STRUCTURE AND FUNCTIONS OF THE KIDNEYS

STRUCTURE AND FUNCTIONS OF THE KIDNEYS
The kidneys are organs whose functions are excretion, osmoregulation and regulation of pH.
Kidneys are located at the back of the abdominal cavity.
Each kidney receives oxygenated blood from renal artery, while deoxygenated blood leaves through the renal vein.
Urine is carried by the ureter from the kidney to the bladder, which temporarily stores it.
From the bladder, the urine is released to the outside via the urethra.
The opening from the urethra is controlled by a ring-like sphincter muscle.
