Explanation:

• For question 2: The urethra is the tube that transports urine out of the body. In males, it also has a role in the reproductive system for semen transport, but in the context of excreting urine, it's the urethra.
• For question 3: The skin is the largest organ. It excretes sweat (perspiration) which contains water, salts, and small amounts of urea. It also helps in thermoregulation by excreting heat (through processes like vasodilation and sweating).
• For question 4: The lungs excrete carbon dioxide. During cellular respiration, cells produce carbon dioxide as a waste product. The blood transports this carbon dioxide to the lungs, and during exhalation, the lungs expel it from the body.

Answer:

1. Urethra
2. Skin
3. Carbon dioxide
