Question

LIST all of the blood vessels & types of blood vessels (including arteries, arterioles, capillaries, venules, and veins), heart chambers & heart valves in the order that a drop of blood would flow through the heart and pulmonary circuit, starting with the superior and inferior vena cava and ending with the drop of blood leaving the heart and going to the body tissues of the systemic circuit.

(*Do this as a numbered LIST, not an essay, starting with

1. Superior and Inferior vena cava

2. ____________ 3. ____________ 4. ____________ until you reach where the drop of blood leaves the heart and is on its way to the body tissues of the systemic circuit. Remember to: LIST ALL specific named blood vessels and the names of any types of blood vessels in the order that the drop of blood would flow through them. Be sure to include all valves of the heart.

Answer 1

Answer

1. Superior and inferior vena cava
2. Right atrium
3. Tricuspid valve
4. Right ventricle
5. Pulmonary semilunar valve
6. Pulmonary trunk
7. Pulmonary arteries (left and right)
8. Pulmonary arterioles
9. Pulmonary capillaries (in lungs surrounding the alveoli)
10. Pulmonary venules
11. Pulmonary veins
12. Left atrium
13. Bicuspid valve
14. Left ventricle
15. Aortic semilunar valve
16. Aorta

• Pulmonary circulation aims to transport deoxygenated blood from right side of the heart to the lungs for its purification.
• After oxygenation the blood return to the left side of the heart.
• Blood leaves the heart to begin systemic circulation when left ventricle pumps the blood into aorta via aortic semilunar valve.
• Aorta is the first artery of systemic circulation that transports the blood to body tissues.
