What is the main function of the circulatory system?

Answer 1

The main function of the circulatory system is to transport oxygen, nutrients, hormones, and other essential molecules to all cells of the body. It also helps in removing waste products and carbon dioxide from the cells and carries them to the organs responsible for their elimination. Additionally, the circulatory system helps in regulating body temperature, maintaining proper pH balance, and defending against infections and diseases through the white blood cells and antibodies it circulates.
