2.72 describe ultrafiltration in the Bowman’s capsule and the composition of the glomerular filtrate

Blood arrives in Bowman's casual under the high pressure of an artery, it travels it to the glomerulus where the pressure is further increased (as the tubes are smaller). Components of the blood are forced out of the blood vessel into the glomerulus due to the high pressure, creating glomerulas filtrate (water, slats ect.)

  10. doesnt blood arrive in the glomerulus and filtered into the bowmans capsule? i think u got it the wrong way round

  11. Yes you are right, the blood arrives to the glomerulus through the renal artery and then ultrafiltration occurs separating the molecules from the blood.
