Figure 10.2: Lymph Capillaries in the Tissue Spaces. This seems to be the major function of tonsils—to help children’s bodies recognize, destroy, and develop immunity to common environmental pathogens so that they will be protected in their later lives. In the small intestine, dietary triglycerides combine with other lipids and proteins, and enter the lacteals to form a milky fluid called chyle. Here we will talk about the organs. Besides the cardiovascular system, human beings have an additional type of circulatory system referred to as the lymphatic system. the lymphatic system is a network of nodes (knots of tissue) connected by vessels that drain fluid and waste products from the body. Thus, the red pulp primarily functions as a filtration system of the blood, using cells of the relatively nonspecific immune response, and white pulp is where adaptive T and B cell responses are mounted. The lymphatic system is the system of vessels, cells, and organs that carries excess fluids to the bloodstream and filters pathogens from the blood. As we learn more about the immune system though we are realizing how very important these glands are to our maintaining a sound immune system. The lymphatic system, for most people, is associated with the immune system to such a degree that the two systems are virtually indistinguishable. Figure 10.10: Mucosa-associated Lymphoid Tissue (MALT) Nodule. It drains fluid (called lymph) that has leaked from the blood vessels into the tissues and empties it back into the bloodstream via the lymph nodes. An antibody is any of the group of proteins that binds specifically to pathogen-associated molecules known as antigens. As stated above, lymphocytes are the primary cells of adaptive immune responses ([link]). The primary lymphoid organs are the bone marrow, spleen, and thymus gland. This information is not to be taken as a diagnosis, a prescription, medical advise or in any way to replace the need for a qualified primary health care professional. If you are wondering which ones, we are going to be visiting the tonsils, the thymus and the spleen. The medulla, where thymocytes migrate before leaving the thymus, contains a less dense collection of thymocytes, epithelial cells, and dendritic cells. A major function of the lymphatic system is to drain body fluids and return them to the bloodstream. We can survive without our spleen but our immune system becomes greatly weakened and our bodies are then highly susceptible to infections. Chief responsibilities of the lymphatic system are immunity, transportation of interstitial fluid back into the bloodstream, and fat absorption. Peyer’s patches, a type of MALT in the small intestine, are especially important for immune responses against ingested substances. as well as general information on the Introduction To Lymph Page. This inappropriate accumulation of fluid referred to as lymphedema may lead to serious medical consequences. Another type of lymphocyte of importance is the plasma cell. These activated B cells are known as plasma cells. In the embryo, blood cells are made in the yolk sac.
Lymph flows from the lymphatic capillaries, through lymphatic vessels, and then is dumped into the circulatory system via the lymphatic ducts located at the junction of the jugular and subclavian veins in the neck. Lymphatic capillaries, also called the terminal lymphatics, are vessels where interstitial fluid enters the lymphatic system to become lymph fluid. As development proceeds, this function is taken over by the spleen, lymph nodes, and liver. No matter how accurate I am trying to be with the information here I am sure there are going to be errors. Interstitial fluid pertains to the liquid substance between cells, serving as a transport vehicle for nutrients and waste. thelymphguy@gmail.com This is where the lymphatic system comes into play.
When interstitial pressure is low, the endothelial flaps close to prevent “backflow.” As interstitial pressure increases, the spaces between the cells open up, allowing the fluid to enter. Later, the bone marrow takes over most hematopoietic functions, although the final stages of the differentiation of some cells may take place in other organs. These cells can be divided into three classes based on function: Figure 10.4: Hematopoietic System of the Bone Marrow. Histologically, tonsils do not contain a complete capsule, and the epithelial layer invaginates deeply into the interior of the tonsil to form tonsillar crypts. ).
The red pulp consists of reticular fibers with fixed macrophages attached, free macrophages, and all of the other cells typical of the blood, including some lymphocytes. The lymphatic system is a network of delicate tubes throughout the body.
The two basic types of lymphocytes, B cells and T cells, are identical morphologically with a large central nucleus surrounded by a thin layer of cytoplasm.
