Document Summary
Regulate the bloods volume and chemical maintains the proper balance between water and salts and acids and bases. They produce enzymes (renin) and help regulate blood pressure. Their horomne erthropoietin stimulates red blood cell production in bone marrow. Kidney cells convert vitamin d to its active form. Lie against the dorsal body wall in a retroperitoneal position (beneath the parietal peritoneum) in the superior lumbar region. Kidneys go from t12 to the l3 vertebra. Renal fascia anchors kidney and adrenal gland to surrounding tissues. The outer region is called the renal cortex. Next is the renal medulla which has triangular regions with a stripped appearance called the renal or medullary pyramids. The pyramids are separated by extensions of cortex like tissue, the renal columns. Lateral to the hilum is the renal pelvis. The pelvis is continuous with the ureter leaving the hilum. Extensions of the pelvis, calyces form cup shaped areas that enclose the tips of the pyramids.
