Answer 2

Question - What is the correct path through the circulatory system which describes the passage of blood originating in the left leg? *

1. Vena cava → right atrium → left atrium → lungs → right ventricle → left ventricle → aorta

2. Vena cava → left atrium → right atrium → lungs → left ventricle → right ventricle → aorta

3. Vena cava → right atrium → right ventricle → lungs → left atrium → left ventricle → aorta

4. Vena cava → left atrium → left ventricle → lungs → right atrium → right ventricle → aorta

Answer - 3. Vena cava → right atrium → right ventricle → lungs → left atrium → left ventricle → aorta is the correct path through the circulatory system which describes the passage of blood originating in the left leg.

• The deoxygenated blood from the body is poured from veins into the heart, the right atrium to be specific. The two large veins namely the superior vena cava and inferior vena cava receive the blood.
• This blood passes from the right atrium to the left atrium. It is further transported to the lungs. Here the gaseous exchange takes place, where carbon dioxide is expelled and oxygen is taken in.
• Now, this oxygen-rich blood comes back to the left atrium and flows to the left ventricle.
• Further blood from the left ventricle is passed through aorta to different parts of body.
