Exam 30: Circulation of the Blood

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

Diastolic pressure is the force of blood pushing against artery walls when the ventricles are contracting.

The pulse in the wrist is felt over which artery?

A decrease in total plasma volume results from the _____ mechanism.

Which of the following is not a means by which venous blood is returned to the heart?

Explain the primary principle of circulation as related to Newton's first and second laws of motion.

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

The right atrium would have the lowest blood pressure in the systemic circulatory system.

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

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

An increase in ADH in the blood would have a tendency to increase total blood volume.

Vasomotor control mechanisms influence:

The cardiac output of the left ventricle is greater than the cardiac output of the right ventricle.

The vasomotor control mechanism regulates changes in the diameter of arteries.

When the amount of blood reaching the medulla drops, the medulla stimulates vasodilation to increase the flow of blood to the brain.

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

Hypoxic conditions act as the major stimulant to chemoreceptors.

ADH is short for antidiuretic hormone.

Acetylcholine can increase the strength of contractions and therefore increase ejection fraction.

Cardiac output is determined by multiplying stroke volume and heart rate.
