This handwritten flowchart summarizes the human digestive system. Digestion begins in the mouth, where mastication and salivary amylase start breaking down food to form a bolus. Food passes through the pharynx and esophagus by peristalsis into the stomach, where hydrochloric acid, pepsin, and mucus aid protein digestion. In the small intestine, bile and pancreatic juice continue digestion, while nutrients are absorbed through villi and microvilli. The large intestine absorbs water, and waste is expelled through the rectum and anus.#bloodtypehealth #nursing #studynotes #medlife #medstudent
