Detailed explanation-1: -The basement membrane of the glomerulus is partially permeable and allows small molecules like glucose to pass through. Q. In a healthy person, some glucose is reabsorbed into the bloodstream while majority is lost in the urine.

Detailed explanation-2: -The function of glomerulus is to filter the blood passing through it and initiate urine formation.

Detailed explanation-3: -The glomerulus filters your blood As blood flows into each nephron, it enters a cluster of tiny blood vessels-the glomerulus. The thin walls of the glomerulus allow smaller molecules, wastes, and fluid-mostly water-to pass into the tubule. Larger molecules, such as proteins and blood cells, stay in the blood vessel.

Detailed explanation-4: -Most of the glucose entering the tubular system is reabsorbed along the nephron segments, primarily in the proximal tubule, such that urine is almost free of glucose.

Detailed explanation-5: -Blood enters the glomerulus under high pressure, forcing substances across the leaky endothelial-capsular membrane into the nephron. This membrane acts like a sieve allowing small substances to be filtered into the nephron, whilst large molecules such as plasma proteins remain within the blood.
