Histology of the Urinary System Flashcards
Function of the kidneys
Filter Blood
Dispose Nitrogenous Waste
Regulate balance of H20 electrolite
Contents of the Outer layer of the Renal capsuel
Lots of Collagen Fibers
Some fibroblasts
Contents of the Inner Layer of the Renal capsule
Fewer collagen
Lots of Fibroblasts
Macroscopic Structures of the Medulla
Renal Pyramids
Renal Columns
Renal Pyramids
Base faces cortex
Apex is the renal medulla
Renal Columns
In between the Pryamids
Histology of the Renal Cortex
Renal Corpuscles
Associated tubules
Histology of the Medulla
Straight tubules leading to the papilla
Collecting ducts
Vasa recta
Contents of a Renal Lobe
Renal Pyramid
Overlying Renal Cortex
Half of each adjacent renal column
Vascular Drainage to/from Kidneys
Aorta to Renal a to Segmental a to Lobar a to Interlobar a to Arcurate a to Lobular a to Interlobular a to Afferent arteriole to Glomerular capillaries to Efferent arterioles to Peritubular capillaries and Vasa recta to Interlobular v to Lobular v to Arcurate v to Interlobar v to Renal vein to IVC
Filtration of the Kidney
Fluid is squeezed of the glomerular capillary bed
Reabsorption of the kidney
Most nutrients, water, and essential ions are returned to the blood of the peritubular capillaries
Secretion of the Kidney
Moves additional undesirable molecules into tubule from blood of the peritubular capillaries
Nephron
Structural and functional unit of the kidney
Parts of the Nephron
Renal Corpuscle
Renal Tubule
Renal Corpuscle
Filtration site in the Nephron
Renal Tubule
Site of reabsorption and secretion of the Nephron
Where does a nephron drain
Collecting tubule
Collecting duct
Multiple nephrons drain into 1 collecting duct
Renal Corpuscle
Where glomerular filtration occurs
