What are the primary functions of the human circulatory system?
The human circulatory system, also known as the cardiovascular system, is responsible for transporting blood, oxygen, nutrients, and hormones to different parts of the body. It consists of the heart, blood vessels, and blood.
The primary functions of the circulatory system include:
- Transportation: The system transports blood, nutrients, oxygen, and hormones to different parts of the body. It also transports waste products, such as carbon dioxide, away from the cells.
- Protection: The system helps protect the body by carrying white blood cells that fight against pathogens and foreign substances.
- Regulation: The system helps regulate body temperature and maintains the pH balance in the body.
The heart, which is the main organ of the circulatory system, plays a crucial role in maintaining circulation. It pumps blood throughout the body and ensures that different parts of the body receive the necessary nutrients and oxygen. Blood vessels, on the other hand, act as conduits that transport blood to different parts of the body.
