Explanation:

In the case of the respiratory system the major materials moving through it are oxygen and the waste product carbon dioxide. The digestive and respiratory system share some common spaces. The digestive system is composed of the mouth, pharynx, esophagus, stomach, small intestine, large intestine, rectum and anus.

Answer 2

The respiratory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history

The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.
