Question

select all that apply select all of the following that apply to peristalsis. propels food in two directions stimulated by autonomic nervous system helps to churn food, along with enzymes wavelike contractions of smooth muscle forceful contractions of skeletal muscle

Explanation:

Peristalsis is the wavelike contractions of smooth muscle in the digestive tract, stimulated by the autonomic nervous system, which propels food in one direction (from mouth to anus), not two. It helps move food along rather than primarily churn it (churning is more associated with stomach - specific movements like segmentation). It involves smooth muscle, not skeletal muscle.

Answer:

• stimulated by autonomic nervous system
• wavelike contractions of smooth muscle
