Question

Identify a, b, c, d and e.

• A. a- Superior vena cava, b- Inferior vena cava, c- Pulmonary artery, d- Aorta, e- Pulmonary vein
• B. a- Superior vena cava, b- Inferior vena cava, c- Pulmonary vein, d- Aorta, e- Pulmonary arteries
• C. a- Inferior vena cava, b- Superior vena cava, c- Pulmonary artery, d- Aorta, e- Pulmonary vein
• D. a- Inferior vena cava, b- Superior vena cava, c- Pulmonary vein, d- Aorta, e- Pulmonary arteries

Answer 1

The correct option is A a- Superior vena cava, b- Inferior vena cava, c- Pulmonary artery, d- Aorta, e- Pulmonary vein

The heart is a pumping organ that pumps blood throughout the body.

• Superior vena cava and inferior vena cava are the blood vessels that bring the deoxygenated blood from the body to the right atrium of the body. In the diagram, (a.) and (b.) are the superior and inferior vena cava respectively.
• The pulmonary artery supplies blood into the lungs from the heart. In diagram (c.) is the pulmonary artery.
• Aorta is the main blood vessel that carries oxygenated blood from the heart to the entire body. In this diagram (d.) is the aorta.
• Pulmonary veins are the blood vessels that carry oxygenated blood from the lungs to the left atrium. In this diagram (e.) are the pulmonary veins.

So, the correct answer is (A).
