Answer 7

artery that carries deoxygenated blood from the right ventricle of the heart to the lungs

Question 8

Pulmonary Vein

Answer 8

vein that carries oxygenated blood from the lungs to the left atrium of the heart

Question 9

Left Atrium

Answer 9

the left upper chamber of the heart that receives blood from the pulmonary veins

Question 10

Bicuspid Valve

Answer 10

A valve of the heart, composed of two triangular flaps, that is located between the left atrium and left ventricle and regulates blood flow between these chambers

Question 11

Left Ventricle

Answer 11

the chamber on the left side of the heart that receives arterial blood from the left atrium and pumps it into the aorta

Question 12

Aortic Valve

Answer 12

a semilunar valve between the left ventricle and the aorta; prevents blood from flowing from the aorta back into the heart

Question 13

Aorta
