Kidneys and bladder

BLADDER

The bladder is an elastic and hollow organ in the small pelvis, whose function is to store urine. Together with the urethra it forms the lower urinary tract. The two ureters open laterally into the sides of the bladder. The urethra is the extension of the cervix. At this point there is the so-called bladder suppository, which seals the bladder from dorsal to the urethra and serves to preserve continence. The topographical relationship with the prostate makes the bladder suppository more prominent in men than in women. read more...

KIDNEYS

Approximately 1.2 litres of blood flow through the kidneys per minute of which about 10% is filtered out. In an average person, this equates to 180 litres of primary urine that is filtered leaving about 1 litre of urine produced each day. The degree of urinary concentration is regulated by the hormone adiuretin. This is formed in the posterior lobe of the pituitary gland. When there is a lack of liquid, the production of adiuretin is increased. This causes lower amounts of highly concentrated urine in the kidneys, as through the action of adiuretin, water is reabsorbed into the tube system. read more...
