Passive immunotherapy relies on what to help combat diseases?

1. Components created outside the body

2. Natural immune responses from the patient

3. Local chemotherapy agents

4. Radiation therapy

The correct answer is: Components created outside the body

Passive immunotherapy utilizes components created outside the body, such as antibodies, to help combat diseases, particularly infections and cancer. This approach involves administering pre-formed antibodies from an external source, which can provide immediate immune response without requiring the body to produce its own immune products. For example, polyclonal or monoclonal antibodies can be introduced into a patient to target specific antigens found on cancer cells or pathogens, thereby enhancing the immune system's ability to recognize and eliminate these threats more efficiently. This contrasts with active immunotherapy, where the patient’s own immune system is stimulated to produce an immune response against specific antigens. By leveraging antibodies developed in the lab or derived from donors, passive immunotherapy delivers a rapid and specific response to a disease.
