Document Summary

Kidneys are very vascular organs that receive 1/4 of cardiac output internal structure. Cortex, arcuate vessels, medulla (renal pyramid), papilla, calyces and renal pelvis, renal sinus outer cortex inner medulla (made of renal pyramids) Lecture #20 - the urinary system: segmental arteries, interlobar arteries, arcuate arteries, interlobular arteries, afferent arterioles, glomerulus, efferent arterioles, peritubular network, vasa recta. Lecture #20 - the urinary system afferent arteriole = big efferent arteriole = small. Bowman"s capsule (glomerular capsule: cortical and medullary tubular system structural definition of a nephron. A renal tubule composed of 2 coiled segments (separated by a simple u shaped tube) At proximal end, tubule forms a cup shaped chamber (bowman"s capsule) that surrounds the glomerulus and at its distal end it connects with the collecting duct. Tubular and collecting system: bowman"s capsule, proximal convoluted tubule, proximal straight tubule, thin limb of loop of henle, distal straight tubule, distal convoluted tubule, collecting ducts (medullary rays, papillary ducts.
