MICROANATOMY

Detailed explanation-1: -Lymphatic capillaries are similar to blood capillaries, but they are larger in diameter and have closed ends. Unlike blood capillaries, fluid can flow into lymph capillaries but can’t flow out through the cell walls. It can only move forward.

Detailed explanation-2: -Lymphatic capillaries are much more permeable than blood capillaries. Proteins in the interstitial space that can’t enter the blood capillaries can enter the lymphatic capillaries with ease.

Detailed explanation-3: -Lymphatic capillaries are slightly larger in diameter than blood capillaries and contain flap-like “minivalves” that permit interstitial fluid to flow into them but not out, under normal conditions. Lymphatic capillaries are primarily made out of an endothelium layer that sits on a permeable basement membrane.

Detailed explanation-4: -Lymphatic capillaries have a larger diameter the blood capillaries. Lymphatic capillaries have attached anchoring filaments which help to enlarge openings so the fluid can flow in faster.
