draw the flow chart of digestive system and explain the process
Answers
The mouth is the beginning of the digestive tract. In fact, digestion starts here as soon as you take the first bite of a meal. 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.
Throat:
Also called the pharynx, the throat is the next destination for food you've eaten. From here, food travels to the oesophagus or swallowing tube.
StomachThe stomach is a sac-like organ with strong muscular walls. In addition to holding the food, it's also a mixer and grinder. The stomach secretes acid and powerful enzymes that continue the process of breaking down the food. When it leaves the stomach, food is the consistency of a liquid or paste. From there the food moves to the small intestine

By the process of digestion, our body break down the food and liquids that we eat into smaller parts to nourish cells and provide energy.
Various steps of digestive system in are:
1. When we chew the food in mouth,the saliva that present in our mouth helps to break the food into small pieces and starts digesting carbohydrates.
2. The broken and chewed food from saliva moves through a pipe called esophagus which connect the mouth to stomach.
3. In stomach, the food is stored and this store food is further broken down by acid and powerful enzymes that present in our stomach and from stomach food moves into the small intestine.
4. Most of the nutrients are absorbed in small intestine, in here food is broken down more by enzymes which is released from the pancreas and bile from the liver. Anything which left in the small intestine moves to the large intestine which is known as colon.
5. The colon is 5-7 foot long tube which connect the small intestine to the rectum.
6. Rectum play an important role in processing waste. 36 hours are required for stool or waste to go throughout the colon and exit the rectum through anus.
