1 Answer
Digestive system has a gastrointestinal tract and some associated glands.
Explanation:
In human gastrointestinal tract starts in mouth , leading to oral cavity . There are teeth on both the jaws, and a tongue inside oral cavity.
Oral cavity leads to a common chamber for the passage of both air and food, called pharynx .
Food pipe or oesophagus open in pharynx and swallowed food can travel to stomach through this.
Stomach is a digestive sac which opens in small intestine,
Small intestine is divided in three parts duodenum, jejunum and ileum . Both digestion and absorption take place here.
Then there is large intestine , divided in caecum, colon and rectum .
Rectum opens outside by anal opening .
Salivary glands are three paired structures, namely
submaxillary, sublingual, and parotid .
Then there are two large abdominal glands helping in digestion of food: these are liver and pancreas .
