting couches.” Explain the physiological reason for their fainting problems.

- 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_forwardWe typically hear about how deadly hypertension is, but the body has much more mechanisms for raising blood pressure than for lowering it.
