| as completely and specifically as possible, describe the physiological events that take place when a human consumes food from mastication to defecation | Mastication is chewing and it takes place in the mouth. After mastication, deglutition takes place, which is swallowing, and it happens in the esophagus. Bolus is the food mass where food and saliva mix and also takes place in the esophagus... |
| continue 2 | Peristalsis is when voluntary smooth muscles contracts food mass from the mouth to the stomach to the anus. Gastroesophageal valve is a valve that is located on the top of the stomach, and it regulates how much bolus gets into the stomach.... |
| continue 3 | Chyme is when the food mass bolus gets into the stomach, it becomes chyme and located in the stomach. Hydrochloric acid has a pH of 2, located in the stomach and is a strong acid. |
| continue 4 | Pepsin is located in the stomach, and it is enzyme that initiates digestion of proteins. Pyloric Sphincter regulates the amount of chyme that leaves the stomach and goes into the small intestine and it's also a valve. |
| continue 5 | The small intestine is the duodenum, jejunum, and ileum which absorbs more nutrients. Villi are fingerlike projections that extends lines inner wall of small intestine that increase surface like. |
| continue 6 | Ileocecal valve regulates the amount of chyme leaving the small intestine and entering into the large intestine, and it's located on the last part of the small intestine (ileum) and the first part of the large intestine (cecum). |
| continue 7 | Large intestine is when the chyme leaves the small intestine and goes into the large intestine which becomes a fecal matter. The fecal matter is when it gets to the anus which eliminates solid waste. |
| continue 8 | Then defecation is the feces that comes out from the anus. The defecation usually happens in the last part of the large intestine which is the rectum. |
