Human Digestion Essay

The salivary glands are the 1st to react in the digestive process, which can be usually activated by both the look or the smell of food. Food gets into the digestive system through the oral cavity where the teeth, tongue, and salivary glands help soften and tenderize the food within minutes.

The food after that becomes anything called a bolus, which will traverse the goitre, then through the esophagus, and into the abdomen. As the meals travels throughout the pharynx the epiglottis is at place to stop food coming from entering the lungs. Once the bolus enters the tummy it is separated with chemical p secretions.

The meals is partially digested within the stomach. The bolus in that case becomes chyme (a semiliquid food). Chyme usually leaves the belly during a time period of 2-6 hours. The little intestine is definitely where the majority of the digestion and nutrient ingestion takes place with the aid of secretions from the liver, gallbladder, and pancreatic. The small intestinal tract consists of three parts: the duodenum, the jejunum, as well as the ileum.

Whatever is not absorbed inside the small gut then goes in the large gut travelling throughout the sphincter. The sphincter inhibits any of the leftover food from re-entering the little intestine. The large intestine is made up of two major parts: the colon as well as the rectum. The colon helps with the ingestion of leftover water, vitamins, or minerals.

Anything remaining after this process is considered spend product (feces) and is in that case excreted from the body with the anus, which is attached to the colon. Research
