Renal Physiology Flashcards
RBCs waste product is bilirubin, while for muscles it is?
Creatinine
If urea is the waste product of proteins, then the waste product of purines will be?
Uric acid
Location of the kidney
T12-L3 - weighing about 150g
Most vascularized part of the kidney
Cortex
Functional unit of the kidney
Nephron
Only capillaries of the body that leads to arterioles and not venules
Glomerular capillaries - responsible for the GFR
Secrets Erythropoietin (EPO)
Interstitial cells of peritubular capillaries
Hairpin loop-shaped peritubular capillaries of the juxtaglomerular nephrons that participate in countercurrent exchange
Vasa recta
Capacity of the bladder
600ml
Urge to urinate
150ml
Bladder muscle
Detrusor muscle
Type of nephron located at the corticomedullary junction with vasa recta and long loops of Henle
Juxtamedullary nephrons
Parts of the nephron
Renal corpuscle
Renal tubular system
Capillary endothelium of the renal corpuscles secretes?
Nitric oxide and endothelin - 1
Final filtration with filtration slit diaphragm
Podocytes
Found in between capillaries, involved in glomerular diseases
Mesangial cells
Secretes Renin
JG cells - glomerular cells of the afferent arterioles found at the walls of the afferent arterioles
Found at the distal convoluted tubule, monitor sodium concentration in the DT
Macula densa
Macula densa is located at?
Early distal tubule or First part of the Distal Tubule
Refers to the movement from glomerular capillaries to Bowman’s space
Filtration
Refers to movement from peritubular capillaries to interstitium to Tubules
Secretion (tubular)
Refers to movement from tubules to interstitium to peritubular capillaries
Reabsorption
Estimates GFR
Inulin, creatinine
Refer to Renal plasma/ blood flow parameter
PAH
