20
Q

: Supply oxygen rich blood to the heart muscle .

A

Coronary arteries

21
Q

– Between lungs and heart only
– Carries deoxygenated blood away from the heart, to the lungs, and returns oxygenated blood back to the heart. What is this

A

Pulmonary circuit

22
Q

Pulmonary___: carry deoxygenated blood to lungs.

A

arteries

23
Q

Pulmonary___: carry oxygenated blood to heart.

A

veins

24
Q

other wastes from cells .
o Only one cell thick (epithelial cell).

A

Capillaries

29
Q

Which vessel. o Return blood back to the heart.
o Havevalves
o Carry deoxygenated blood except pulmonary veins.
o Thinner vessel walls with less smooth muscles than arteries.

A

Veins

30
Q

31
Q

:
Is defined as the maximum pressure in the arteries exerted during ventricular
contraction .

A

Systolic pressure

32
Q

:
Is the minimum pressure exerted when ventricles relax and fill

A

Diastolic pressure

33

Q

Functions of blood

A

▪ Transportation: transports oxygen and nutrients to cells, remove CO2 and waste away from cells.
▪ Regulation: maintain stable body temperature, pH, water and electrolyte levels.
▪ Protection: white blood cells protect body against disease
