What “happens” in the lymph nodes?
A
Excess glucose in the lymph is stored in the liver
B
Carbon dioxide is removed from the lymph and passed to the lungs for exhalation
C
Lymph is oxgenated and pumped through the body
D
Lymph is cleaned of foreign antigens and debris
Explanation: 

Detailed explanation-1: -The lymph nodes also filter the lymph fluid. Macrophages in the sinus spaces phagocytize (engulf) foreign particles such as pathogen, so that lymph fluid that returns to the bloodstream is cleaned of problematic abnormalities.

Detailed explanation-2: -Those germs are filtered out in the lymph nodes, small clumps of tissue along the network of lymph vessels. Inside the lymph nodes, lymphocytes called T-cells and B-cells help the body fight infection.

Detailed explanation-3: -As a filter for the fluid that flows through your cells and tissues, lymph nodes clean up and get rid of lymphatic fluid waste and invaders that cause illness, while holding onto the components of your lymphatic fluid that keep you healthy.

Detailed explanation-4: -Antigens and dendritic cells (DCs) reach the draining lymph node through afferent lymphatic vessels; they must then enter the lymph node and migrate deep into it to activate T cells. Lymph nodes are enclosed in a collagen-rich capsule, which is underlined with lymphatic endothelial cells forming the subcapsular sinus.

Detailed explanation-5: -All of the fluids and its contents that leak out into the tissues (as well as waste products formed in the tissues, and bacteria that enter them through our skin) are removed from them by the lymphatic system.
