Unappreciated until malfunctioned: contaminated with internal garbage. Location located in upper portion of lumbar region abdominal cavity between muscles of posterior wall and membrane of peritoneum of peritoneal cavity. Medial surface is concave: has cleft = hilus. Where renal artery enters artery and renal vein leaves all passageway. Gross anatomy: surface anatomy: lateral suface is smooth. Dense irregular connective tissue anchors kidney to surrounding structures. I nternal anatomy: cortex, medulla, pelvis cortex: outermost layer, in contact with renal capsule. Medulla: middle layer, medulla or renal pyramids: cone shaped masses of tissue. Base faces cortex apex faces renal sinus. Minor calyx: branching of major calyx, acts as a catching cup of urine for each papilla. Urine flows from major calyx to pelvis, travels down ureter.
