Question

The nearest organ to  which the heart supplies oxygenated blood is 
(a) Lung (b) Stomach (c) intestine   (d) Heart itself
 


Solution

Option d is correct

The heart itself. Like all other the cells the heart muscle cells require oxygen and nutrients in order to function. The heart supplies oxygenated blood to itself via the coronary arteries, which branch off from the aorta. The coronary arteries are very narrow, and thus commonly affected by atherosclerosis, which could lead to a heart attack.
