Circulation of body fluids is called circulatory system/internal transport. The substance moved into and out of the body and distance traveled by them increases with the increase in size and complexity of the organism. Therefore, simple diffusion do not serve the required purpose thereby necessitating the transport by fluid circulation. The material that needs to be transported in the body includes nutrients, waste gases, molecules and cells that protect our body from disease. The circulatory system consists of blood, blood vessels, and heart. So, take this quiz and increase your knowledge about the circulatory system.
