===Removal of interstitial fluid===

Due to their structure lymphatic capillaries are more permeable than vascular capillaries and this means that they can not only more effectively remove fluid from tissue but also take up large molecules. This allows the lymphatic system to transport large proteins as well as chylomicrons for the transport of fats. The interstitial fluid filtered into the lymphatic vessels is called lymph. As the vessels pass through lymph nodes the lymph is surveyed by immune cells before returning to the blood ensuring that antigens/pathogens from tissues are removed.

Due to their structure lymphatic capillaries are more permeable than vascular capillaries and this means that they can not only more effectively remove fluid from tissue but also take up large molecules. This allows the lymphatic system to transport large proteins as well as chylomicrons for the transport of fats. Chylomicrons enter the lymph to eventually join the blood via the thoracic duct; this enables the lipid soluble [[Small Intestine - Anatomy & Physiology#Triacylglycerol Digestion and Absorption |triacylglycerol (TAG)]] to be transported into the blood.

 

The interstitial fluid or lymph filtered into the lymphatic vessels passes through lymph nodes and is surveyed by immune cells before returning to the blood ensuring that antigens/pathogens from tissues are removed.

Chylomicrons are too large to enter the capillaries but instead enter the lymph to eventually join the blood via the thoracic duct.

This enables the lipid soluble [[Small Intestine - Anatomy & Physiology#Triacylglycerol Digestion and Absorption |triacylglycerol (TAG)]] to be transported into the blood.
