Day 1 Reflection

Today,I found that the Digestive System consists of

Mouth
Esophagus
Stomach
Large Intestine
Small Intestine
Anus and Rectum

Mouth

The mouth is the beginning of the digestive tract; and, in fact, digestion starts here when taking the first bite of food. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use.


Esophagus

The esophagus is a straight muscular tube that contains the four basic layers common to the rest of the digestive tract. Its function is to carry food,liquids and saliva from the mouth to the Stomach.

Stomach

The stomach is an organ in which acid secretions and digestive enzymes contribute to the digestion of food. It is an hollow organ which composes of several strong muscular layers. It is protected under the rib cage and is connected at at each opening to the Esophagus and Small Intestine. The stomach also stores,mixes and digests the food we eat.

Small Intestine

The Small Intestine is made up of a number of parts in which,all plays a part in Digestion. Food first enters your mouth, then goes down your esophagus into the stomach. After leaving the stomach,it enters the small intestine then the Large intestine, then out of the body.

Large Intestine

The large intestine is the part of the digestive system where waste products from the food you eat are collected and processed into faeces. It reabsorbs water and maintains the fluid balance of the body and absorbs certain vitamins.

Rectum and anus

Faeces is then released from the anus when Digestion is complete.
