GENERAL HISTOLOGY

Detailed explanation-1: -Lymphatic capillaries consist of: Endothelial cells, which line the capillary walls.

Detailed explanation-2: -The lymphatic network is lined by specialized endothelial cells known as LECs.

Detailed explanation-3: -The wall of the lymph capillary is composed of endothelium in which the simple squamous cells overlap to form a simple one-way valve. This arrangement permits fluid to enter the capillary but prevents lymph from leaving the vessel. The microscopic lymph capillaries merge to form lymphatic vessels.

Detailed explanation-4: -Endothelial cells form a single cell layer that lines all blood vessels and regulates exchanges between the bloodstream and the surrounding tissues.
