NEET BIOLOGY

Detailed explanation-1: -White blood cells are the key players in your immune system. They are made in your bone marrow and are part of the lymphatic system. White blood cells move through blood and tissue throughout your body, looking for foreign invaders (microbes) such as bacteria, viruses, parasites and fungi.

Detailed explanation-2: -Proteins help form immunoglobulins, or antibodies, to fight infection ( 25, 26 ). Antibodies are proteins in your blood that help protect your body from harmful invaders like bacteria and viruses. When these foreign invaders enter your cells, your body produces antibodies that tag them for elimination ( 27 ).

Detailed explanation-3: -The major proteins of the immune system are predominantly cytokines (a type of hormone responsible for communication between cells of the immune system), antibodies (immunoglobulins), and complement proteins.

Detailed explanation-4: -3. Glutamine. The amino acid glutamine (L-glutamine) plays a significant central role in maintaining immune function. The effects of glutamine include helping to create and mobilize white blood cells and aiding in phagocytosis.
