Document Summary
Module 11: renal system | page 1 of 17. Renal system includes: kidneys, ureters, bladder, and urethra. Kidneys are about the size of a first: consist of an outer renal cortex, a middle renal medulla, and inner calyces that drain into the central renal pelvis which then drains into the ureter. Bowman"s capsule (where the filtration takes place) efferent arterioles peritubular capillaries and vasa recta (dense network of capillaries surrounding tubes of the nephron) interlobular vein arcuate vein interlobar vein renal vein. Module 11: renal system | page 2 of 17. Reabsorption is the movement of a substance from the lumen of the nephron back into the blood. Secretion is the movement of a substance from the blood into the lumen of the nephron. Excretion is the removal of a substance from the body. Module 11: renal system | page 3 of 17. Glomerular filtration = bulk flow of fluid (filtrate) from the blood into the glomerular capsule.
