The digestive system

Now I am going to talk about the digestive system. I hope you will like it.
The digestive system, with some more systems, carry out the function of nutrition. It transforms food into nutrients and it has two parts: the digestive tract and the digestive glands. 
Food goes all through the digestive tract and digestive glands release chemicals into the digestive tract to help with digestion.
The digestive tract has a tube that has two ways: the mouth and the anus.

 

The parts of the digestive system are:                                                                                                       

• The mouth: it has salivary glands that produce saliva, teeth that chew food and a tongue too that mixes food with saliva.
• The oesophagus: it transports all the food that we eat to the stomach.
• The liver: it secretes bile.
• The small intestine: it is the longest part of the digestive tract. Nutrients pass into the blood through its walls.
• The large intestine: it is the last part of the digestive system in vertebrates.
• The pancreas: it is a gland located in the abdomen.
• The stomach: here is where the food mixes with gastric juices.
• The pharynx: it connects the mouth and the oesophagus.
