Question

Identify the functions of a nephron. Describe in detail what happens to fluids (blood, filtrate, and urine) as they pass through the parts of a nephron.

Answer 1

<!--br {mso-data-placement:same-cell;}--> The functions of a nephron are filtering materials out of the blood, allowing needed materials to be absorbed back into the blood, and secreting additional materials from the blood to form urine. As blood passes through capillaries in the glomerulus, substances are filtered out of blood and pass into Bowman’s capsule and then the renal tubule. The filtered substances form a fluid called filtrate. As filtrate passes through the renal tubule, some substances are reabsorbed into the blood from the filtrate, and other substances are secreted from the blood into the filtrate, forming urine.
