How do you'r body's cells get the things they need to survive?

Answer 1

Every cell in the body has access to essential nutrients through the circulatory system. Molecules in the blood diffuse out of capillaries where their concentration is high, into surrounding tissue fluid where they are required.

For small molecules, such as water and gasses, this is allowed by tiny holes in the membranes just big enough for them to pass through. Larger molecules such as glycogen and proteins must be drawn into cells by a process called active transport, where gates embedded in the cell membranes are use ATP to pull desired molecules into the cell.
