It is also in charge of defending our bodies from diseases. This is because the lymphatic system provides the place for formation and maturation of the lymphocytes which the white blood cells involved in immunity which are activate when they are in contact with antigens.

Role of the parts: Lymph nodes – Lymph nodes are enclosed, located around the lymph vessels.

To contribute to the movement of the lymphatic duct, there are a number of ways to check if valves are found in the lymphatic system. This checks if the valves are accepting lymph to manoeuvre to the lymphatic ducts and when the lymph tries get away from the ducts. In the limbs, the skeletal muscles contract and squeeze the walls of the lymphatic vessels to push the lymph through the valves and near the thorax. Within the trunk the diaphragm pushes into the abdomen during inward breathing. The expanded abdominal pressure pushes the lymph into the less tensioned thorax. The pressure gradient turns around amid exhalation, yet the check valves stop the lymph from being pushed
