LYMPHATIC ENDOTHELIUM Meaning and
Definition
-
Lymphatic endothelium refers to the specialized type of endothelial tissue that lines the walls of lymphatic vessels. Endothelium is the thin layer of cells that forms the innermost lining of blood vessels and lymphatic vessels.
The lymphatic system is a network of vessels, nodes, and organs that is responsible for the transport and filtration of lymph, a fluid that contains white blood cells, waste products, and excess fluid from tissues. The lymphatic vessels collect and carry the lymph throughout the body back to the bloodstream.
The lymphatic endothelium plays a crucial role in maintaining the integrity and functionality of the lymphatic system. It is characterized by unique structural and functional features that enable it to regulate the movement of fluid, molecules, and immune cells into and out of the lymphatic vessels.
The lymphatic endothelial cells are typically flat, with overlapping edges that form tiny gaps known as intercellular junctions. These intercellular junctions are more permeable than those found in blood vessels, allowing for the easy entry of fluid, molecules, and immune cells into the lymphatic vessels.
Furthermore, the lymphatic endothelium is equipped with lymphatic capillaries that possess tiny finger-like structures called lymphatic endothelial cells. These cells can open and close in response to changes in fluid pressure, allowing them to absorb and transport the lymph more efficiently. In addition, they assist in filtering and trapping foreign particles, pathogens, and cancer cells present in the lymphatic fluid.
Overall, the lymphatic endothelium is an essential component of the lymphatic system, contributing to the maintenance of fluid balance, immune surveillance, and transport of important substances that are vital for overall bodily function.

Etymology of LYMPHATIC ENDOTHELIUM
The word "lymphatic" is derived from the Latin word "lymphaticus", which means "pertaining to water". It stems from the Greek word "lymphein", meaning "to make watery". The term "endothelium" is also of Greek origin, with "endo-" meaning "within" and "thelium" meaning "tissue".
The combination of these two words, "lymphatic endothelium", is used to describe the thin layer of cells that line the inside of lymphatic vessels. These cells are responsible for the transport and filtration of lymph fluid throughout the body.
