The process of filtration mainly occurs in the Bowman's capsule. Here's a breakdown:
1. Bowman's capsule is a part of the nephron in the kidney.
2. When blood enters the glomerulus (a cluster of capillaries within the Bowman's capsule), filtration takes place.
3. Filtration is the movement of water and solutes from the blood into the renal tubule (beginning with the Bowman's capsule).
4. Substances like water, ions, glucose, and waste products are filtered from the blood into the nephron through small pores in the capillaries and the Bowman's capsule.
Therefore, filtration mainly occurs in the Bowman's capsule as the initial step in the process of forming urine in the kidneys.
