BIOE 322/BIOS 332 Fundamentals of Systems Physiology Spring 2008 Problem Set #1 Solutions 1. Q1. The normal response to a decrease in blood pressure is for receptors in the wall of a blood vessel to detect the decrease and for the brain to stimulate the heart to contract faster, which increases blood pressure and maintains homeostasis. (Lecture 1) Q2. Just before Molly fainted, her heart rate increased. However, it did not increase enough to accommodate her change in position, and her blood pressure dropped below normal. The decreased blood pressure resulted in the delivery of less blood to the brain, homeostasis of brain tissue was disrupted, and Molly fainted. Q3. When Molly fell to the floor, she returned to a lying down position. This eliminated the pooling effect of the blood in her veins below the heart because of gravity. Therefore, blood return to the heart increased, blood pressure increased, blood flow to the brain increased, homeostasis of brain tissue was restored, and she regained consciousness. 2.
