Introduction Components of The Urinary System:Two kidneys,two ureters, one urinary bladder and a single urethra make up the urinary system. The kidneys,as the main excretory organs,are critically important in maintaining the balance of substances required for internal constancy.The kidneys eliminate from the body a variety of metabolic products,such as urea,uric acid,and creatinine. Further the kidneys conserve or excrete water and electrolytes as required so that the internal balance of these substances will be maintained.In fact,kidney malfunction can cause severe and even fatal problems as a result of upsets in fluid and electrolyte balance

The Kidneys The kidneys are a pair of bean-shaped,reddish-brown organs. Each kidney has two extremities,two surfaces,and two borders. On medial border of the kidney there is a vertical slit,the renal hilum,which transmits the renal vessels,nerves and a part of pelvis.The renal hilum leads into a central recess named the renal sinus,which is filled with the branches of the renal artery and vein,nerves,lymphatic vessels,minor renal calices,major renal calices,renal pelvis and adipose tissue

The Kidneys The structures which pass through the renal hilum are enclosed together by the connective tissue,to form the renal pedicle.From the front backward,the order of these structures in the renal pedicle is renal vein,renal artery,renal pelvis,and from superior to inferior is the renal artery,renal vein and renal pelvis
