Explanation of Solution
The circulatory system of the body is made up of heart and the blood vessels. Blood vessels that carry oxygenated blood from the heart to the body are called arteries. Nearby tissue arteries are diverged to form microscopic tubular network called capillaries. The capillaries are the site where exchange of the gases between tissue and blood takes place.
The capillaries join to form veins, in the veins, the deoxygenated blood is present, in veins, the blood pressure is not high so, it has valves to prevent the backflow of the blood. The veins deliver the blood in the heart and heart pumps the blood throughout the body. It is a hollow muscular organ. The pacemaker of heart that is present in right atrium sends the signal to the heart for pumping the blood.
The blood is the fluid connective tissue which is composed of plasma, white blood cells, red blood cells, platelets, and proteins. The plasma is a clear yellowish fluid that comprise more than 50% of blood. The function of the red blood cells is to transfer the oxygen from heart to body. The white blood cells are the cells responsible for immunity and body’s disease fighting capability. The fragments of the cells that helps in blood clotting is known as platelets. The blood clots, fats and other components of blood causes a block to artery resulting in a condition called atherosclerosis.
