Explanation:

The largest organ in the human body that excretes heat and perspiration is the skin. The skin has sweat glands which produce sweat (perspiration). When sweat evaporates from the skin's surface, it helps in cooling the body (excreting heat). For the lungs, during respiration, they take in oxygen and release carbon dioxide. So, the lungs excrete carbon dioxide as a waste product.

Answer:

1. Skin
2. Carbon dioxide
