The filtration of the blood takes place in the Nephron. There are two products- Filtered blood (clean) and the waste (urine).
The urine (water, salts and urea) drains into the bladder from the pelvic region.
- The blood arrives in the kidney through the Afferent Arteriole
- The Arteriole begins to branch off and create a twisted knot-like structure Glomerulus
- The diameter of the Efferent Arteriole is smaller
- This creates a high pressure
- Plasma (water, salts, amino acids, glucose and urea) forced out of the blood vessel and into the inside of Bowman's capsule
- This is now called the Glomerular filtrate
