Glomerular Filtration Pressure
The RLO deals with the opposing forces within the glomerulus and the Bowmans capsule which together create the glomerular filtration pressure. The RLO builds on the Starlings Forces RLO by the same author and is intended to form the basis for a future RLO on glomerular filtration rate. This RLO was developed jointly with De Montfort University.
