The human lymphatic system

The lymphatic system is the body's defense system, it is closely related to the cardiovascular system. The lymphatic system can be manufactured white blood cells and antibodies, the pathogen was filtered off, and also has an important role in the in vivo distribution for liquid and nutrient.

Like over the body's blood circulatory system, the lymphatic system is a mesh of liquid systems. The flow of lymph in the lymphatic system, turns from plasma, but plasma cleared, more water, penetrated the organization from the capillary wall space.

The spleen is the largest lymphoid organ, the spleen can filter the blood to remove aging red blood cells, usually as a blood bank reserve excess blood.

Many pipeline lymphatic system and lymph nodes, lymphatic capillaries throughout the body, to collect the excess liquid, enter two total catheter: a trunk thoracic duct of the lymphatic system, and the spine parallel to each other, leading to the left near the heart of a large vein; another a right lymphatic duct, leading to the right of the vein.

The lymphatic system is not like the heart as the pump pressure to send the lymph. New tissue fluid flowing into the liquid in the gaps between cells to squeeze into the lymphatic. Artery and muscle constrictor lymph forward pressure is applied. Respiration cause negative pressure within the thoracic duct, the lymph upward flow back into the blood.

One was injured tissue swelling, and rely on the lymphatic system to eliminate the accumulation of liquid restore normal liquid loop.

Along the lymphatic capillaries have over 100 lymph nodes or lymph glands, body and neck, groin and armpits, especially intensive. Each lymph node, there are a series of fiber valve, lymph from the stream, filter out microorganisms and toxins, and to be abolished, in order to prevent the spread of infection.

When the virus invades the human body to infection, lymph node enlargement pain. Touched two lumps under the chin like a sore throat, lymph node that is. Lymph node mass will naturally reduce inflammation disappeared.
