[The order of lymphatic organs involvement in developing immune system of human fetus and its significance in perinatal pathology].
The liver, thymus, spleen, lymph nodes, palatine and pharyngeal tonsils, appendix and Peyer's patch were studied by morphological and immune methods in more than 100 human embryos of 3 to 34 weeks of development. The order of some organs development in the immune system is established. Key periods in the development of the thymus (5-12 weeks) and 18 weeks when peripheral organs enter the immune system are specified. Inherited perinatal pathology in abnormal lymphocytic composition in the organ is illustrated by the appendix.
