Renal disorders Glomerular filtration rate (GFR) = _125 mlminute, but 124 mlmin is absorbed. o 1 ml excreted = 60 mlhour Antidiuretic hormone (ADH): water _absorbed_ from urine into blood = water retention. ReninAngiotensinAldosterone Pathway (RAAS): NA K ATPase turns on in the distal tubule. + 1. NA H 2 reabsorbed ( blood voldoesnt change blood osmolarity) 2. K secreted (K blood levels ) Glomerular dysfunction named via _tissue_ appearance 1. Proliferative = inflammatory 2. Membranous = thickening of capillary 3. Sclerosis = tissue Glomerular nephritis (Acute Nephritic Syndrome) via strep A (most common), chicken pox, mumps, or measles. 1. Causes edema, hypertension, proteinuria, and hematuria. 2. Coca cola_ urine (dark brownreddish color), increased BUN (azotemia). o BUN = Blood Urea Nitrogen; tests nitrogen waste in bloodused for testing kidney function. Goodpastures Syndrome: _autoantibody_ formation that causes destruction and increased porosity of glomerular basement membrane.
