Question

Choose the correct route of blood flow through the heart from the systemic circulation to the pulmonary circulation and back to the systemic circulation.

1) Left atrium
2) Right atrium
3) Left ventricle
4) Right ventricle
5) Tricuspid valve
6) Pulmonary semilunar valve
7) Mitral or bicuspid valve
8) Aortic semilunar valve

Answer 1

The correct route of blood flow through the heart begins with oxygenated blood in the left atrium and ends with deoxygenated blood in the right atrium. The blood travels through the various chambers and valves of the heart and is pumped to the systemic and pulmonary circulations.

Step-by-step explanation:

The correct route of blood flow through the heart from the systemic circulation to the pulmonary circulation and back to the systemic circulation is as follows:

1. Systemic Circulation (Oxygenated blood from the body) -> Left Atrium
2. Left Atrium -> Bicuspid or Mitral Valve
3. Bicuspid or Mitral Valve -> Left Ventricle
4. Left Ventricle -> Aortic Semilunar Valve
5. Aortic Semilunar Valve -> Aorta (Carries oxygenated blood to the body)
6. Aorta -> Systemic Circulation
7. Pulmonary Circulation (Deoxygenated blood to the lungs) -> Right Atrium
8. Right Atrium -> Tricuspid Valve
9. Tricuspid Valve -> Right Ventricle
10. Right Ventricle -> Pulmonary Semilunar Valve
11. Pulmonary Semilunar Valve -> Pulmonary Arteries (Carries deoxygenated blood to the lungs)
12. Pulmonary Arteries -> Pulmonary Circulation
13. Left Atrium -> Pulmonary Veins (Carries oxygenated blood from the lungs)
