The adaptive defense consists of antibodies and lymphocytes, often called the humoral response and the cell mediated response.

The acquired response is called adaptive because it prepares the body's immune system for future challenges (though it can actually also be maladaptive when it results in autoimmunity).ometimes the adaptive system is unable to distinguish foreign molecules, the effects of this may be hayfever, asthma or any other allergies. Antigens are any substances that elicit the adaptive immune response.
