5] Succus entericus also called intestinal juice is a fluid secreted in the small intestine in small quantities .

Succus entericus is the alkaline secretion produced by glands in the duodenum wall, which consists of water, mucoproteins, and carbonate hydrogen ions .

FUNCTION :-

This intestinal juice is formed by the secretions of the mucosal brush boundary cells along with the secretions of goblet cells .

It helps counteract the highly acidic and proteolytic chyme entering from the stomach into the small intestine, and thus protects the duodenum against damage .

• Stomach :-

✍️ Secretes Proteases .

8] Peristalsis is a series of wave-like muscle contractions that moves food to different processing stations in the digestive tract .

☞ Along with segmentation or mixing of food, peristalsis is an essential part of providing the body with nutrients .
