==Introduction==
The lymphatic system can be divided into two anatomical and functional subsets: [[Lymphatic Vessels - Anatomy & Physiology|lymphatic vessels]] that carry [[Lymph - Anatomy & Physiology|lymph]] around the body, and the [[Lymphoreticular System - Anatomy & Physiology|lymphoreticular system]] which describes the lymphoid tissues. The lymphatic system has three functions - immune defence, removal of interstitial fluid from tissues and the transport of fats.

The lymphatic system has three functions - immune defence, removal of interstitial fluid from tissues and the transport of fats.
==Lymphatic Vessels and Lymph==
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 - Anatomy & Physiology|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.
==Lymphoreticular system==
==Lymphoreticular system==
The lymphoreticular system produces [[Immunology|immune cells]] and removes senescent cells.
