Exam 30: Circulation of the Blood

Circulatory shock caused by a drop in the amount of blood in the circulatory system is called _____ shock.

The stress-relaxation effect occurs in all blood vessels but is most important in the arteries.

Cardiac output and peripheral resistance are directly proportional to arterial blood volume.

Peripheral resistance is affected primarily by:

The pulse in the wrist is felt over which artery?

If the stroke volume remains constant, parasympathetic stimulation of the heart will cause an increase in cardiac output.

The primary fluid flow principle of circulation is based on all of the following except a fluid:

Which of the following factors would cause fluid to leave the blood vessel at the arterial end of the capillary?

Name and explain the reflexes that affect heart rate.

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

Explain the role of the lymphatic system in maintaining blood volume.

If the heart rate drops and the stroke volume increases, cardiac output will always show a decrease.

An increase in aldosterone would cause an increase in blood volume.

If resistance in the blood vessels remains constant, the minute volume of blood is directly related to the difference between arterial and venous pressure.

The "pump" of the "respiratory pump" that moves blood to the central veins is the diaphragm.

Hypoxic conditions act as the major stimulant to chemoreceptors.

Circulatory shock caused by the effects of infectious agents is called _____ shock.

Which of the following statements is not true of the cardiovascular system?

Pulse is defined as the alternate expansion and recoil of an artery.

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.
