Detailed explanation-1: -The lymph nodes monitor the lymph flowing into them and produce cells and antibodies which protect our body from infection and disease.

Detailed explanation-2: -The liver produces a large amount of lymph, which is estimated to be 25 to 50% of the lymph flowing through the thoracic duct. 10 Similar to those in other organs, lymphatic vessels in the liver function to retain fluid and regulate the immune system.

Detailed explanation-3: -Effector B cells secrete antibodies, which can act over long distances to help eliminate extracellular pathogens and their toxins. Effector T cells, by contrast, act locally at sites of infection to either kill infected host cells or help other cells to eliminate pathogens.

Detailed explanation-4: -Lymph in the liver originates from plasma components of blood flow filtered through fenestrae of liver sinusoidal endothelial cells. These plasma components (fluids and proteins) enter into the space of Disse, the hepatic version of the interstitial space, and form lymph.
