Q

sa node

A

Initiate the electrical impulse

21
Q

AV node

A

Atria contract, squeezing their blood down into the ventricles

22
Q

Purkinje fibers

A

Causes the ringing contraction of the ventricles, which pumps the blood out of the heart

23
Q

Arteries

A

blood away from heart

24
Q

aorta

A

Largest artery in the body

25
Q

Capillary beds

A

Where oxygen and carbon dioxide are exchanged in the blood

26
Q

Veins

A

Blood back to heart

27
Q

Superior and inferior vena cava

A

Largest veins in the body

28
Q

Systolic pressure

A

Top number, pressure exerted against the walls of the arteries at the peak of the pump

29
Q

Diastolic pressure

A

Bottom number, pressure on the walls of the arteries as the ventricle is resting

30
Q

Atherosclerosis

A

Condition where plaque starts building up on the inside of blood vessel walls causing them to thicken

31
Q

Arteriosclerosis

A

The end stage of the disease where the blood vessel walls are so damaged they become narrowed and hardened, encouraging blood clots to form

32
Q

Aneurysm

A

Blood filled protrusion in the wall of a blood vessel

33
Q

blood vessel order

A

Arteries, arterials, capillaries, venules, veins

34
Q

Artery and vein differences

A

Artery: away, muscular, oxygenated blood

Vain: two, valves, unoxygenated blood

35
Q

Atrium and ventricle differences

A

Atrium: receiving chamber

Ventricle: bigger, muscular, pumping chamber

36
Q

Four valves

A

Pulmonary semi lunar, are you what it semi lunar, right av valve, left av valve

37
Q

44
Q

Carotid artery

A

Neck

45
Q

Femoral

A

Upper leg

46
Q

Superior vena cava

A

Returning blood from head and arms

47
Q

Inferior vena cava

A

Returning blood from legs and abdomen

48
Q

Two major functions of the circulatory system

A

Deliver food and oxygen to cells, spread body heat
