Detailed explanation-1: -They include water, nitrogenous wastes (like urea and creatinine), nutrients (like glucose and amino acids), and salts. These substances are too big to escape the glomerulus and therefore they remain in the blood.
Detailed explanation-2: -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-3: -Explanation: Cells and large proteins are too large to cross the capillary membranes of the glomerulus, and cannot be filtered into Bowman’s capsule. After this initial step of filtration, urine in the nephron is only affected by secretion and reabsorbtion of water, ions, and other small molecules.
Detailed explanation-4: -Proteins and blood cells are too large to pass through the filtration membrane between the blood and the glomerular capsule.
