Neco Model Questions Vol1 2018 Biology Question 48
Practice objective / multiple choice question 48 from the 2018 Neco Model Questions Vol1 Biology examination.
In a capillary, the hydrostatic pressure is \(15\ \text{mmHg}\) and the interstitial hydrostatic pressure is \(5\ \text{mmHg}\). The plasma oncotic pressure is \(25\ \text{mmHg}\) and the interstitial oncotic pressure is \(5\ \text{mmHg}\). The filtration coefficient \(K_f\) is \(0.01\ \text{mL min}^{-1}\text{mmHg}^{-1}\) and the reflection coefficient \(\sigma\) is assumed to be 1. (a) Calculate the net filtration rate (in \(\text{mL min}^{-1}\)). (b) If a vasoconstrictor reduces the capillary hydrostatic pressure by 20\%, what is the new net filtration rate?
