Digestive system:

is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract Digestive system

Why is digestion important?:

Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body. The body breaks down nutrients from food and drink into carbohydrates, protein, fats, and vitamins. Why is digestion important?


Mouth The mouth is where the digestive tract begins. Enzymes released into the mouth start the process of digestion. Gallbladder The gallbladder is a small pouch that stores bile. The gallbladder release bile into the duodenum to help digest fats in the food you eat . Small Intestine The small intestine is called small because of its width, not its length. It's actually much longer than the large intestine. The small and large intestines form one continuous tube . Appendix The appendix is attached to the cecum. If it becomes inflamed, this is called appendicitis.


Pharynx Because both food and air move through it, the pharynx is part of both the respiratory and digestive systems . Esophagus The esophagus is a soft, muscular tube that moves food from the pharynx to the stomach . Liver The liver is the body's largest internal organ. The liver performs many tasks, including storing energy and helping the body get rid of toxins . Stomach The stomach has a tough lining ─ it's able to hold up in the highly acidic environment needed to break down food.


Pancreas The pancreas makes hormones (including insulin) to regulate the blood glucose level. It also makes enzymes that break down food in the intestines . Large Intestine The large intestine consists of three parts – the cecum, the colon, and the rectum . Anus The anus marks the exit point of the digestive tract; it's where poop leaves the body.
