BIOL302 Lecture Notes - Simple Squamous Epithelium, Renal Corpuscle, Distal Convoluted Tubule
Document Summary
Consists of renal corpuscles (glomerulus and bowman"s capsule) for filtering. Medullary rays break up the cortex into segments: medulla. Pyramidal areas that tubules and blood vessels pointing in one direction that empty into the papilla. Outer, more dense, darker layer consists of proximal and distal tubules. Inner, looser lighter layer consists of loop of henle, collecting ducts, papillary ducts. Lobes are defined as a pyramidal shape calyxes at the small end of the pyramid join to form the renal pelvis. The renal artery and renal vein supply blood to the kidney. Nephron is the functional unit of the kidney. The glomeruli and the tubular system are both parts of the functional unit. It consists of the renal corpuscle, proximal convoluted tubule, loop of henle, and distal convoluted tubule. The uriniferous tubule is divided into the proximal tubule, the intermediate (thin) tubule, the distal tubule and the collecting duct. Vascular pole: blood supply, big afferent arteriole, glomerulus, small efferent arteriole.
