Exam 30: Circulation of the Blood

Name and explain the vasomotor reflexes.

Which of the following tasks must the circulation control mechanism accomplish?

The Latin word lamina means:

Bleeding that occurs at a relatively slow, steady rate would indicate that the damaged blood vessel is most likely a vein.

Osmotic pressure tends to move plasma out of the capillary and into the tissues.

Name and give the location of five places in the body where a pulse can be felt.

Local vasodilation or reactive hyperemia can be caused by the release of endothelin by the blood vessels.

All of the following will increase heart rate except:

Name and explain the relationship among the variables that impact the minute volume of blood.

Operation of the Starling law ensures that when the amount of blood returned to the heart is increased, stroke volume automatically increases to pump it out.

By the time the blood reaches the venous end of the capillaries, the pressure on the blood has reached 0 mm Hg.

Because of the high concentration of protein in plasma, a decrease in the red blood cell count will cause an increase in blood viscosity.

The volume of blood circulated per minute is equal to the difference between the mean arterial pressure and the central venous pressure, divided by the resistance.

To stop arterial bleeding, pressure must be applied between the damaged artery and the heart.

What are two functions that circulation control mechanisms must accomplish?

An increase in arterial blood pressure causes an increase in parasympathetic impulses to the heart and blood vessels.

A collection of mechanisms that influence the circulation of the blood is the definition for:

The blood in the subclavian vein of the chest had a P1 of 15 mm Hg. For the blood to flow back to the heart, the P2 in the superior vena cava:

Which of the following arteries is not one of the six major pressure points used to stop arterial bleeding?

Which of the following is not a true statement about cardiac output?
