The lymphatic vessels form a tubular structure and serve to transport aqueous solutions. In the body, they pass by the veins and arteries.
What are lymph vessels?
Lymph vessels are similar to The Shape of blood vessels. However, they are not responsible for the transport of blood, but for the transport of Lymphe. Lymphe is a light yellow liquid.
It has protein, fat and water. It also contains important immune cells that are essential for the defense of the body. Lymphoma is found throughout body tissue, so lymph vessels also appear in all tissues.
One exception is bones, cartilage and teeth. Lymph nodes also play an important role in relation to the lymph vessels. Lymph nodes are an important component of the defense system. They act as filtration stations and have the task of purifying Lymphe.
With the lymph vessels, the lymph nodes form the lymphatic system of the human body. The vessels begin with a small Astrology system and are joined in large lines. They are parallel to the venous vessels and extend throughout the body.
Anatomy And Construction
Four vascular types are distinguished in the lymphatic vessels. Each of them is accompanied by different manifestations and tasks. However, vascular types share some similarities. So all the lymph vessels are made of three layers of Wall. Intimacy is the most intimate. The media and Adventitia join in that.
The lymphatic capillaries form the finest form of the four vascular types. With them, the lymphatic system can reach the deepest tissues. In the form of an AST system, lymphatic capillaries are able to absorb even small amounts of tissue fluid. Capillaries have a width of 50 µm as the minimum unit of the lymphatic system.
Pre-plates form the next level. They collect the tissue fluid and transmit it to the third vascular form to the so-called collectors.
Collectors contract at regular intervals to compress lymphoma to the nearest collectors.
After all, lymphatic strains are the largest vascular form of the lymphatic system. They collect the lymphoma from the collectors and flow into the venous bloodstream. Unlike blood vessels, lymph vessels do not form a closed system.
Function And Tasks
First, the lymph vessels are responsible for the transport of the remaining lymphoma. This is tissue fluid that has not been completely absorbed by the blood vessel system. To this must be added the protein molecules. They are returned to the venous bloodstream along with tissue fluid.
In addition, the immunobiological effect is one of the most important tasks of the lymph vessels. Protects the body from infections and foreign antigens. In addition, defenses that support the immune system are produced. Another function of the lymph vessels is to carry fat. In the framework of the digestion of fat, these are ingested with the diet. In the small intestine, packaged in what is known as chylomicrons. Through the lymph vessels, they enter the blood.
In addition, thanks to lymphatic vessels, metabolites, foreign bodies and pathogens, the body can get rid of them. This also applies to lymph nodes. You perform a purifying function and help the immune system defend itself. In addition, lymphatic vessels have the task of ensuring reliable transport of proteins. In particular, it is intended to prevent the massive accumulation of protein molecules in the interstice.
Interstitial tissue is called interstitial tissue, as it presents itself as binding, supporting, and muscle tissue. If pressure increases as a result of an accumulation of protein molecules, disorders in blood flow may occur. Finally, lymph vessels transport chylomicrons from the gastrointestinal tract. Chylomicrons are small particles that contain cholesterol.
