Lying on back, face upwards

Question 13

Question 14

What do the coronary arteries do?

Answer 14

The blood vessels supply oxygenated blood to the heart muscle

Question 15

What do the artria do?

Answer 15

Receive blood returning to your heart from either the body or lungs and are the upper chambers of the heart.

Question 16

What does the right atrium do?

Answer 16

It receives deoxygenated blood via the superior and inferior vena cava

Question 17

What does the left atrium do?

Answer 17

It receives oxygenated blood from the left and right pulmonary veins

Question 18

What do the ventricles do?

Answer 18

They are the pumping chambers of the heart and they have thicker walls than the artria.

Question 19

What does the right ventricle do?

Answer 19

It lumps blood to the pulmonary (lungs) circulation for the lungs.

Question 20

What does the left ventricle do?

Answer 20

It pumps blood to the systemic circulation for the body.

Question 21

What does the septum do?

Answer 21

The dividing membrane which separates the right and left sides of the heart tissue.

Question 22

What does the bicuspid (mitral) valve do?

Answer 22

It’s between the left atrium and left ventricle and blood only flows in one direction.

Question 23

What is the tricuspid valve?

Answer 23

It’s between the right atrium and right ventricle and blood only flows in one direction.

Question 24

What is the semilunar valves?

Answer 24

The aortic and pulmonary valves and it between the left ventricle and the aorta and valves prevent back flow of blood.

Question 25

What is the chordate tendineae?

Answer 25

It’s chord-like tendons connected to the bicuspid and tricuspid valves to prevent the heart from turning inside out.

Question 26

What are the ventricles?

Answer 26

They are larger than the artria because they eject blood further (lungs and body)

Question 27

What is the pathway of blood through the heart?

Answer 27

Inferior/superior vena cava
Right atrium
Tricuspid valve
Right ventricle
Pulmonary semilunar valve
Pulmonary artery
Lungs
Pulmonary veins
Left atrium
Bicuspid valve
Left ventricle
Aortic semilunar valve
Aorta

Question 28

What are some properties of the arteries?

Answer 28

• Elasticity and contractility and helps maintain blood pressure.
• They are very deep under the skin and branch into smaller arterioles that deliver blood to the capillaries

Question 29

What are arterioles?

Answer 29

They control blood distribution by changing the diameter. It adjusts the blood flow into the capillaries in response to differing demands for oxygen.

Question 30

What do the veins do?

Answer 30

They allow venous return.
