ANATOMY 403 Lecture Notes - Lecture 13: Quadratus Lumborum Muscle, Renal Vein, Renal Capsule
Document Summary
Anatomy overview: adrenal gland, kidney, superior pole (top, inferior pole (bottom, medial/lateral border, covered by a fibrous capsule, hilum, renal artery, renal vein. Renal circulation: receives ~20% of cardiac output at rests. > afferent arterioles: renal portal system, glomerular capillaries -> efferent arterioles -> peritubular capillaries, segmental veins, peritubular venules -> cortical radiate veins -> arcuate veins -> interlobar veins - > renal vein: renal vein entrapment syndrome, mesenteric artery crushes renal vain, increases venous pressure in the kidney. In glomerulus: tubular reabsorption, renal tubule, tubular secretion, renal tubule, nephron, cortical, ubiquitous, shorter nephron loops, lower gfr, juxtamedullary, less common, higher glomerular filtration rate, longer nephron loops, thin/thick limbs, vasa recta, more concentrate urine. Vi: juxtaglomerular apparatus, macula densa, juxtaglomerular cells: secrete renin, regulates renal blood flow and gfr. Diuretic: slows renal reabsorption of water via diuresis, reduces blood volume, treats hypertension, caffeine is a diuretic; inc gfr, alcohol is a diuretic; inhibits adh production.
