Nephron/Kidney Regions(Matching) Flashcards
PCT
Does the most modifying by reabsorption and some secretion
Glomerular capsule
Double-walled epithelium and specialized spherical capillary bed that captures filtrate
Descending loop
Modifies filtrate; reabsorbs H2O
Ascending loop
Modifies filtrate; reabsorbs Na+ and Cl-
DCT
Modifies filtrate with some secretion and variable reabsorption due to hormones
Renal corpuscle
Cup where blood is filtered from capillaries
Glomerulus
Fenestrated capillary network
Juxtaglomerular apparatus
Cluster of adjacent smooth muscle and DCT cells that secrete renin and EPO
Renal tubule
Passageway for filtrate
Loop of Henle
Reabsorbs only salt and H2O
Collecting duct
Tube that drains many nephrons; continues H2O reabsorption and variable ions
Renal fascia
Anchors and supports
Adipose capsule
Protection
Renal capsule
Maintains shape
Minor calyx
Drains urine from 1 pyramid
Major calyx
Drains urine from 2+ pyramids
Renal pelvis
Collects all urine
Ureter
Paired tubes that carry urine from kidneys to the bladder
Juxtaglomerular complex
Macula densa and Juxtaglomerular cells
Macula densa
Simple cuboidal cells of DCT
Juxtaglomerular cells
SM cells between arterioles; respond to blood O2 and pressure and send a messenger to DCT to secrete EPO and renin
