Lymphatic follicle (folliculus lymphaticus) - also known as a lymphoid nodule. This is a collection of lymphoid tissue consisting of B lymphocytes, T lymphocytes and dendritic cells. Lymphatic follicles are located in lymphoid organs such as lymph nodes, spleen, tonsils and Peyer's patches of the intestine.
In the lymph follicles, an immune response to antigens occurs. Here, B lymphocytes turn into plasma cells that produce antibodies. T lymphocytes activate B lymphocytes and participate in cellular immunity. B-lymphocytes also form and mature in the follicles.
Thus, lymphatic follicles play an important role in the immune system, being the site of the development and implementation of humoral and cellular immunity.
Lymphatic follicles are small formations in the lymphatic system that perform the function of protecting the body from infections and other pathogenic factors. These formations are accumulations of lymphocytes and macrophages that are capable of absorbing and destroying foreign microorganisms.
Lymphoid nodules are round or oval in shape and are located in different parts of the body. They can be found in the submandibular, cervical, axillary, inguinal and other lymph nodes. Lymphoid follicles are part of the lymphatic system and participate in its work to protect the body from infection.
In addition, lymphatic follicles may be involved in the immune response to various factors, such as allergens, toxins and other pathogens. They are able to secrete special substances that activate immune cells and help fight infections.
It is important to note that lymphatic follicles are not independent formations. They are in close connection with other elements of the lymphatic system, such as lymphatic vessels and lymphocytes, and function as part of the body's unified immune system.
Thus, lymph follicles play an important role in protecting the body from infections and other pathogens. They are clusters of lymphoid cells that are capable of secreting special substances and activating immune cells to fight infectious agents.
