Digested food pass the wall of ileum into the blood for transport to other parts of the body through the process of diffusion.
Diffusion is involved in excretion of nitrogenous wastes.
Gaseous exchange across the structures of gaseous exchange such as gills, lungs and tracheal system occurs due to diffusion. Diffusion also enables transport of respiratory gases in and out of the body cells.
