Ultrfiltration

2.71 Describe ultrafiltration in the browmam's capsule and the composition of the glomerular filtrate.

Nephron - filtration of blood
results in filtered blood and urine

Urine is composed largely of water, salts and urea (n)

Ultrafiltration = the filtration of molecules

in the bowman's capsule, blood comes in through the afferent arteriole (wide) at high pressure, and leaves through the efferent arteriole (Narrow). This process develops a high pressure in the glomerulous.

The high pressure of blood forces the liquid (Plasma, contents dissolved in blood) out of the blood vessel, into the bowman's capsule, plasma turns into glomerula filtrate (H2O, Salts, A.A., Glucose and urea)
