The renal (Malpighian) corpuscle contains what 5 things?
Glomerulus, Bowman’s capsule, intraglomerular mesangial cells, vascular pole, urinary pole.
Name the sequence of blood –> urine
capillary –> endothelium–>basement membrane –> visceral layer of Bowman’s capsule with podocytes, urinary space, urinary duct
What is included into the glomerular filtration apparatus?
endothelium, basement membrane, visceral layer of bowman’s capsule
glomerular filtrate is?
primary urine
What is the function of proximal tubule?
resorption of glucose, amino acids, HCO3-, Ca, water, salts and PO4- and secretion of organic acids, drugs, cation/anion
What is the function of loop of Henle?
resorption of water and salts
What is the function and one characteristic of distal tubule?
active ion transport and impermeable to water
What is involved with the collecting duct?
ADH–>water transport across wall, aldosterone –> resorption of Na, secretion of K.
What are Macula Densa cells and what do they do?
chemoreceptor in distal tubule. Detect Na in urine and pO2 in arterioles
What are juxtaglomerular cells and what do they do?
modified smooth muscle cells. Contain dense granules with stored renin; release initiates renin-angiotensin cascade.
What is the function of extraglomerular mesangium and interstitial fibroblasts
produces EPO; increases hematopoiesis.
