Chapter 11, Problem 49CT
Summary Introduction
To analyze:
Mrs. Rees is brought to the emergency room after an auto accident. She has a rapid pulse even after hemorrhaging. Her blood pressure is within the normal range even after the blood loss. The compensatory mechanisms that maintain the blood pressure of patient after blood loss.
Introduction:
The sympathetic nervous system maintains blood pressure by increasing vasoconstriction. This is narrowing of the blood vessels, which leads to an increase in the blood pressure. Sympathetic center in the brain induces vasoconstriction to regulate blood pressure in different situations.

Mr. Adams is taking an ACE inhibitor and an angiotensinreceptor blocker, both drugs that block the RAAS, for his high blood pressure. He complains that when he tries to engage in physical activity, he feels faint. He is asked to exercise on a treadmill, and his blood pressure remains very low when he exercises, rather than rising with his level of physical activity. Explain how his medications could be causing his current problem?

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.
