Describe how blood pressure is regulated
What will be an ideal response?
Mean arterial pressure is the driving force that moves blood through the arterial system and is controlled by a variety of factors that influence cardiac output, total peripheral resistance, and blood volume. Factors that influence cardiac output include heart rate, stroke volume, autonomic activity, and venous return. Factors that influence peripheral resistance include arteriole diameter and blood viscosity. Blood volume is controlled by kidney function, hormones, bulk flow mechanisms, and salt/water balance. It is important to note that many of these factors overlap. For example, blood volume influences venous return, and arteriole radius is influenced by some of the same hormones that influence water and salt balance.
