What are the Differences Between Blood and Lymphatic Capillaries?
The main differences between blood capillaries and lymphatic capillaries include:
- Structure: Blood capillaries have a continuous basement membrane and tight junctions, while lymphatic capillaries have an incomplete basement membrane and overlapping endothelial cells with minivalves. - Function: Blood capillaries are involved in the exchange of gases, nutrients, and waste products between blood and tissues, whereas lymphatic capillaries collect interstitial fluid and play a role in immune surveillance. - Distribution: Blood capillaries are found in almost all tissues, while lymphatic capillaries are absent in certain areas like the central nervous system and avascular tissues.
