The role of the circulatory system in the body is crucial for maintaining homeostasis. This system is responsible for transporting oxygen, nutrients, hormones, and waste products to and from cells. The heart pumps blood through a network of blood vessels, ensuring efficient delivery of essential substances. Additionally, the circulatory system helps regulate temperature, pH, and fluid balance, supporting overall health. Its proper functioning is vital for the well-being of all bodily systems and processes.
