Document Summary
What are the functions of the urinary system: excretion. Filtration, re-absorption, secretion (formation of urine: regulation of blood volume and pressure, regulation of blood solutes, regulation of extracellular fluid ph. Excretion of protons: regulation of rbc synthesis. Synthesis of erythropoietin: regulation of vitamin d synthesis. Location: retroperitoneal on posterior abdominal wall on either side of vertebral column, lumbar vertebrae and rib cage provide protection. External anatomy: renal capsule: fibrous connective tissue; surrounds each kidney, adipose tissue: engulfs renal capsule and acts as cushioning, renal fascia: thin layer loose connective tissue. Anchors kidneys and surrounding adipose to abdominal wall: hilum: renal artery and nerves enter and renal vein and ureter exit kidneys. Open into renal sinus (cavity filled with fat and loose connective tissue) Internal anatomy: cortex: outer area, renal columns: part of cortical tissue that extends into medulla, medulla: inner area; surrounds renal sinus, renal pyramids: cone-shaped. Base is boundary between cortex and medulla.
