Detailed explanation-1: -Lymph capillaries help keep the overall fluid balance in your body. Throughout your body, interstitial fluid (fluid found in the spaces around cells) leaks from blood capillaries into your tissues. Lymph capillaries pick up this fluid and help return it to your circulatory system.
Detailed explanation-2: -As soon as the interstitial fluid enters the lymph capillaries, it is called lymph.
Detailed explanation-3: -They extend out from the lymphatic capillary, attaching lymphatic endothelial cells to surrounding tissues. When excess interstitial fluid accumulates and causes tissue swelling, the anchoring filaments are pulled, making the openings between cells even larger so that more fluid can flow into the lymphatic capillary.
Detailed explanation-4: -Interstitial fluid, formed from the extravasation of solute and fluid from the capillaries, enters blind-ended sacs composed only of an endothelial layer that is tethered to the interstitial matrix. These bulbous sacs (10–60 m diameter) are called initial, or terminal, lymphatics.
