Venous drainage flows directly into the inferior vena cava on the right side and into the left renal vein on the left side. Lymphatics drain medially to the aoic nodes. Each adrenal gland is composed of two distinct pas: the adrenal coex and the adrenal medulla. The coex is divided into three zones. Ref - BDC 6e vol2 pg328
