Valve

What is the function of the valves?

to prevent backflow of blood

What mechanisms help in venous return?

Skeletal muscle pump, respiratory muscle pump, valves

Endothelium

A BLANK is rhythmic pressure oscillation that accompanies every heartbeat.

Pulse

Pulse pressure = ?

Difference between systolic and diastolic pressure

What is the pressure that propels the blood to the tissues?

Mean arterial pressure (MAP)

MAP = ?

Diastolic pressure + 1/3 pulse pressure

Pulse pressure and MAP both BLANK with increasing distance from the heart

Decline

Efficiency of the circulation can be assessed by taking BLANK and BLANK.

pulse, blood pressure

Low BP in which systolic pressure is below 100 mm Hg

Hypotension

Condition of sustained elevated arterial pressure of 140/90 or higher

Hypertension

BLANK - pressure changes created during breathing suck blood toward the heart by squeezing local veins

Respiratory pump

BLANK - contraction of skeletal muscles “milk” blood toward the heart

Muscular pump

BLANK prevent backflow during venous return
