Question 1

• (Small upper chambers)

Answer 1

ATRIA

Question 2

• (Lower chambers)

Answer 2

VENTRICLES

Question 3

• Helps oxygen-rich blood reach organs and tissues in your upper body. It is responsible for carrying blood from the aorta to the right subclavian artery and right common carotid artery.

Answer 3

• BRACHIOCEPHALIC ARTERY

Question 4

• It carries oxygen-rich blood/oxygenated blood from the lungs to the left atrium of the heart. From there, the heart sends the blood to all the other organs and tissues.

Answer 4

• PULMONARY VEINS

Question 5

*- carries oxygen-poor blood to the heart’s right atrium, where it moves into the right ventricle and then to the lungs (through the pulmonary artery) to trade in carbon dioxide for oxygen.

Answer 5

SUPERIOR VENA CAVA

Question 6

• It allows blood to cross the atria and bypass pulmonary circulation during fetal development.

Answer 6

• FOSSA OVALIS

Question 7

• receives oxygen-poor blood from the body and pumps it to the right ventricle.

Answer 7

RIGHT ATRIUM

Question 8

• It drains deoxygenated blood from the heart muscle.

Answer 8

• CORONARY SINUS

Question 9

• controls the blood flow between the heart’s top chamber (RA) to the bottom chamber (RV).

Answer 9

• TRICUSPID VALVE (Right atrioventricular valve)

Question 10

• carries deoxygenated blood from the lower parts of the body and empties into the right atrium (RA) of the heart.

Answer 10

• INFERIOR VENA CAVA (Posterior vena cava)

Question 11

• prevents the backflow of blood from the pulmonary artery back into the right ventricle (RV) in diastole (relaxed phase of the cardiac cycle).

Answer 11

• PULMONARY VALVE

Question 12

• pumps oxygen-poor blood/ deoxygenated blood to the lungs.

Answer 12

• RIGHT VENTRICLE

Question 13

• their contraction pulls on the chordae tendineae, preventing prolapsed mitral (bicuspid) and tricuspid valves.

Answer 13

• TRABECULAE CARNEAE

Question 14

• separates the ventricles and allows for proper blood flow through the heart. It prevents the mixing of oxygenated and deoxygenated blood.

Answer 14

• INTERVENTRICULAR SEPTUM

Question 15

• responsible for the contraction of the heart chambers.

Answer 15

• MYOCARDIUM

Question 16

• pump oxygenated blood from the heart to the rest of the body.

Answer 16

• LEFT VENTRICLE

Question 17

• they contract to prevent inversion or prolapsed of the valves during systole.

Answer 17

PAPILLARY MUSCLE

Question 18

• controls the blood flowing out from the heart.

Answer 18

• AORTIC VALVE

Question 19

• connect the papillary muscles to the tricuspid valve and the mitral valve in the heart. It maintains the atrioventricular valves (TV) in place when the heart pumps blood.

Answer 19

• CHORDAE TENDINEAE

Question 20

• regulates blood flow from the upper left chamber (LA) into the lower left chamber (LV).

Answer 20

• MITRAL VALVE

Question 21

• receives oxygenated blood from the lungs via the pulmonary veins and deliver it to the left ventricle (LV).

Answer 21

• LEFT ATRIUM

Question 22

• carry deoxygenated blood fro the heart to the lungs.

Answer 22

• PULMONARY ARTERY

Question 23

• • it is the largest artery in the body which receives blood directly from the left ventricle (main pumping chamber)/ it transports oxygenated blood from the left ventricle of the heart to every organ.

Answer 23

AORTA

Question 24

• carries oxygen-rich blood from the heart to the upper body.

Answer 24

• LEFT SUBCLAVIAN ARTERY

Question 25

- send oxygen-rich blood to the brain and other parts of the head and neck,

Answer 25

* LEFT COMMON CAROTID ARTERY
