Document Summary
Anatomy of the kidneys-know all this stuff to up to end of first table. Renal hilium: indent where ureter emerges along with blood vessels, lymphatic vessels and nerves. Layers of tissue: renal capsule-deep layer, continuous with outer coat of ureter, barrier against trauma, maintains kidney shape. Adipose capsule-mass of fatty tissue that protects kidney from trauma and holds it in place. Renal fascia-superficial layer-thin layer of connective tissue that anchors kidney to surrounding structures and abdominal wall. Renal columns-portions of the cortex that extend between renal pyramids. Several cone shaped renal pyramids- base faces cortex, renal papilla points toward hilium. Renal lobe-renal pyramid, overlying cortex area, and of each adjacent renal column. Parenchyma: functional portion of kidney, in renal cortex and renal pyramids of medulla. The nephron is the functional unit of the kidney. Nephron waste flow: collecting duct papillary duct minor calyx major calyx renal pelvis ureter urinary bladder.
