Functions of cardiovascular system
Transport oxygen, nutrients, cell wastes, hormones to and from cells.
The cardiovascular system, also known as the circulatory system, is responsible for the transportation of important substances throughout the body. The main functions of the cardiovascular system include:
1. Transportation of oxygen and nutrients: The cardiovascular system transports oxygen and nutrients to cells throughout the body. Oxygen is transported through red blood cells, and nutrients are transported through the plasma component of blood. This is essential for proper cellular function and energy production.
2. Removal of waste products: The cardiovascular system also plays a role in the removal of waste products from the body. Carbon dioxide and other waste products are transported away from cells and eventually eliminated from the body through the lungs, kidneys, and digestive system.
3. Maintenance of blood pressure: The cardiovascular system helps to maintain proper blood pressure levels by adjusting the diameter of blood vessels and regulating the amount of blood that is pumped by the heart.
4. Regulation of body temperature: Blood vessels in the skin help to regulate body temperature by dilating (widening) or constricting (narrowing) based on environmental factors and the body’s needs. This helps to maintain a constant internal body temperature.
5. Immunological defense: The cardiovascular system can also help to defend against infections and diseases through the white blood cells which are transported throughout the body via the circulatory system.
Overall, the cardiovascular system plays an integral role in maintaining homeostasis in the human body.
