Answer 1

The body does not excrete oxygen.

• Oxygen enters the lungs and exchange of carbon dioxide and oxygen takes place within the alveoli of lungs. Therefore, carbon dioxide gets released from the body.
• The body loses water as it excretes in the form of urine after blood filtration takes place in the kidneys.
• Most of the uric acid gets filtered and removed through the urine.
• Sweat is also a medium by which the body releases water and other minerals.
• Waste products, either nitrogenous or non-nitrogenous get excreted from the body via kidneys or other ways.
