Lymph capillaries end blindly in the body tissues, where pressure from the accumulation of _ forces the fluid into the lymph capillaries:

Explanation

Lymph capillaries or lymphatic capillaries are tiny, thin walled vessels located in the spaces between cells (except in the central nervous system and non-vascular tissues) which serve to drain and process extracellular fluid. Upon entering the lumen of a lymphatic capillary, the collected fluid along with associated cells (notably white blood cells) is known as lymph. Lymphatic capillaries are slightly larger in diameter then blood capillaries and have closed ends. Their unique structure permits, interstitial fluid to flow into them but not out.
