Digestive System Flashcards
Tounge
Used in the act of swallowing
Mouth
Teeth and tongue break up food to increase surface area and then enzymes can contact with it.
Oesophagus
It has muscles on its wall to help push the food along
Stomach
Contractions help to churn food into chyme. It kills the bacteria here too with the stomach acids.
Pancreas
Secretes hormones to control glucose levels in the blood. After eating, there is an excess amount of glucose. This gets converted into glycogen in the liver. If there is a lack of glucose in the blood, the glycogen will be converted glucose.
Rectum
Faeces is held and collects here
Anus
This is where faeces exists the body
Liver
Produces a liquid(bile) stored in gall bladder. This is bile helps break down fat.
Small intestine
The food is moved quick here. Glands in the ileum here produce more enzymes to break down food. Smaller molecules are transported through the walls and into the bloodstream. This process is called emulsification.
Large intestine
It is made up of appendix, colon and rectum. All of the indigestible food and water remains after reaching the colon. Water is absorbed into the blood and the indigestible food becomes more solid. The ‘solid’ food moves into the rectum and eventually out of the body through the body.
