1. FILTRATION
Blood enters kidney under pressure forcing filtrate through thin walls of glomerulus into Bowman’s Capsule.
FILTRATE
Water, electrolytes, amino acids, glucose, urea, and other small molecules diffuse out of the blood, creating the filtrate.
Items filtered out of the blood into the Bowman's capsule Glucose (but must be returned to the blood by active transport at the loop of Henle) urea salts water |
Items that remain in the blood RBCs WBCs platelets large chemicals like hormones |
Process of filtration
| urine | reabsorption |
