Make labeled diagram of nephron and explain the mechanism of urine formation in human being.
Urine formation involves three process:
1.Glomerular filtration - Filtration of water and dissolved substances out of the blood
in the glomeruli and into Bowman's capsule
2.Reabsorption - Reabsorption of water and dissolved substances out of the kidney
tubules back into the blood. This process prevents substances required by the body
from being lost in the urine.
3.Secretion - Secretion of hydrogen ions H+, potassium ions K+ , ammonia NH3,
and certain drugs out of the blood and into the kidney tubules, where they are
eventually eliminated in the urine.
