INVERTEBRATE DIGESTIVE SYSTEMS
DANIEL PINZON-SEBASTIAN DIAZ
Animals have developed different types of digestive systems to break down the different types of food they consume. Invertebrates can be classified into those that use intracellular and extracellular digestion.
INTRACELULAR
The ingested material enters the mouth and passes through a tube. The food particles are engulfed by the cells lining the gastrovascular canal and the molecule is broken down within the cytoplasm of the cells.
EXTRACELULAR
When food passes into the intestine, nutrients are absorbed. As the food has been broken down on the outside of the cells, the material that the organism cannot digest is eliminated as feces, called excrement, through the anus. Most invertebrates use some form of extracellular digestion to break down their food.
QUESTIONS
- How the ingested material enter?
- How Is clasificated the digestion of animals AND explain?
- How aré nutrientes absorb when we talk about extracelular?
¡Eureka!
¡THANKS!
