Vertebrate Kidney Form • The kidneys receive blood
through the renal artery and filters out waste from the blood.
• The blood is passed through the structure of the kidneys called nephron, where waste products and excess water pass out of the blood stream, as shown in the diagram.

Renal Structure
1 = ureter
2 = pelvis
3 = cortex
4 = medulla

Nephron
• Functional unit of the kidney• Filtration, tubular reabsorption, tubular
secretion• Renal corpuscle:– Glomerulus – capillaries– Glomerular or Bowman’s capsule

Loop of Henle
• Responsible for producing a concentrated urine by forming a concentration gradient within the medulla of kidney.
• A higher concentration on the outside of the loop pulls out water for re-absorption.
• The deeper the loop the more concentrated the pee will be.

Why is it better to drink pee than not drink anything?

• Bowman’s capsule– What: knot of capillaries inside the glomerular capsule
– Fct: Receives filtrate• Nephron loop or Loop of Henle– Regulates concentration of urine
• Collecting duct• Re-absorption of water and electrolytes• Re-absorption stimulate by Anti-Diuretics Hormone
(ADH)
• Capillaries & branch of renal artery:– Supply blood to be filtered

Water leaves – OSMOSIS Salt Leave – Active Transport (uses energy)

To Make Concentrated Urine• You need: – Long loop of henle:• With extreme concentrtion gradient to pull out ater and
salt
– ADH• Anti-diuretic hormone at collecting duct to make it
soluble to water so more water can leave.
