EXCRETORY SYSTEM

3 FUNCTIONS OF THE EXCRETORY SYSTEM REMOVES WASTES FROM YOUR BLOOD. MAINTAINS THE pH OF YOUR BLOOD. REGULATES THE AMOUNT OF WATER IN YOUR BLOOD.

WASTE REMOVED BY EXCRETORY SYTEM METABOLIC WASTES THAT ARE MADE WHEN THE CELLS PERFORM THEIR JOBS.

PARTS OF THE EXCRETORY SYSTEM KIDNEYS URETERS BLADDER URETHRA

KIDNEYS PAIR OF ORGANS IN THE ABDOMINAL AREA. THEY ARE USED TO FILTER BLOOD AND PRODUCE URINE.

UREA WASTE PRODUCT OF BLOOD MADE FROM PROTEIN DIGESTION.

WASTE PRODUCTS BESIDES UREA, SALT IS ALSO A WASTE PRODUCT.

URINE FORMED IN THE KIDNEYS CONSISTS MOSTLY OF WATER BUT ALSO CONTAINS UREA, SALT, AND OTHER WASTES.

URETERS TUBES THAT CARRY URINE TO THE BLADDER FROM THE KIDNEYS.

BLADDER STORAGE FOR URINE AN AVERAGE ADULT BLADDER CAN HOLD ABOUT CUPS OF URINE

URETHRA THE TUBE URINE IS EXPELLED THROUGH

NEPHRONS TINY FILTRATION UNITS INSIDE THE KIDNEYS THEY FILTER IMPURITIES OUT OF THE BLOOD AND RETURN THE PURIFIED BLOOD TO THE BODY.
