How do the lungs work?

The lungs and breathing are the main part of the respiratory system, which is used for breathing. Fresh air comes in through the mouth, down the trachea ( the windpipe), into the lungs through cartilaginous pathways called bronchi and bronchioles, where it is absorbed by tiny air sacs called alveoli. The lungs take in oxygen and get rid of carbon dioxide.

The parts of the digestive system and their functions

The parts of the digestive system are: The mouth is the beginning of the digestive tract; and, in fact, digestion starts here when taking the first bite of food. Chewing breaks the food into pieces that are more easily digested. Esophagus Located in your throat near your trachea (windpipe), the esophagus receives food from your mouth when you swallow. The Stomach holds food while it is being mixed with enzymes that continue the process of breaking down food into a usable form. The small intestine is a 22-foot long muscular tube that breaks down food using enzymes released by the pancreas and bile from the liver. The pancreas secretes digestive enzymes into the duodenum. The Liver function within the digestive system is to process the nutrients absorbed from the small intestine. The gallbladder stores and concentrates bile. he colon is a 6-foot long muscular tube that connects the small intestine to the rectum. Rectum to get rid of wastes. The relationship bettween Cellular and digestive system is the Glucose is oxidized with oxygen during cellular respiration to provide energy

and to form words in speech. It can also assist the respiratory system in the passage of air. The Mouth has a cord after it for the food that has been chewed to continue to the rest of the Digestion system it is called the esophagus. The mouth is where mechanical and chemical digestions begins.
