1

What’s osmoregulation

The homeostatic control of the water potential of the blood

2

MAKE SURE U CAN LABEL THE KIDNEY

list the 7 structures in the kidney and what they do

Fibrous capsule - an outer membrane that protects the kidney

Cortex - made up of renal capsules, convoluted tubes and blood vessels

Medulla- made up of loops of henle, collecting ducts and blood vessels

Renal pelvis - collects urine into ureter

Ureter - a tube that carries urine to bladder

Renal artery - supplies kidney with blood from the heart via the Aorta

Renal vein - returns blood to heart via vena cava

3

What is each nephron made up of

Bowmans capsule - surrounds glomerulus

Proximal convoluted tube - walls are made of epithelial cells which have microvilli

Loop of henle - ascending and descending limb

Distal convoluted tubule - surrounded by fewer capillaries then proximal

Collecting duct - where tubules empty

4

What are the blood vessels associated with each nephron

Afferent arterioles - supplied with nephron with blood

Glomerulus - fluid is forced out of the blood

Efferent arteriole - carries blood away from the renal capsule and has a smaller diameter then afferent so increase blood pressure within glomerulus

Blood capillaries- reabsorb salts glucose and water

5

What for the kidneys do

Excrete waste products and regulate water potential of blood
