heart anatomy quiz review

Terms

Pericardium

• fluid filled sac that surrounds the heart

• allows no friction between the heart and the tissues so that both do not get damaged

Fibrous

Serous

Parietal

Visceral

Endocardium

Myocardium

Right Atrium

Left Atrium

Right Ventricle

Left Ventricle

Semilunar valves

• Aortic

• Pulmonary

Atrioventricular Valves

Tricuspid Valve

Bicuspid (Mitral) Valve

Interventricular Septum

Vein

Artery

Concepts

1.       Describe the pathway of blood through the heart starting in the right atrium.

right atrium, tricuspid valve, right ventricle, pulmonary valve, pulmonary artery to go to the lungs to get oxygen,

2.       What is the purpose of the interventricular septum? What happens if this is compromised (e.g. hole-in-the-heart)?

3.       Describe the events leading to a myocardial infarction (heart attack). What is the end result of an MI?

4. Describe the forces that allow each of the heart valves to open and close.

For example – the aortic valve closes when the pressure in the aorta is greater than that of the left ventricle. When the pressure in the left ventricle increases (over the aortic pressure) during contraction (systole), the aortic valve opens to let blood out of the heart.
