What role do antibodies play in immunity? How are they produce d and how do they work?
The general structure of lymphatic vessels is similar to that of blood vessels since these are the only two types of vessels in the body.
While blood and lymph fluid are two separate substances, both are compos ed of the same water (plasma or fluid) found elsewhere in the body.
Layers of Lymph Vessels
The endothelium, a general term for the inner layer of a vessel, is compose d of an inner lining of single, flattened epithelial cells (simple squamous epithelium).
This layer mechanically transports fluid. It sits on a highly permeable basement membrane made out of extracellular matrix that separates the endothelium from the other layers.
The endothelium is designed with junctions between cells that allow interstitial fluid to flow into the lumen when pressure becomes high enough (such as from blood capillary hydrostatic pressure), but does not normally allow lymph fluid to leak back out into the interstitial space.
