Blood Vessels and Circulation Pt. 2

The total capillary blood flow

• blood flow

• cardiac input

• cardiac output

• pressure gradient

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

• first phase of ventricular systole.

• Second phase of ventricular systole.

• late phase of ventricular diastole.

• Atrial Systole

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

• AV node

• bundle brances

• SA node

• purkinje fibers

Angiotensin II will cause

• vasodilation

• water and sodium excretion

• water and sodium retention

• increased diuresis

These vessels function in the exchange of substances.

• veins

• capillaries

• arteries

• venules

• arterioles
