to move food through the digestive system


B)
to remove excess liquid from the body


C)
to chemically digest food to release nutrients


D)
to absorb nutrients into the blood

Respuesta :

Answer:  A

Explanation

The digestive tract carries out the function of peristalsis by moving food through the system.  Peristalsis also removes excess liquid from the body.  Chemical digestion breaks down food into small nutrients, but this process does not involve peristalsis.  Finally, absorption of nutrients into the blood does not fall under the purview of peristalsis.

A
It is the wave like contractions and relaxation of the gullet to pull down food into the stomach
