Bob eats his breakfast, and his GI tract will now begin the process of digesting and absorbing the nutrients from this meal. What is the order in which each of the organs of the GI tract will work to achieve this process?

mouth-oesophagus- stomach- small intestine-large intestine

Explanation:

Digestion can be defined as the process in which large food particles are broken down into smaller particles.

Digestion begins in the mouth, the teeth helps to break down the large food particles into smaller one, this process is known as mechanical digestion. After this process the saliva secretes an enzyme called ptyalin which further breaks down the food into simpler forms that can be absorbed by the body.

The food food then passes through a long muscular tube known as the oesophagus to the stomach through a series of contractions called peristalsis.

The stomach is a sac like organ, here the food particles are crushed and grinded into more simpler forms. The stomach secretes enzymes that further break down the food particles. The food particles then moved to the small intestine.

The small intestine is made up of three segments; the duodenum, jejunum and ileum. The food particles is further broken down by enzymes released by the pancreas and bile released by the liver. The duodenum is responsible for further breaking of the food while the jejunum and ileum absorb nutrients from the food into the blood stream.

The remaining liquid food particles from the small intestines then moved into the large intestine where it is converted into a solid form by the colon and then secreted out of the body.
