Q

Describe the Heartbeat

A

“lubb”- atrioventricular valves close, atria relax, ventricles contract, “dubb”- semilunar valves close

17
Q

Functions of Blood

A

supplies nutrients, removes waste, equalizes temperature, transports hormones and antibodies

18
Q

Red Blood Cells

A

carry oxygen

19
Q

White Blood Cells

A

defend against invaders

20
Q

Platelets

A

initiate blood clotting

21
Q

Plasma

A

fluid portion of the blood

22
Q

LDL

A

low density lipoprotein, delivers cholesterol, “bad” cholesterol, leads to hypertension, atherosclerosis, stroke, heart attack

23
Q

HDL

A

high density lipoprotein, returns cholesterol to liver for destruction, “good” cholesterol, removes LDL

24
Q

Major Diseases of the Circulatory System

A

hypertension, atherosclerosis, stroke, heart attack

25
Q

Common Risk Factors for Cardiovascular Disease

A

high blood pressure, high bad cholesterol, overnutrition, excess weight, diabetes, underexercise, smoking, heredity, tension/stress

26
Q

Arteries

A

carry blood away from the heart

27
Q

Veins

A

carry blood towards the heart

28
Q

Right Ventricle

A

pumps blood only to the lungs

29
Q

Left Ventricle

A

pumps blood to the rest of the body (not the lungs)
