Ultra-filtration mechanisms in the kidney
The Kidney: This feature displays the mammalian kidney at a range of levels, from its location within the body cavity, down to the cellular level to demonstrate the ultra-filtration mechanism. Arterial blood enters the kidney carrying a range of waste products from around the body, it leaves the kidneys with these products removed. The process involves physical filtration, when blood fluids and dissolved wastes are forced through porous capillary walls in the capsules, followed by an active re-absorption of water, salts and sugars from the waste stream in the tubules and loop of Henle.
