Question

Quizplus · Accepted Answer

Innate immunity is genetically determined and present at birth. It includes physical barriers (such as skin), chemical defenses (such as enzymes and acids), and immune cells (such as macrophages and natural killer cells). Active immunity is acquired through exposure to an antigen (such as a vaccine) and involves the production of antibodies by the individual's own immune system. Maternal immunity is acquired passively from the mother, either through the placenta during pregnancy or through breast milk. Autoimmunity is a condition when the immune system mistakenly attacks the body's own cells and tissues.
