Ingestion - It is when a food enters your body via the mouth
Teeth Type - Molar is usually found at the back-side of your mouth. They are flat surface teeth and there are lots of them. Molars are usually found in the mouth of herbivores because they mostly eat grass which needs to be crush and grinded.
- Incisor is a tooth that is found on the front of the mouth they look like chisels and functions like one, it cuts grass, and it is mostly found in herbivores.
- Canines are found on carnivores they are used for ripping the meat out of animals or holding them down so the predators can disable them one, for example, is a tiger. It is a pointed tooth between the incisor and the molar and can be found in humans. It is also called the eye teeth.
Digestion - It is when food
Oesophagus - After the food is chewed it is turned into a bolus, a Latin word for ball, it is swallowed and go through the oesophagus and by the move called peristalsis a wave-like motion moves the food down the oesophagus to the stomach.
Stomach - After the ball of food went through your oesophagus it moves down the stomach it is a large plastic bag that can enlarge that can hold up litres of food. There is an acid in your stomach called Hydrochoric acid. It is really dangerous and a really low pH level, 1-2, the reason for the acid there is to dissolve food and kills germs that enter the body because of food.
Small Intestine - The small intestine is located between the stomach and the large intestine. The pH level in the intestine is usually between 7-9, neutral with a slight of alkaline, this is the part of your digestive system where the absorption of nutrients takes place. All the proteins, carbohydrates and lipids have been broken down into small soluble molecules and can be absorbed into the bloodstream.
Muscular walls of the intestines - The muscular walls of the small intestines helps food move along via peristalsis the action of waving like motion.
Villi and microvilli and thin walls of a villus- A villus is a finger-like projection in the inner wall of the small intestines and a microvillus covers the surface of the villi. These can increase the rate of absorption. The thin walls of a villus help ensure the rapid absorption into the bloodstream.
