Control Of Blood Water Potential - Structure Of The Nephron Flashcards
What’s osmoregulation
The homeostatic control of the water potential of the blood
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
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
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
What for the kidneys do
Excrete waste products and regulate water potential of blood
