Verified step by step guidance

Understand the concept of glomerular filtration: Glomerular filtration is the process by which the kidneys filter blood, removing excess waste and fluids to form urine. It occurs in the glomeruli of the nephron and is primarily driven by hydrostatic pressure.

Clarify the mechanism: Glomerular filtration is a passive process, meaning it does not require energy input from ATP or cellular respiration. Instead, it relies on the pressure gradient created by the blood flowing into the glomerulus.

Eliminate incorrect options: Review the provided statements. The options suggesting that glomerular filtration occurs only during dehydration, requires energy from cellular respiration, or is ATP-driven active transport are incorrect because they contradict the passive nature of the process.

Focus on hydrostatic pressure: Hydrostatic pressure is the force exerted by the blood against the walls of the glomerular capillaries. This pressure pushes water and solutes through the filtration membrane into the Bowman's capsule, forming the filtrate.

Select the correct statement: Based on the explanation, the correct statement is 'Glomerular filtration is a passive process driven by hydrostatic pressure.' This aligns with the physiological mechanism of filtration in the kidneys.
