The cardiovascular system transports nutrients and removes gaseous waste from the body. It is composed of the heart and the circulatory system. The lymphatic system, which filters blood and removes microorganisms, cellular debris, and waste, works closely with the cardiovascular system. The cardiovascular system functions within the circulatory system as well.
Structures of the Cardiovascular System
The Heart is the organ that supplies blood and oxygen to all parts of the body. Through cardiac conduction, which causes the heart to contract and then relax, the heart produces electrical impulses to supply the blood and oxygen.
The Blood Vessels are intricate networks of hollow tubes that carry blood around the body. They travel from the heart, from arteries to arterioles to capillaries to veins and then back to the heart. The substances carried in blood, like oxygen, carbon dioxide, nutrients, and waste, are exchanged in the process of microcirculation
Blood is what carries and delivers and removes substances during cellular processes such as cellular respiration. It is composed of red blood cells, white blood cells, platelets, and plasma.
