What are the 3 main types of blood vessels in the body

A

Arteries, Capillaries and Veins

38
Q

What does the left side of the heart do?

A

It pumps oxygenated blood

39
Q

What does the right side of the heart do?

A

It pumps de-oxygenated blood

40
Q

Are the atria found at the top or bottom of the heart.

A

Top

41
Q

Are the ventricles found at the top or bottom of the heart

A

Bottom

42
Q

If you are looking at a diagram of the heart where would the right side of the heart be from your point of view

A

On the left side

43
Q

Which chambers have thicker walls, the atria or the ventricles

A

The ventricles

44
Q

What does the word ‘Pulmonary’ likely involve

A

The Lungs

45
Q

What is the pathway of oxygenated blood

A

Lungs -> Pulmonary vein -> Left atrium -> Mitral/Bicuspid valve -> Left Ventricle -> Aortic Valve -> Aorta

46
Q

What is the Aorta?

A

The Aorta is a major artery that sends out oxygenated blood throughout the body.

47
Q

How does the heart get its own blood?

A

Through the Coronary Arteries

48
Q

What do the coronary arteries branch off of?

A

The Aorta

49
Q

What do the coronary arteries eventually deliver blood to?

A

The Capillaries

50
Q

What do the capillaries that the coronary arteries deliver blood to give to the heart

A

Oxygen and Glucose

51
Q

What do the coronary veins do?

A

They take the de-oxygenated blood to the right atrium, so the blood can become oxygenated again.

52
Q

About how many times does the human heart beat per day?

A

Over 100,000 times

53
Q

What do Phagocytes do

A

They eat the foreign bodies that enter your body, so the body has a less likely chance to be infected or for you to get sick

54
Q

What do Lymphocytes do

A

They create Anti-bodies to destroy the harmful bacteria.
