The large intestine of the alimentary canal or digestive system absorbs water  from the remaining indigestible food matter and transmit the useless waste material from the body. 

The urinary system includes the kidneys. The kidneys filter out and reabsorb nutrients such as glucose and electrolytes, while allowing waste products such as  salts, some amino acids, ammonia and byproducts  of bile to be excreted from the body as urine.

The lungs, part of the respiratory system expel carbon dioxide  from the body as  a waste byproduct of respiration.

Waste (feces) of the  digestive system is from food we eat.

Urine is principally made of water that we drink.

Carbon dioxide is a  waste byproduct of  cellular respiration in our bodies that is  fueled by the oxygen we breathe in.
