Diffusion is the movement of atoms or molecules from an area of high concentration to an area of low concentration down a concentration gradient. Osmosis is the spontaneous movement of water particles from a region of high concentration to a region of low concentration through a selectively permeable membrane.
What is osmotic pressure? Osmotic Pressure is the minimum amount of pressure needed to be applied to a solution to prevent the inward flow of water across a selectively permeable membrane.
Identify and discuss various buffer systems found in the body. The buffer system in the body is the Bicarbonate Buffer System. The bicarbonate buffer system is an acid/base mechanism which involves the balance of Carbonic Acid (H_2 〖CO〗_3), Bicarbonate Ion (〖HCO〗_3^-), and Carbon Dioxide (〖CO〗_2) so that the pH in the blood and duodenum can be maintained, among all other tissues and to support metabolic functions. A catalyzed reaction also takes place forming this equation:
〖CO〗_2+H_2 O⇋H_2 〖CO〗_3⇋〖HCO〗_3^-+H^+
