Which of the following statements is correct?

Select one:

a. Total peripheral resistance is directly proportional to venous return

b. Total peripheral resistance is directly proportional to cardiac output

c. Mean arterial pressure is inversely proportional to total peripheral resistance

d. Mean arterial pressure is directly proportional to blood vessel diameter

Homework Answers

Answer #1

a. Total peripheral resistance is directly proportional to venous return ---> FALSE (more venous return indicates less total peripheral resistance)

b. Total peripheral resistance is directly proportional to cardiac output --> TRUE (more cardiac output means, more peripheral resistance)

c. Mean arterial pressure is inversely proportional to total peripheral resistance ---> FALSE - MAP is directly proportional to total peripheral resistance

d. Mean arterial pressure is directly proportional to blood vessel diameter ---> FALSE - MAP is inversely proportional to diameter of a blood vessel

The flow rate (F) of blood through a blood vessel describes the volume of blood that passes through the vessel per a unit of time. Flow rate is affected by physical variables like the resistance of the blood vessel (R) and the pressure gradient within the blood vessel (∆P). Which one of the following statements correctly summarizes the relationships between these variables? *Hint: F = ∆P/R Select one: a) Flow rate is equivalent to the pressure gradient multiplied by the...
