Nephron of the kidney (shown) - carries out filtration of blood
two things : Filtered blood (clean blood) and waste blood, Urine
Urine emerges from bottom of tubule - Composed of H2O, Salts and Urea(nitrogen waste) - goes into pelvic region
Bowmans capsule - where filtration begins - Ultrafiltration
Filtration begins when blood comes in the Afferent arteriole (high pressure - wide)
- starts to branch into twists and coils - Glomerulus
- Blood vessel coming out - Efferent arteiole (smaller diameter) - develops high pressure
- High pressure forces the liquid in blood (Plasma) out of the blood vessel into the inside of the Bowmans capsule
Plasma - H2O - Salts - Amino Acids - Glucose - Urea
When it is the bowmans capsule it is called Glomerula filtrate (contains plasma)
Blood has been filtered by pressure due to the smaller diameter arteriole, generating a high pressure in the glomerulus, forcing the liquid into the tube
