What Are The Three Major Structures Associated With The Circulatory System

The cardiovascular system is an organ system that distributes blood to all parts of the body. The cardiovascular system is a very important system in your body because it is the body delivery system for circulation of blood, which is made up of blood, blood vessels, and the heart. Cardiovascular can be compared to the muscular pump equipped with one-way valves, also a system of large and small plumbing tube where the blood travels through. The circulatory system is important because it transport important materials throughout the body such as blood and nutrient molecules. Without the circulatory system, major organs such as the heart and lungs would fail to work and the body would not receive oxygen. The circulatory system is composed of the
Capillaries are very tiny blood vessels and are one cell thick. Capillaries are the sites of the transfer in oxygen and nutrients from the bloodstream to other tissues in the body. The arteries are strong tubes or vessels that carry blood from your heart to the rest of your body. Arteries transport blood containing oxygen and nutrients to smaller tubes called arterioles, which delivered blood to smaller vessels. Veins take the deoxygenated blood back to the heart. The functions of the circulatory system are respiration, nutrition, waste removal, and immunity. Respiration delivers oxygen to the cells and removing carbon dioxide from them and nutrition carries digested food substances to the cell of the body. Waste removal disposes waste products and poisons that would harm the body and immunity helps protects the body from disease. The circulatory system is a complex network of vessels and organs that is in charge of the hormones, flow of blood, nutrients, and oxygen and other gases to and from the cells. Without the circulatory system, the body could not function properly. The circulatory system maintains homeostasis in a number of ways. In times of need the blood vessels come together to direct the blood to wherever it is required in the body. Also, the circulatory system gets rid of all waste products away from areas where they could build up enough to be toxic and could be very unhealthy for the body. Another way is how blood carries every important nutrient to each part of the human body to help maintain a constant flow and supply to the whole body. Finally, it produces certain hormones in one organ of our bodies that may need to act in another part of the body and it delivers it to the right spot to maintain
