I can explain how particles of substances move into and out of the blood by diffusion, osmosis and active transport.
Muuji qoraalka
Particles of substances move into and out of the blood through selectively-permeable cell membranes.
Oxygen, carbon dioxide and other small particles move into and out of the blood by diffusion.
Water moves into and out of the blood by osmosis, a type of diffusion.
The net movement of particles by diffusion and osmosis is down a concentration gradient.
Large particles are moved into and out of the blood by active transport, which requires energy.
