Q

What does the superior vena cava do?

A

Collects deoxygenated blood from the upper body of the heart

27
Q

What does the inferior vena cava do?

A

Collects deoxygenated blood from the lower body into the heart

28
Q

What is blood pressure?

A

The force the aqueous blood exerts on the arterial walls as the heart contracts.

A

Left

34
Q

Which side of the heart is rich in carbon dioxide?

A

Right

35
Q

What do arteries do?

A

Carry blood away from the heart to the capillaries

36
Q

What is the largest artery in the body?

A

The aorta

37
Q

What do veins do?

A

Carry blood back towards the heart for reoxygenation

38
Q

What do capillary beds do?

A

Exchange vessels that transport gasses and nutrients to the cells of the body.

39
Q

What does the lymphatic system consist of? 5

A
  1. Lymph fluid,
  2. lymph nodes,
  3. tonsils,
  4. spleen
  5. Thymus gland
40
Q

What does the lymphatic system do? 3

A
  1. Maintain fluid balance in tissue by filtering blood and lymph fluids
  2. Provides defense against disease
  3. Absorbs fats and other substances from the digestive track
41
Q

How does the lymphatic system play a role within the immune system?

A

By transporting pathogens to lymph nodes where immunity cells destroy them

42
Q

What is the function of the cardiovascular system? 3

A
  1. Transport oxygen to all tissues and remove metabolic waste products
  2. Transport cells to aid in nourishment and immunity of the body
  3. Regulation of body temperature
43
Q

What does the right atrium do?

A

Upper chamber of the heart that Collects blood from the vena cava and propels it through the tricuspid valve

44
Q

What does the right ventricle do?

A

Propels blood into the right and left pulmonary arteries.

45
Q

What does the left atrium do?

A

Blood is returned into the heart after oxygenation by the right and left pulmonary arteries into the upper left atrium and exits through the bicuspid valve In the aorta.

46
Q

What does the aorta do?

A

Returns oxygenated blood back into the body

47
Q

What is a heart attack?

A

Complete or partial obstruction in the coronary arteries.

48
Q

What is the blood/heart circulation path?

Right atrium, right ventricle to the lungs. Then, left ventricle and then left atrium

49
Q

What are the largest veins in the body?

A

Superior/inferior vena cavas

50
Q

What does the cardio do?

A

Brings back carbon dioxide
