Digestion | is the process by which food is broken down into small nutrients |
Mechanical Digestion | the physical break down of food by chewing or churning |
Chemical Digestion | the chemical break down of food by enzymes produced by pancreas and liver |
Mouth | Carbohydrates start to get broken down into simple sugars. Using chewing and grinding and enzymes in saliva break down starch into sugar |
Amylase | Enzymes that digests carbohydrates = protein |
Epiglottis | is a flap that makes sure the food does not go down into the lungs |
Esophagus | a tube that connects the mouth to the stomach, peristalsis occurs here |
Peristalisis | the rhythmic contraction of muscles that push food through the digestive system |
Stomach | muscular organ that starts the digestion of proteins with pepsin and hydrochloride acid |
Pepsin | helps break down protein it is an enzyme |
Liver | produces bile, which breaks down fat into small pieces |
Gallbladder | stores the bile |
Bile | stored until released into small intestine also breaks down fats into tiny particles |
Pancreas | produces insulin to break down sugar |
Insulin | break down sugars |
Small intestine | most chemical digestion is completed and nutrients are adsorbed digestion gets completed here |
Villi | help absorb nutrients and increases the surface area and are finger like projection |
Large intestine | removes water and vitamins to for solid waste |
Rectum | stores solid waste products |
Enzymes | proteins and fits like a lock and a key |
