The Bowman’s capsule (renal capsule):
surrounds a ball of capillaries called the capillary knot
high pressure is created in the capillary knot by the diameter of the capillary leaving the knot being narrower than the capillary entering
this pressure results in ultrafiltration where water, salts, glucose, and other small molecules pass out of the capillary and into the Bowman's capsule
proteins and blood cells are too big to leave the capillaries to go into the tubule
The rest of the tubule is responsible for the selective reabsorption of glucose, some salts, and lots of the water.
The collecting duct is responsible for the selective reabsorption of water and for sending urine to the ureter.
