What is the process of bodily fluids moving in the blood stream?

The movement of bodily fluids in the bloodstream primarily involves the circulation of blood, which transports various components such as nutrients, hormones, and waste products. Blood is pumped by the heart through a network of arteries and veins, allowing it to flow continuously throughout the body. As blood circulates, it exchanges gases and nutrients with tissues at the capillaries, where fluids can move in and out of the bloodstream via diffusion and osmotic pressure. This process ensures that cells receive necessary substances and remove metabolic waste efficiently.
