The semilunar valves open during which part of the cardiac cycle?

This component of the cardiac conduction system passes the electrical impulses from the atria to the ventricles.

Angiotensin II will cause

As blood passes through the systemic circulation, which is true?

These vessels function in the exchange of substances.

When blood pressure rises, cardiac output is

ANP is produced by cells in the

True or False: ADH lowers blood pressure

Hormone released by the kidneys to stimulate red blood cell production and vasoconstriction

The internal elastic lamina is found in 

A blockage of coronary blood flow

True or False: heavy exercise permits flow of blood to nonessential organs

These vessels can expand and recoil

True or False: heavy exercise activates the sympathetic nervous system

minimum arterial pressure at the end of ventricular diastole

Viscosity is ____ times that of water

Arterial pressure

Peptide that responds to excessive diastolic stretching

Cardiac output is impacted by

Peak arterial pressure during ventricular systole

What is generated by the heart to overcome resistance?

The difference in pressure from one end of a vessel to the other

Heavy exercise affects the blood supply to the brain

Pressure across the entire system

Occurs due to friction between blood and vessel walls

True or False: resistance increases as vessel diameter decreases

Which is a sign of damage to veins

Resistance caused by molecules in a liquid

Swirling action that disturbs smooth flow of liquid

Difference between systolic and diastolic pressure

Arterial walls _____ during systole and _____ during diastole

Determines the amount of blood arriving at right atrium each minute

When blood pressure falls, cardiac output

Contains receptors that monitors end of systemic circuit

Blood fills ventricles passively during
