The document discusses the human digestive and respiratory systems. It describes the four main processes involved in nutrition: digestive, respiratory, excretory, and circulatory. The digestive system begins with ingestion in the mouth through chewing by teeth and mixing with saliva. Food then passes to the stomach through the esophagus and is further digested. In the small intestine, nutrients are broken down and absorbed into the bloodstream. The liver plays an important role in processing nutrients and filtering the blood. Undigested waste is eliminated through the large intestine and anus. Respiration provides oxygen for cellular respiration through an exchange of gases in the alveoli of the lungs.
