What is "bloodstream"?

The bloodstream refers to the collective system of blood vessels that carry blood throughout the body. It serves as a vital transportation network, delivering oxygen, nutrients, hormones, and other essential substances to cells and tissues while removing waste products and carbon dioxide. The bloodstream is powered by the pumping action of the heart, and its intricate network of arteries, veins, and capillaries ensures efficient circulation. It plays a crucial role in maintaining homeostasis, regulating body temperature, supporting immune function, and distributing necessary components for cellular functions.
