Changes in the mucosa of the small intestine in white rats in the process of digestion

Morphological and morphometric studies of the small intestine of albino rats have shown that its villi undergo cyclic changes. These changes involve the death, growth and maturation of the villi. Digestion intensifies proliferative processes in the small intestinal mucosa. The data obtained support the conception that the death of the villi is a morphological expression of secretion (excretion) and absorption in the small intestine.
