Consider the following statements regarding human renal physiology: 1. The functional filtration unit of the mammalian kidney is the nephron, consisting of a renal corpuscle and renal tubule. 2. Glomerular filtration is an active transport process requiring direct consumption of adenosine triphosphate by podocyte cells. Which of the statements given above is/are correct?

💡 Solution & Explanation

Statement one is correct because the nephron is the structural and functional unit of the kidney responsible for filtering blood and forming urine. Statement two is incorrect because glomerular filtration is a passive physical process driven by the hydrostatic blood pressure within the glomerular capillaries rather than active transport requiring cellular energy expenditure. The kidneys maintain fluid and electrolyte homeostasis in the human body.
