Glossary - Heart

Question 1

aorta

Answer 1

the biggest and longest artery (a blood vessel carrying blood away from the heart) inthe body. It carries oxygen-rich blood from the left ventricle of the heart to the body

Question 2

inferior vena cava

Answer 2

a large vein (a blood vessel carrying blood to the heart) that carries oxygen-poor blood to the right atrium from the lower half of the body.

Question 3

inferior vena cava

Answer 3

a large vein (a blood vessel carrying blood to the heart) that carries oxygen-poor blood to the right atrium from the lower half of the body.

Question 4

left atrium

Answer 4

the left upper chamber of the heart. It receives oxygen-rich blood from the lungs via the pulmonary vein.

Question 5

left ventricle

Answer 5

the left lower chamber of the heart. It pumps the blood through the aortic valve into the aorta.

Question 6

mitral valve

Answer 6

The valve between the left atrium and the left ventricle. It prevents the back-flow of blood from the ventricle to the atrium.

Question 7

pulmonary artery

Answer 7

the blood vessel that carries oxygen-poor blood from the right ventricle of the heart to the lungs.

Question 8

pulmonary valve

Answer 8

the flaps between the right ventricle and the pulmonary artery. When the ventricle contracts, the valve opens, causing blood to rush into the pulmonary artery. When the ventricle relaxes, the valves close, preventing the back-flow of blood from the pulmonary artery to the right atrium.

Question 9

pulmonary vein

Answer 9

the blood vessel that carries oxygen-rich blood from the lungs to the left atrium of the heart.

Question 10

right atrium

Answer 10

the right upper chamber of the heart. It receives oxygen-poor blood from the body through the inferior vena cava and the superior vena cava.

Question 11

right ventricle

Answer 11

the right lower chamber of the heart. It pumps the blood into the pulmonary artery.

Question 12

septum

Answer 12

the muscular wall that separates the left and right sides of the heart.

Question 13

superior vena cava

Answer 13

a large vein that carries oxygen-poor blood to the right atrium from the upper parts of the body.

Question 14

tricuspid valve

Answer 14

the flaps between the right atrium and the right ventricle. It is composed of three leaf-like parts and prevents the back-flow of blood from the ventricle to the atrium.
