(B) (a) Identify 'X' in the figure of human nephron shown below. What role does it play in the process of urine formation ?
(b) Why some substances are selectively reabsorbed from the initial filtrate of urine, as it flows along the tabular part of nephron ?
The correct answer is B. The figure shows a human nephron, which is the functional unit of the kidney responsible for filtering waste and excess substances from the blood. The 'X' in the figure represents the glomerulus, a cluster of blood vessels that filters the blood and produces the initial filtrate of urine. The glomerulus plays a crucial role in the process of urine formation by allowing small molecules such as water, ions, and glucose to pass through while keeping larger molecules like proteins and blood cells in the bloodstream. The initial filtrate then flows through the tubular part of the nephron, where some substances are selectively reabsorbed back into the bloodstream. This process helps to regulate the concentration of substances in the body and maintain proper bodily functions.
