Urinary System Flashcards
Which kidney is higher
Left kidney which is innervated by the left gonadal vein
What type of organ is the kidney
Retroperitoneal
Renal capsule layer
Most superficial
Renal fascia layer
Deep, touching kidneys
Cortex (granular appearance)
- Renal columns
- nephron: renal corpuscle, proximal convoluted tubules, distal convoluted tubules
Medulla (striated appearance)
- Renal pyramids
- medullary rays = pyramid + column
- nephron: straight tubules (henle’s loops), collecting tubules
Nephron
Function unit of the kidney
Conserved 99% back to the systemic circulation
Renal corpuscle
Bowman’s capsule + glomerulus
Function: filtration of blood
Glomerulus
Capillary network that receives blood via afferent arterioles and sends away via efferent arterioles
Bowman’s capsule
Cup shaped structure surrounding glomerulus
Parietal layer of bowman’s capsule
Outer layer of epithelial cells
Visceral layer of bowman’s capsule
Inner layer that contracts glomerulus and is formed by specialized cells know as popdocytes which limit filtration
Renal corpuscle job
Filtration
Descending limb
Resorption
Ascending limb
Secretion
