NURS 220 Lecture Notes - Lecture 27: Renal Function, Distal Convoluted Tubule, Proximal Tubule
Document Summary
Control of fluid, electrolyte and acid base balance. Renin-used to increase map, part of electrolyte balance system. External covering- a) b) c) d) renal fascia-tough connective tissue (lots of collagen) wrapped around fat. adipose capsule-fatty layer of padding/protection renal capsule-clings to kidney hilus-opening where blood vessels go in and out and where ureters go out. Internal anatomy- a) renal cortex-outer aspect b) c) d) renal medulla-inner portion major and minor calyces-tubes of medulla drain into these calyces (minor calyces drain into major calyces) renal pelvis-calyces drain into the renal pelvis. Blood supply-kidneys get 25% of blood under resting conditions (about 1 liter per minute). Go behind bladder and enter into a position in the back. Bladder-houses urine until it is excreted via urethra (storage area) Smooth and skeletal muscle control of emptying of bladder. Parts-form urine between interaction of blood and a tube a) Net filtration from the blood to the tubule.
