Textbook Question
Chapter 18, Problem 9CYR
Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
a. The sympathetic nervous system increases blood pressure in the short term by increasing cardiac output and peripheral resistance.
b. A sudden increase or decrease in blood pressure triggers the baroreceptor reflex, which is mediated by the medulla and the autonomic nervous system.
c. Hormones that decrease blood volume and blood pressure include antidiuretic hormone and aldosterone.
d. Angiotensin-II is a chemical that produces profound vasoconstriction.
e. The kidneys control blood pressure directly through adjustment of blood volume.
