We should always take note the foods that are healthy from what are not healthy. So when choosing food to eat, what should you do then? VI. Lesson ProperThe function of the gastrointestinal system is to breakdown food for absorption into the body.This process occurs in five main phases namely: ingestion, fragmentation,digestion, absorption, and elimination of waste products.Ingestion is the process of consuming food and taking it into the body.Fragmentation is separating food into fine particles. Digestion is the process by which food is enzymatically broken down into molecules that are small enough to be absorbed into the circulation. Absorption is the process of assimilating substances into cells or across the tissues and organs through diffusion or osmosis. Lastly, the discharge of waste matter from the large intestine.Food is propelled along the gastrointestinal tract by two main mechanisms: voluntary muscular action in the oral cavity, pharynx, and peristalsis in the upper third of the oesophagus. Peristalsis is the involuntary waves of smooth muscle contraction.From the esophagus to the anus, the digestive is basically a tube very similar to other tubular organs in the body.  The gastrointestinal tract has four distinct functional layer: mucosa, submucosa, muscularis propria, and adventitia.The mucosa is made up of three components: the epithelium, a supporting...
