In the following article we have provided modern data on main stages of implementation, formation as well stabilization functional activity thymus fetus different fetal development. Thus, analyzed specific features gland’s location in case children, adolescents and adults.

The criteria completion gestational term 24 weeks clearly emphasized. maturing lymphocytes appearance surface markers them division T-cells into subpopulations described. role sphere all types organism’s immune defence was explained. an endocrine function gland providing hormones, hormone-like substances, extracts organ, which their influence onto lymphoid tissue play leading hormonal homeostasis child’s organism. morphological structural components gland, functions disclosed. nature relations between It has been proved also, that full-term fetus, is a structurally functionally formed for moment birth. Moreover, under conditions physiological pregnancy epithelial are sufficiently harmoniously developed, thymocytes differentiated immunologically mature. Finally, came up conclusion, pathology childbirth can lead to impaired embryogenesis fetogenesis thymus.
