The human body comprises two parallel vital systems: circulatory and lymphatic.The first serves as a power of the body, while the other cleans it from pollutants.Scientists say that the human lymphatic system (LAN) originated during the evolution of the circulatory system.It consists of lymph capillaries, vessels and organs such as the thymus, spleen, limfauzly and performs the function of ensuring the outflow of fluids from the tissues and cells of the body into the circulatory system.However, unlike the circulatory system, drugs has no arteries and does not imply the existence of a vicious circle, so the answer to the question: closed or open lymphatic system, is obvious.
capillaries are connected to each other, thus forming a closed network, which covers almost all organs.They consist of endotolialnyh cells without membrane.Lymphatic capillaries suck destroy cells, including tumor.
capillaries to two millimeters in diameter, fused together to form the lymphatic vessels, which consist of valves, ducts and trunks.Most often, the vessels are located close to the veins;they can bear both the lymph from the skin (epifastsialnye) and lymph borne by the muscles and joints (subfascial vessels).Lymph vessels represents a transparent liquid composition similar to plasma.Lymphatic vessels consists of six channels, which in turn form the two main trunk: thoracic and right lymphatic trunk.
also human lymphatic system carries lymph from within the internal organs.Along the way, is more than ten limfauzlov, which are called "regional".Lymph nodes are the biological filter of the human body: they produce cells that protect the body against various infections and microbes, thereby generating immunity.In the human body there are about one hundred and fifty groups of lymph nodes, the largest of which are located in the neck, in the armpits, in the knee and the elbow, back of the head and in the groin.
biggest limfauzlom assumed spleen.The body that regulates the work of the entire lymphatic system is the thymus, located in the chest.Thus, red blood cells, which fall in the body are converted into lymphocytes capable of eliminating negative formation in humans.In adulthood, these cells turn into fat.
should be noted that the lymphatic system is not closed: the lymph moving in one direction - from the tissues of the body to the heart.In violation of its movement, a person may experience swelling.Lymph supplying cells with oxygen and various nutrients.
important to know that in normal lymph nodes are not palpable.If you have an infection or a tumor, they can be increased, so it is recommended in such cases, seek advice from a specialist.
Talk about how the human lymphatic system, it is possible, after various diagnostic procedures such as palpation, ultrasound tests and imaging.Today there is a large number of different diseases of the lymphatic system, so early diagnosis can help in time to make a diagnosis and start appropriate treatment.
Thus, the lymphatic system of the person, along with the circulatory system plays an important role in the functioning of the human organism.As a protective barrier against many infections and diseases, it helps to enter the human organs of oxygen and nutrients, and the removal from it of the decay products, and even cancer cells.
