O lymphatic system it is an accessory system of the cardiovascular system, it is formed by Organs lymphatic organs, lymphatic vessels, lymph nodes and lymph, there are great functions in our body. Are we going to meet any of them?

The lymphatic system is a liquid flow system as already mentioned, the lymphatic system in its structure presents sets of great importance for its functioning, such as: Lymphatic vessels, lymph, some major organs such as the spleen, thymus, palatine tonsils, lymph nodes, this set plays the role of reaching every bit of the body for the filtering.
In the functional scope it produces defense cells for the organism, destroys microorganisms and foreign particles, and in the digestive system it has the function of transporting fat droplets, but the main function is to remove the liquid accumulated in the interstitial space and return it to the system cardiovascular, acts on the immune system, as it protects immune cells, absorbs fatty acids and fluid balance in tissues, it is very function, isn't it?
Let's get to know a little more about the systems that make up the lymphatic system?
Lymph nodes or lymph nodes: They are small organs, measuring up to 2 cm or less, it is formed by lymphoid tissues and there is the presence of different lymphatic vessels, they are present throughout part of the human body, its shape can be compared to a grain of beans, its function is to filter the lymph, from this filtration it removes some particles that do not serve the body, forming a barrier that prevents the entry of these particles into the circulatory system, that is, it is an element of the Imune system.
Lymph nodes can also show that something is wrong with our body, such as an increase in lymph nodes forming small lumps in areas such as the neck, groin, armpits, chest, abdomen, that's it. it occurs because some disease or infection is affecting some area of the body, reaching the immune system, this occurs because the lymph nodes are filtering the lymph and removing foreign beings from the same.
Lymph: Lymph is formed by water, proteins, it is usually colorless, that is, it is light in color, it needs the lymphatic vessels to move freely slowly in our body, that is, it is a liquid present in these vessels, from there that it is considered the lymph. In the intestine region, this lymph presents fat droplets with a more yellowish color. Lymph is produced by the intestine and the liver, its transport is carried out by the lymphatic vessels, this transport is unidirectional, it follows a single direction, let's see how it is performed in vessels in 3 phases:
Lymphatic or initial lymphatic capillary: This vessel is centralized in the skin region, more superficially, it has some pores through which the intestinal fluid, as mentioned, passes into the vessel, it passes through the pressure that the liquid exerts on the vessel and also the pressures caused by the contraction of the muscles and by the pulsation of the arteries, when the liquid passes through the lymphatic capillary, the vessels unite, forming the pre-collector or post-collector vessels. capillaries.
Pre-collector vessels: They are large vessels, in their structure there is connective tissue, elastic tissue and finally muscle tissue, the lymph follows the directional direction, these valves prevent the reflux of lymph. The pre-collector vessels unite, with this union ducts are created, these ducts have large shapes.
Lymphatic Ducts or Collectors: They present all the tissues of the pre-collecting vessels, in addition to these there are: tunica intima media and adventitia, we find in these ducts the lymphangion, which is a unit function of the lymphatic system, characteristics such as rhythm and speed in the lymph drainage process, with only two ducts in the body: thoracic duct and duct lymphatic
The thoracic is a duct in the central region of the abdomen, its function is to drain the intestinal lymph in the left lower limbs, left hemitrunk and in the head region, the lymphatic duct drains the lymph in the right lower limb, right hemithorax and the head.
Spleen: Unlike lymph nodes, it is one of the largest organs of the lymphatic system, it is found behind the stomach, below the diaphragm, its shape is oval and it can weigh 150 grams, its function is to defend the organism (immunological and hematological), eliminate red blood cells that have no function, it is an organ of structure fragile.
Thymus: The thymus is a very small organ, but with great functions, it has a role in the formation of the immune system and protect when an invader tries affect our health is located between the lungs, very close to the heart, even with its small size over the years it can still decrease more. A curious thing about the thymus is that many anatomists believe that the soul is located in the thymus.
Patina Tonsils: There are two organs located in the throat at the back of the mouth, tonsils or palatine tonsils, they have a rounded shape, they consist of lymphoid tissue, are part of the respiratory process and have important functions in the immune system and lymphatic, helps the body fight viruses and bacteria because it is located in the central region of the mouth or even by the nose.
Diseases related to the lymphatic system can be lymphedema, cellulitis, elephantiasis.
