Lymphatic system. Their illnesses

Since blood is never in direct contact with the cells that form tissues of different organs and that does not leave the closed system of blood capillaries, the question arises: How will nourish the cells of our body?

The nutritional content of our blood is responsible for having to nourish our cells with oxygen, vitamins, minerals, etc.. In order to achieve what is filtered through the thin wall of blood capillaries is a clear fluid, rich in early nutritive tissue called lymph. This interstitial fluid is that which enables the nutrition and elimination of tissue residues.
Composition of lymph

Lymph has a composition similar to blood plasma, but with less amount of protein. It also contains numerous lymphocytes from lymph nodes or lymph nodes that are located in specific regions of the body throughout the system. Its composition is: 93-96% water, 4-7% dissolved solids, among which are proteins (3-4%), fat (0.5-1%) and minerals (0,4-0 , 8%).

Lymphatic circulation
The lymphatic fluid then presents in some fine tubes called lymphatic vessels (very similar in structure to the blood vessels), which bind together to form larger caliber trunks, collecting and downloading the lymph in the blood through the thoracic and right lymphatic ducts.

The lymph circulation due to the difference between tissue pressure and venous pressure, the massage exerted by the muscles to contract and, perhaps, to the contractile activity of lymphatic vessels themselves.

Lymphoid organs

The lymphatic system consists of a number of bodies and a tubular system (lymphatic vessels), each with different functions and structures. Lymphoid organs are:

* Timo. Primary organ in which occurs the differentiation of undifferentiated cells that left the bone marrow, thus turning them into mature T cells.
* Spleen. Central immune organ in the blood circulatory system.
* Tonsils. Waldeyer's lymphatic ring. They are immune to the throat and mouth cavidas.
* Red marrow. Formation of blood and immune cells.
* Pleyer plates. Immune defenses in the large intestine and appendix.
* Lymph nodes. Nursing stations and control the immune system.

Lymph nodes
Along the lymphatic circulation are the lymph nodes are like seasons of rest and treatment in the lymph circulation. The lymph nodes are very important for organic defense in case of infection. For example, in the case of a foot infection caused by a wound, which pathogens can reach the nodes in the groin for producing a thickening of these nodes. Nodes may swell and start to hurt (lymphadenitis).

Lymph nodes produce immune cells that help the body fight infections. In addition to filtering the lymph fluid and remove foreign material such as bacteria and cancer cells, lymphatic fluid recognizes when bacteria produce more white blood cells to fight infection, making them inflamed.

Diseases of lymph or lymphatic system
Some of the lymphatic system diseases highlight the following:

* Lymphatism. State constitutional frequent in children characterized by an overgrowth (hypertrophy) of lymph tissue causing a state of lowered resistance to infection. In this case the tonsils are enlarged and the lymph nodes in neck, armpit, etc. In this condition the person is more prone to bronchial catarrh, asthma, adenoids, tuberculosis infection.
* Lymphadenitis. It is acute or chronic inflammation of one or more lymph nodes caused by a previous infection. Because of a wound infection, abscess, etc.., Bacteria are transported by the lymphatic or blood stream and reach regional lymph nodes where they cause inflammation of these glands. Among the chronic lymphadenitis is the scrofulous.
* Lymphadenoma Linfoadenoma or Hodgkin's Disease. It is a primary neoplasm of lymphoid tissue that is characterized by the finding of Reed-Sternberg cells in lymph and tissues. There are four histologic variants of the disease: lymphocytic predominance, nodular sclerosis, mixed cellularity and lymphocyte depletion.
* Lymphangitis. It is acute or chronic inflammation of the lymph vessels, caused by bacteria that have entered the lymphatic circulation through wounds or a septic focus (abscess, boil, etc.).. Acute lymphangitis causes pain along the vessel inflamed and sometimes fever.
* Lymphangioma. Angioma-like tumor blood but with the peculiarity that instead of blood containing lymph, because it consists of the formation of new lymphatic vessels and not blood. Distinguish between simple lymphangiomas, cavernous and cystic. They may be congenital or acquired and occur mainly in cheeks, lips, neck and tongue.
* Linfangectasia or Elephantiasis. It is the dilatation of the duct or lymphatic vessel causing a stagnation of lymph, which circulates inside. The stagnation of lymph causes thickening more or less noticeable, mammoth type, skin and subcutaneous tissue, which is called elephantiasis.
