Mаintаining hоmeоstаsis requires careful regulatiоn of both blood flow and air flow to meet the body’s changing demands during activities such as sleeping, eating, or exercising. At a fundamental level, fluid and air move down pressure gradients, and the body can regulate this movement by changing resistance within vessels or airways. Use these principles to answer the following questions: a. In the cardiovascular system, where is pressure highest and where is it lowest? b. Which component of the cardiovascular system is primarily responsible for generating this pressure gradient? Explain your answer. c. By which processes does the autonomic nervous system (ANS) increase or decrease blood flow to a specific tissue? In your answer, explain how this process is related to vascular resistance.
