3 Filter plasma, separate and eliminate wastes Functions Regulate blood volume and pressure Regulate osmolarity of body fluids by water control Secrete enzyme renin Secrete hormone erythropoietin Acid-base balance Calcium homeostasis Detoxify using peroxisomes Gluconeogenesis: starvation
4 Proteins - - -
5 Nitrogenous Wastes Urea proteins amino acids NH 2 removed forms ammonia, liver converts to urea Uric acid nucleic acid catabolism Creatinine creatine phosphate catabolism Renal failure azotemia: BUN, nitrogenous wastes in blood uremia: toxic effects as wastes accumulate 23-5
6 Kidney Location 23-6
7 Anatomy of Kidney Renal cortex: outer 1 cm Renal medulla: renal columns, pyramids - papilla Lobe of kidney: pyramid and it s overlying cortex 23-7
8 Blood Supply Diagram 23-8

10 Nephron
11 Lobe of Kidney 23-11
12 Filtration Membrane Fenestrated endothelium 70-90nm pores exclude blood cells Basement membrane proteoglycan gel, negative charge excludes molecules > 8nm blood plasma 7% protein, glomerular filtrate 0.03% Filtration slits podocyte arms have pedicels with negatively charged filtration slits, allow particles < 3nm to pass Proteinuria hematuria 23-12
13 Nephron Diagram Peritubular capillaries shown only on right 23-13
14 Renal (Uriniferous) Tubule Proximal convoluted tubule (PCT) longest, most coiled, simple cuboidal with brush border Nephron loop - U shaped; descending and ascending limbs thick segment (simple cuboidal) initial part of descending limb and part or all of ascending limb, active transport of salts thin segment (simple squamous) very water permeable Distal convoluted tubule (DCT) cuboidal, minimal microvilli 23-14

41 Collecting Duct: Water conservation/urine concentration Water diuresis Dehydration
42 Collecting Duct Concentrates Urine Osmolarity 4x as concentrated deep in medulla Medullary portion of CD is more permeable to water than to NaCl 23-42
43 Returns salt to medulla Multiplier Recaptures salt
44
45 Composition and Properties of Urine Appearance almost colorless to deep amber; yellow color due to urochrome, from breakdown of hemoglobin (RBC s) Odor - as it stands bacteria degrade urea to ammonia Specific gravity density of urine ranges from Osmolarity - (blood mosm/l) ranges from 50 mosm/l to 1,200 mosm/l in dehydrated person ph - range: , usually 6.0 Chemical composition: 95% water, 5% solutes urea, NaCl, KCl, creatinine, uric acid 23-45
46
47 Renin-Angiotensin-Aldosterone 23-47
48 Aldosterone
49 Regulation
50 Antidiuretic Hormone
51 Antidiuretic Hormone
52
53 Atrial Natriuretic Peptide
54 Parathyroid gland: calcium regulation
