renal system


Urinary system

The “urinary system” may also be called the “renal system” or “genito-urinary system” because this group of interconnected body parts process a liquid substance called urine via special organs called the kidneys.

The urinary system consists of the kidneys, ureters, urinary bladder, and urethra. The kidneys are the primary organs of the urinary system. They are the organs that filter the blood, remove the wastes, excrete the wastes in the urine, and perform the functions of the urinary system. The other components are accessory structures to eliminate the urine from the body. The paired kidneys are located between the twelfth thoracic and third lumbar vertebrae, one on each side of the vertebral column. The right kidney usually is slightly lower than the left because the liver displaces it downward. The kidneys, protected by the lower ribs, lie in shallow depressions against the posterior abdominal wall and behind the parietal peritoneum. This means they are retroperitoneal. Each kidney is held in place by connective tissue, called renal fascia, and is surrounded by a thick layer of adipose tissue, called perirenal fat, which helps to protect it. A tough, fibrous, connective tissue renal capsule closely envelopes each kidney and provides support for the soft tissue that is inside.

In the adult, each kidney is approximately 3 cm thick, 6 cm wide, and 12 cm long. It is roughly bean-shaped with an indentation, called the hilum, on the medial side. The hilum leads to a large cavity, called the renal sinus, within the kidney.

The outer, reddish region, next to the capsule, is the renal cortex. This surrounds a darker reddish-brown region called the renal medulla. The renal medulla consists of a series of renal pyramids, which appear striated because they contain straight tubular structures and blood vessels. The wide bases of the pyramids are adjacent to the cortex and the pointed ends, called renal papillae, are directed toward the centre of the kidney. Portions of the renal cortex extend into the spaces between adjacent pyramids to form renal columns. The cortex and medulla make up the parenchyma, or functional tissue, of the kidney. The central region of the kidney contains the renal pelvis, which is located in the renal sinus, and is continuous with the ureter. The renal pelvis is a large cavity that collects the urine as it is produced. Each kidney contains over a million functional units, called nephrons, in the parenchyma (cortex and medulla). A nephron has two parts: a renal corpuscle and a renal tubule.

Each ureter is a small tube, about 25 cm long, that carries urine from the renal pelvis to the urinary bladder. The wall of the ureter consists of three layers. The outer layer, the fibrous coat, is a supporting layer of fibrous connective tissue. The middle layer, the muscular coat, consists of the inner circular and outer longitudinal smooth muscle. The main function of the muscular coat is peristalsis: to propel the urine. The inner layer, the mucosa, is transitional epithelium that is continuous with the lining of the renal pelvis and the urinary bladder.

The urinary bladder is a temporary storage reservoir for urine. It is located in the pelvic cavity, posterior to the symphysis pubis, and below the parietal peritoneum. The size and shape of the urinary bladder varies with the amount of urine it contains and with the pressure it receives from surrounding organs.

The final passageway for the flow of urine is the urethra, a thin-walled tube that conveys urine from the floor of the urinary bladder to the outside. The opening to the outside is the external urethral orifice. The internal urethral sphincter surrounds the beginning of the urethra, where it leaves the urinary bladder.



Each part of the urinary system performs important functions – both for the efficient operation of the urinary system itself, and also therefore, for the body as a whole.

Functions of the kidneys: regulation of blood volume, blood pressure, the pH of the blood and the ionic composition of blood; production of red blood cells; synthesis of vitamin D; excretion of waste products and foreign substances.

Functions of the ureters: transportation of urine from the renal pelvis of the kidney to the bladder; prevention of the urine back-flow when pressure in the bladder is high during urination.

Functions of the bladder: storing urine prior to its elimination from the body; expelling urine into the urethra by a process called micturation (also known as urination)

Functions of the urethra: serving as the passageway through which urine is discharged from the body and in males the urethra also serves as the duct through which semen is ejaculated.
