Which of the following functions as part of the excretory and respiratory systems?
Answers
Answer:
The Lungs.
Explanation:
The lungs are part of the respiratory system as well as organs of excretion. They are responsible for the excretion of gaseous wastes from the body.
The organs of your excretory system help to release wastes from the body. e.g) your lungs are part of the respiratory system. They remove carbon dioxide from your body hence they are also part of the excretory system.N:B- Excretion cleans up after respiration. Respiration is a chemical reaction that takes glucose (sugar) and oxygen to produce energy. But it also produces water and carbon dioxide as bi-products. Excretion gets rid of carbon dioxide, water, and other, possibly harmful, substances from your body.
