Lymphatic capillaries collect the tissue fluid or lymph from the intercellular spaces in tissues. These capillaries join to form larger lymph vessels, which eventually empty into larger veins.

Lymphatic capillaries collect the tissue fluid or lymph from the intercellular spaces in tissues. These capillaries join to form larger lymph vessels, which eventually empty into larger veins.
Lymphatic capillaries play a crucial role in the lymphatic system by collecting and transporting lymph, a fluid derived from interstitial fluid. These capillaries have specialized endothelial cells with overlapping edges, forming one-way valves that permit the entry of interstitial fluid, dissolved substances, and immune cells into the lymphatic system. Unlike blood capillaries, lymphatic capillaries lack a continuous basement membrane, allowing for increased permeability. As lymphatic capillaries converge into larger vessels, they help maintain fluid balance, transport immune cells, and facilitate the return of lymph to the bloodstream, contributing to immune function and overall homeostasis in the body.
