MORPHOLOGICAL FEATURES OF THE LYMPHOID STRUCTURE OF THE COLON AND IT’S IN WHITE RATS IN THE DYNAMICS OF AGE

Abstract

The immune system largely depends on age, health, stress, environmental conditions and other factors. The study found that the length of the colon of rats of intact and irradiated groups showed that there was a decrease in its length, which is most pronounced at 3 months of age, in the following months of observation, these indicators were at almost the same level. Thus, studies have shown that the morphometric parameters of the colon (length, perimeter, thickness) increase unevenly with age.
