structures within the heart that open and close with the heartbeat to regulate the one-way flow of blood

Question 33

aortic valve

Answer 33

heart valve between the left ventricle and the aorta

Question 34

mitral valve, bicuspid valve

Answer 34

heart valve between the left atrium and left ventricle (cuspis = point)

low blood pressure

Question 47

hypertension (HTN)
