by cleansing lymph
B
by checking for invaders and foreign substances
C
by activating and producing lymphocytes
D
all of these
Explanation: 

Detailed explanation-1: -Protects your body against foreign invaders: The lymphatic system is part of the immune system. It produces and releases lymphocytes (white blood cells) and other immune cells that monitor and then destroy the foreign invaders-such as bacteria, viruses, parasites and fungi-that may enter your body.

Detailed explanation-2: -The lymphatic system is important for the optimal functioning of our general and specific immune responses. The lymph nodes monitor the lymph flowing into them and produce cells and antibodies which protect our body from infection and disease.

Detailed explanation-3: -Primary lymphoid organs: These organs include the bone marrow and the thymus. They create special immune system cells called lymphocytes. Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils and certain tissue in various mucous membrane layers in the body (for instance in the bowel).

Detailed explanation-4: -Together, the blood, heart, and blood vessels form the circulatory system. The lymphatic system (lymph, lymph nodes and lymph vessels) supports the circulatory system by draining excess fluids and proteins from tissues back into the bloodstream, thereby preventing tissue swelling.
