Misconceptions
Digestion |
|
- • Misconceptions and naïve conceptions of throat
- • There is only one tube at the throat level
- • Just recognize there is a tube of some sort connecting the throat and the next part of the digestive system.
- • Believe there is only one tube and the food and the air go together.
- • Believe there is one tube and a flap of skin that does something but unsure of its role.
- • Only a very few students have the idea of a flap of skin, known as epiglottis, that directs the food in one direction and the air in the other.
- • there are two tubes without flap of skin
- • Confuse the placement of the digestive organs.
- • they say that intestines come before the stomach.
- • food goes to the intestine first and then the stomach.
- • Do not have many conceptions about the presence of the large intestine or its function in water absorption
- • No model of the absorption process at the small intestine
- • There is air you breathe in the stomach
- • Stomach cramps are because air is present in the stomach.
- • Fat is transported to the stomach where it burns forming energy and then sends that energy to the rest of the body
- • Small food particles actually travel to all parts of the body where they are then turned into energy
