A&P 5.1 (part 4: physiology of circulation)

?

• A measure of heart rate by counting the blank waves created by blank of the ventricles

• Can be felt in blank close to the body surface as blank walls, expand, and recoil

• Pulse is often measured in the blank artery of the wrist

pulse

• pressure and contraction

• Arteries and artery

• Radial

?

• The blank of blood pushing against the inner walls of blood vessels

• Keeps blood moving even between blank

• Expressed as a fraction with a blank pressure over blank pressure

• Normal blood pressure is less than blank

blood pressure

• pressure

• Heartbeats

• Systolic and diastolic

• 120/80

High blood pressure is also known as what

Hypertension

High blood pressure can be caused by any situation or condition that causes the vessels to blank or blank

Stiffen or narrow

what are the three main causes of high blood pressure?

Smoking, obesity, or lack of exercise

?

• Some types of capillaries are “blank” than others

• Substances exchange between body cells and capillaries first diffuse through blank fluid

• Most substances are exchanged by blank along their blank gradients

capillary exchange

• leakier

• Interstitial

• Diffusion

• Concentration

?

• The movement of fluid is determined by blank pressure and blank pressure

• Blood pressure pushes fluids, blank of capillaries

• Blank pressure tends to draw fluids back in

fluid movement at capillaries

• Blood and osmotic

• Out

• Osmotic
