The immune system is the bodys defense against infectious organisms and other invaders. Immune response is the process by which the immune system attacks and defends against organisms and substances that attack the bodys systems and cause disease.
Among the network of cells, tissues, and organs that work together to protect the body are white blood cells, or leukocytes, which function to seek out and destroy disease-causing organisms or substances.

These leukocytes are also known as lymphoid organs because of where they are stored throughout the body. Leukocytes are also present in the bodys lymph nodes and circulate through the bodys organs and nodes via lymphatic vessels and blood vessels.
The immune system orchestrates a coordinated monitor-and-response process, identifying germs or other irregular substances in the body that might impair cell or system function. Unfortunately we know that the immune system is not responsive to drugs for healing; for example long-term use of antibiotics to fight infections can actually depress the immune system.
