Скачать или смотреть Kidneys Part 2. Starling Forces & How to Calculate Glomerular Filtration Pressure. What GFR is.

This lecture starts by by discussing the organization afferent arteriole, glomerulus, and efferent arteriole. It then explains the anatomy of the glomerulus and how the anatomy of the glomerulus allows for plasma to enter into Bowman's capsule. Next it discusses the Starling forces. First it explains glomerular hydrostatic pressure and then Bowman's Hydrostatic Pressure. Next it discusses how Bowman's hydrostatic pressure can impact filtration. It then compares glomerular and Bowman's osmotic pressure followed by a discussion of how all the Starling forces are used to calculate glomerular filtration pressure. It finishes by explaining what glomerular filtration rate and filtration fraction are.
