Ultra-filtration mechanisms in the kidney |
|
The Kidney: This movie demonstrates the ultra-filtration mechanism in the mammalian kidney. 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. The movie (50kB) is FLASH v6, and may require an upgrade plugin for your browser. The more recent version of FLASH includes accessibility options, intended to help visually impaired visitors access material. Return to education |
