DIGESTIVE SYSTEM

MAIN FUNCTIONS

The digestive system has three main functions

  • Digestion: break down of foods in to simpler forms which can be absorbed by the body cells 
  • Absortion: nutrients form digested food absorbed in to the blood stream 
  • Elimination: forming, storing and elimination of solid wastes 
PARTS

The main parts are:
  • Mouth: mastication or chewing is the first step digestion. Chewing increases the surface area of foods to allow more efficent break down .
  • Esophagus: connect the mouth to the stomach 
  • Stomach: the acids in the stomach break down the long chains of food (as proteins)
  • Liver the liver is an organ that remove the toxic subtances from the body. 
  • Small intestine: It is where most of the absorption of food takes place.
  • Large intestine : It is where the water is absorbed and the feces are before being removed.
  • Anus: Its function is to contro the feces removal
RELATIONSHIP WITH OTHER SYSTEMS 
  • Circulatory system : Provides the nutrients to the blood used in the body processes.
  • Excretory system: The excretory system helps the digestive to getting rid of waste subtances.
ILLNESSES THAT CAN AFFECT TO THE DIGESTIVE SYSTEM
  • Gastritis: It is caused by bacterial infection. Gastritis can cause vomiting, diarrhea and abdominal pain.
  • Reflux: It is the abnormal flux of the stomach contents (including acids) to the esophagus
