Exam 30: Circulation of the Blood

Blood viscosity is highly variable in healthy individuals under resting conditions.

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

An increase in blood temperature tends to slow down heart rate.

Blood viscosity is caused by both red blood cells and the protein concentration of the blood.

The capillaries perform the transport function of the circulatory system.

The effect of what substance is to increase the total blood volume?

The Fick formula is used for determining:

The pulse in the neck is felt over which artery?

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

When you take a blood pressure reading, the first sound that you hear (top reading) is the:

Explain how the Starling law relates to cardiac output.

The pressure gradient in the ventricles exceeds the pressure in the pulmonary artery and aorta.

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.

The greater the cross-sectional area of a vessel, the greater the speed of the blood flow.

Circulatory shock caused by an acute allergic reaction is called _____ shock.

Which of the following is not true of the baroreceptors?

In a typical healthy heart, ejection fraction is between 80% and 85%.

If a pulse were taken at the popliteal and dorsalis pedis arteries at the same time, it would be felt at the popliteal artery first.

Peripheral resistance is affected primarily by:

A fluid flows because a pressure gradient exists between different parts of its volume.
