We will study the digestive system in the class ahead of the lab. On the AP page, you will find both the digestive and nervous system (nervous system studying in the lab). I will go in more detail on that page. If you have a chance, please check out Professor Fink‘s videos on the digestion system. I found him to be very thorough.
The digestive system goes from the mouth to the anus. The mouth is used for mastication which is the process of chewing.. It breaks down food. It is made up of multi-layer stratified squamous.
The cells within the alimentary canal changes every three days. There are four layers of alimentary tract.
Cuatro capas del tracto digestivo
- La mucosa es la capa más interna del tracto digestivo. Está compuesta principalmente por epitelio y células mucosas. La luz intestinal es el conducto central del tracto digestivo.
- La submucosa es la segunda capa. Contiene vasos sanguíneos, nervios y vasos linfáticos. Los vasos linfáticos son los vasos linfáticos.
- A continuación, vienen dos capas de músculo.
- La capa más interna se llama fibras circulares
- Fibras longitudinales
- La serosa es la capa más externa.
- Peritoneo visceral que recubre los órganos
- Peritoneo parietal que recubre la cavidad peritoneal
Let me know if you have any questions. Thanks! Have a great day!
