Superior Vena Cava -> Left Atrium -> Mitral Valve -> Left Ventricle -> Aortic Valve -> Aorta

Pulmonary Vein -> Left Atrium -> Mitral Valve -> Left Ventricle -> Aortic Valve -> Aorta

Pulmonary Vein -> Left Atrium -> Mitral Valve -> Left Ventricle -> Aortic Valve -> Aorta

Pulmonary Artery -> Right Atrium -> Tricuspid Valve -> Right Ventricle -> Pulmonary Valve -> Aorta

Inferior Vena Cava -> Right Atrium -> Tricuspid Valve -> Right Ventricle -> Pulmonary Valve -> Pulmonary Artery

How does the heart muscle receive its own supply of oxygen and glucose?

Through coronary arteries that branch off the aorta.

Directly from the blood flowing through its chambers.

Via the pulmonary veins after blood is oxygenated.

From the inferior vena cava, which delivers deoxygenated blood.

What is the primary function of capillaries in the circulatory system?

To allow exchange of materials between blood and cells

To carry blood away from the heart

To pump blood through the heart
