ANATOMY

Detailed explanation-1: -Antibodies are protective proteins produced by your immune system. They attach to antigens (foreign substances)-such as bacteria, fungi, viruses and toxins-and remove them from your body.

Detailed explanation-2: -Animal-based foods (meat, poultry, fish, eggs, and dairy foods) tend to be good sources of complete protein, while plant-based foods (fruits, vegetables, grains, nuts, and seeds) often lack one or more essential amino acid.

Detailed explanation-3: -antibody, also called immunoglobulin, a protective protein produced by the immune system in response to the presence of a foreign substance, called an antigen. Antibodies recognize and latch onto antigens in order to remove them from the body.

Detailed explanation-4: -An antigen is any kind of marker-like a protein or string of amino acids-that your immune system can recognize. If this definition seems a little vague to you, you’re not alone. Let’s dig in further. Antigens are usually proteins or sugars (polysaccharides) found on the outside of things like cells or viruses.

Detailed explanation-5: -Immunoglobulins (Ig) are antibodies and there are five major classes of antibodies: Immunoglobulin A (IgA), immunoglobulin G (IgG), immunoglobulin D (IgD), immunoglobulin M (IgM), and immunoglobulin E (IgE).
