Cortex
Medulla
Renal artery
Renal vein

3. Each KIDNEY consists of 1 million NEPHRONS
Each nephron consists of a:
GLOMERULUS (found in cortex)
forms a protein-free filtrate from blood
TUBULE (found in medulla)
processes the filtrate to form urine
Each TUBULE consists of several segments:
Proximal tubule
Loop of Henle
Distal Tubule
Collecting Ducts.
4. Functional Unit of the Kidney is the NEPHRON
Glomerulus
Proximal Tubule
Loop of Henle
Distal Tubule
Collecting Duct
5. Kidney Functions
1. Regulation of water, electrolyte balance,
pH
2. Removal of waste from blood and
excretion of urine.
3. Secretion of hormones
