A
Chyme
B
appendix
C
bile
D
peristalsis
Explanation: 

Detailed explanation-1: -Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. It starts in the esophagus where strong wave-like motions of the smooth muscle move balls of swallowed food to the stomach.

Detailed explanation-2: -A series of normal coordinated, rhythmic muscle contractions, that occurs automatically to move food through the digestive tract is called peristalsis.

Detailed explanation-3: -This sense of direction might be attributable to the polarisation of the myenteric plexus. Because of the reliance of the peristaltic reflex on the myenteric plexus, it is also referred to as the myenteric reflex.

Detailed explanation-4: -Alternating contraction and relaxation of these muscles is called peristalsis. Peristaltic waves push the swallowed bolus down the esophagus. In the stomach, peristalsis churns swallowed food, mixing it with gastric juices. These mechanical and chemical actions further break down food into a substance called chyme.

Detailed explanation-5: -Primary esophageal peristalsis. Secondary esophageal peristalsis. Tertiary esophageal peristalsis.
