The mucosa of the small intestine contains four major cells types including absorptive cells‚ which produce digestive enzymes and absorb digested fats‚ the goblet cells‚ which produce protective mucus‚ granular cells‚ which may help protect the intestinal epithelium from bacteria; and endocrine cells‚ which produce regulatory hormones. The small intestine contains

such as hormones‚ enzymes‚ and waste products. Lipid absorption. Lymphatic vessels such as lacteals in the intestines absorb and transport large molecules‚ fats‚ and lipids in the digestive system mainly in the form of lipoprotein such as chylomicrons. The lymphatic system absorbs lipids and other substances from the digestive tract through lymphatic vessels called lacteals located in the lining of the small intestine. Lipids enter the lacteals and pass through the lymphatic vessels to the venous circulation

Metabolites through the body Food that we consume is composed of very complex molecules. During the digestive process these compounds are broken down into smaller and smaller subunits in preparation for use by the body as building blocks needed for the many components of the human body.

First the Homo sapien will be insert the food into its alimentary canal. It will then chew the food creating a bolus of food‚ which is caused by the enzymes in the saliva which break down the food making it ready for swallowing or deglutition. The bolus of food goes through the larynx‚ which is the hollow muscular organ forming an air passage to the lungs and holding the vocal cords in humans and other mammals. The bolus of food passes through the oesophagus. The oesophagus is a muscular tube which

days ANALYSIS: The Digestive System- THE MOUTH: 1. Teeth: Pigs teeth have to be sharp and pointed so they can chew their food well so it can be transferred to the stomach. Hard Palate: The hard palate has to be hard and rippled so they food can be broke down easier‚ while it’s being chewed it will hit the hard palate and break down easier. Tongue: It’s supplied with a number of muscular valves. That control and direct the amounts of food through the Digestive tract. Epiglottis: The Epiglottis
