Question

The digestive system is composed of two parts: the alimentary canal and the accessory digestive structures. These two parts of the system work together to break down food into absorbable units and eliminate the non-digested material as feces. Let's begin by identifying each of the organs in the alimentary canal and the accessory digestive structures. Don't be a digestive hog -- just choose one organ/structure and post details about it -- then the rest of us have something to talk about during these posts

Explanation / Answer

The digestive system starts from mouth and ends in anal canalincluding anus.

It consists of mouth (including tongue, teeth), pharynx (oropharynx, pharyngopharynx), epiglttis, esophagus, stomach, small intestine (duodenum, jejunum, ileum), large intestine (cecum, colon - ascending, transverse, descending, sigmoid), rectum, anal canal.

The accessory digestive structures include salivary gland, liver, gall bladder, pancreas.

The liver located just below diphragm, mostly on the right side secretes bile, thereby excreting lipid-soluble waste products, that can not be excreted through urine. It produces bile, that contains bile salts, essential for assimilation of fat and fat-soluble vitamins. All thhe assimilated food first passes through the liver, through portal circulation, to be metabolized by the liver.
