What primarily opposes the hydrostatic pressure in the nephron's glomerulus?
Understand the Problem
The question is asking about the factors that oppose hydrostatic pressure in the nephron's glomerulus, specifically in relation to the processes of filtration in the kidneys.
Answer
Hydrostatic pressure in Bowman's capsule.
The hydrostatic pressure in Bowman's capsule primarily opposes the hydrostatic pressure in the nephron's glomerulus.
Answer for screen readers
The hydrostatic pressure in Bowman's capsule primarily opposes the hydrostatic pressure in the nephron's glomerulus.
More Information
In the nephron's glomerulus, hydrostatic pressure in Bowman's capsule (also known as capsular hydrostatic pressure) works against the glomerular capillary hydrostatic pressure to influence the rate and direction of glomerular filtration.
Tips
It's commonly mistaken to consider only the pressures generated by blood flow, but the resistance (pressure) from the capsule is crucial in calculating net filtration.
