Question

The nearest organ to which heart supplies oxygenated blood is
A) Lung
B) Stomach
C) Intestine
D) Heart itself

Answer 1

Hint: The heart is the important organ which receives the deoxygenated blood from all parts of the body, sends it for oxygenation and then supplies the oxygenated blood to all the parts of the body. The left and right part of the heart works in the coordinated manner to receive and supply blood.

Complete answer:
Heart is the main organ for pumping blood. It receives deoxygenated blood from all the parts of the body through superior and inferior vena cava in the right part. It then sends the blood to the lungs for oxygenation by the help of pulmonary arteries.

The lungs receive the blood and the diffusion of carbon dioxide from the blood to the alveoli and the oxygen from the alveoli to the blood is done. The right part of the heart is the one which receives oxygenated blood. The ventricles of the heart receive the oxygenated blood from the lungs through the pulmonary vein. Aorta is the major artery which branches and supplies to all the other organs of the body.

The stomach receives the oxygenated blood from the celiac artery. It also supplies the oxygenated blood to the abdomen, spleen, intestines. The right part of the heart is the first organ which receives the oxygenated blood from the lungs.

Therefore the correct answer is option ‘D’.

Note: The deoxygenated blood is collected from the lower part of the body by the help of several veins. These veins merge into inferior vena cava. The upper part of the body transports the deoxygenated blood through superior vena cava to the heart.
