The lingual lipase, found in saliva, plays a minor role in breaking down fat. In the stomach, the gastric lipase converts some fat into a fatty acid or diglyceride, a glycerol with only two attached fatty acids. In the small intestine, most fat is digested. The pancreas releases pancreatic lipase. This lipase converts fat to

The food that is taken in through the mouth is moistened by saliva which is a sticky fluid that binds the food particles together to create a soft mass. Saliva contains enzymes which are called amylase which digest the starch molecules into smaller molecules. When chewing food the tongue is used to move food about and manipulates it into a mass called bolus.
It moves food through and mixing it with digestive secretions from the pancreas and liver. The duodenum is mainly responsible for the continuous breaking-down process, with the jejunum and ileum mainly responsible for absorption of nutrients into the bloodstream.

d. Zach’s G.I. tract needs the substance to assist in the breakdown of food and for absorption. Epithelial cells extend into the lamina where they form secretory folds called gastric glands. Several of these glands open into the gastric pits and secretions from these glands flow into the pits. E. If Zach’s only normal digestive enzymes from his mouth, what
the anus ). Digestion begins with the mouth. The teeth are used to break down the food into smaller molecules to be passed down the oesophagus and into the stomach. The stomach is where most of the digestion takes place, this leads to the small intestine; a narrow tube for which most of the absorption of nutrients takes place. The small intestine leads to the large intestine, another tube for which absorption takes place.
How is energy supplied in the Human Body? The human body is supplied with energy from the calories present in food. One gram of carbohydrates contains four calories; one gram of protein contains four calories while one gram of fat contains nine calories. Calories facilitate all body functions such as movement, breathing and playing. The digestive system helps break down this food into small pieces, the enzymes within the digestive system breaks the protein into amino acids, fatty acids and carbohydrates into glucose.
Undigested food travels into the large intestine. Excretes non-absorbed material passed from the small intestine. Water absorption. Stores waste and house bacteria that make vitamin K. Rectum – Feces are stored in the rectum before being expelled along the anal canal. Liver – Major role in dealing with the nutrient products of food digestion.
