Document Summary
Small animals, they have to move their body to move food particles along but they also have cilia. In large animals we rely on smooth muscles. Circular muscle causes the diameter of the small muscle to constrict and this allows for food to push along. Also have longitudinal muscles: months in between meals and when they eat they eat something that. Python : takes a lot of work to break down and a lot of nutrients to absorb is 50% of their body mass, they ingest a whole rabbit or rat as is. Don"t chew: snakes don"t maintain their guts from their food. Bottom right: in the microvilli, these are the microvilli that make up the villus, they have short microvilli and very quickly eating they increase the surface area of the microvilli. Running machinery requires a lot of support.
