After learning about several of the body systems, Jon tells the class that the digestive system and respiratory system have one

Valentin [98]

The correct answer is option D, that is, Jon is correct because the respiratory system removes waste from the body by ridding it of carbon dioxide when we exhale, and the digestive system removes waste from the body in the large intestine where the waste is sent and removed through the rectum.

The respiratory system functions to provide adequate oxygen for the proper functioning of the body and at the same time works to remove the waste products like carbon dioxide via the process of exhalation.

On the other hand, the function of the digestive system is digestion and absorption. It digests the food components into smaller pieces, and helps in the absorption of nutrients from the food, the leftover undigested food, or waste is excreted out through the rectum. Hence, both respiratory and digestive system exhibits one common function of excretion of waste materials.
