Hint:The circulatory system consists of many organs and the blood vessels. The heart is the main organ of the circulation. The heart pumps the blood and it is transported to all the parts of the body by the blood vessels like arteries, veins and the capillaries.

Complete answer:
The blood has the red blood cells, white blood cells and the platelets. The red blood cells possess the hemoglobin. These compounds are made up of the iron and they are able to carry the oxygen from the alveoli to all the parts of the body. This oxygen is used for the cell respiration and the carbon dioxide from the cell is also taken by these compounds to the alveoli of the lungs.

The blood also contains the nutrients and hormones and discharge from the site of the production to the site of usage. This also helps in maintaining the body temperature and thus helps in the maintenance of the homeostasis of the body. But the urea is not formed by the circulatory system, but it was produced in the urea cycle of the excretory system.

Thus, the correct answer is option (C)

Note: In the arteries, the blood with the red blood cells of the oxyhemoglobin flows where the veins carry the RBC with the deoxygenated blood. Except the pulmonary artery and the pulmonary veins. They move to and from the heart and the lungs.
