A

Water plasma proteins other nutrients

31
Q

What is hemoglobin

A

A protein in erythrocytes

32
Q

What does hemoglobin do

A

Carries oxygen from lungs to body’s tissues and returns co2 from tissues to lungs

33
Q

What do leukocytes do

A

Immune response

A

Helping blood clot

35
Q

What does blood travel through

A

Vessels

36
Q

What are Arteries

A

Vessels that carry blood away from heart

37
Q

Why are arteries thick

A

To withstand heartbeat

38
Q

What are small branches of arteries

A

Arteriols

39
Q

What do arteries attach to

A

A

Carry blood from body to heart

42
Q

What are veins connected to

A

Capillary beds (venules)

43
Q

Why are veins thin

A

They are away from the heart

44
Q

Why are veins one way

A

Prevents blood from going back

45
Q

What is systemic circulation

A

Right side of oxygenated blood from lungs to body

46
Q

Pulmonary circulation

A

Right side pumps deoxygenated blood from heart to lungs

47
Q

What do valves do

A

Regulate blood flow

48
Q

The left

55
Q

What is the aortic valve responsible for

A

Movement of blood around body

56
Q

Why do we need movement of blood

A

Permits nutrients distribution of waste removal and protection
