Name the blood vessel that brings (i) oxygenated blood (ii) deoxygenated blood, to the human heart. Also name that chamber of the heart which receives deoxygenated blood and state how deoxygenated blood from this chamber is sent to lungs for oxygenation.
Name the blood vessel that brings (i) oxygenated blood (ii) deoxygenated blood, to the human heart. Also name that chamber of the heart which receives deoxygenated blood and state how deoxygenated blood from this chamber is sent to lungs for oxygenation.
The blood vessels that bring oxygenated and deoxygenated blood to the heart are: (i) Oxygenated blood: Pulmonary veins (ii) Deoxygenated blood: Superior and inferior vena cava The chamber of the heart that receives deoxygenated blood is the right atrium. Deoxygenated blood from the right atrium is sent to the lungs for oxygenation through the right ventricle and the pulmonary arteries.
Marking Scheme
- 1/2 for correct blood vessels
- 2/1 for correct chamber of the heart
Quick Oral Answer
The blood vessels that bring oxygenated and deoxygenated blood to the heart are the pulmonary veins and the superior and inferior vena cava, respectively. The chamber of the heart that receives deoxygenated blood is the right atrium. Deoxygenated blood from the right atrium is sent to the lungs for oxygenation through the right ventricle and the pulmonary arteries.
Analysis & Explanation

The student should be able to identify the blood vessels that bring oxygenated and deoxygenated blood to the heart and the chamber of the heart that receives deoxygenated blood. The student should also be able to explain how deoxygenated blood is sent to the lungs for oxygenation.
Common Mistakes
- 1confusing the blood vessels that bring oxygenated and deoxygenated blood to the heart
- 2not specifying the chamber of the heart that receives deoxygenated blood
Interesting Facts
The human heart pumps around 2,000 gallons of blood every day.
The blood vessels in the human body are so long that if they were laid end to end, they would circle the Earth twice.
