ANATOMY

Detailed explanation-1: -Active Immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Active immunity can be acquired through natural immunity or vaccine-induced immunity.

Detailed explanation-2: -When the immune system erroneously reacts to the protein components of our body’s own tissues and cells, it produces autoantibodies. Autoantibodies that persist contribute to autoimmune disease development. Specific autoantibodies occur in specific autoimmune diseases.

Detailed explanation-3: -Vaccine Education Center Two types of immunity exist-active and passive: Active immunity occurs when our own immune system is responsible for protecting us from a pathogen. Passive immunity occurs when we are protected from a pathogen by immunity gained from someone else.

Detailed explanation-4: -Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.

Detailed explanation-5: -(PA-siv ih-MYOO-nih-tee) A type of immunity that occurs when a person is given antibodies rather than making them through his or her own immune system. For example, passive immunity occurs when a baby receives a mother’s antibodies through the placenta or breast milk.
