What does the circulatory system do in body?
The circulatory system has many functions, including:
-Delivering oxygen to the body's cells. Oxygen is a gas that is essential for life. It is absorbed from the air by the lungs and then carried by the blood to the body's cells.
-Removing waste products from the body's cells. Waste products, such as carbon dioxide, are produced by the body's cells as they metabolize food. These waste products are carried by the blood to the lungs and kidneys, where they are removed from the body.
-Regulating the body's temperature. The circulatory system helps to regulate the body's temperature by transferring heat from warmer parts of the body to cooler parts.
-Protecting the body from infection. The circulatory system helps to protect the body from infection by carrying white blood cells to areas where they are needed. White blood cells help to kill bacteria and other microorganisms.
The circulatory system is a complex and vital system. It plays a crucial role in keeping the body healthy and functioning properly.
