Specific and Non-Specific Defense Mechanism Against Infectious ...

ADVERTISEMENTS: Specific and Non-Specific Defense Mechanism Against Infectious Organisms within the Host ! After entering into the host tissues the infectious organisms multiply and may cause diseases. ADVERTISEMENTS: There are some host defense mechanisms, which act against all the intruders immediately after their entry into the host; these defense mechanisms are non-specific in nature (i.e

Specific Defense Mechanism in Human Body | Immunology | Biology

ADVERTISEMENTS: Specific defense mechanism is the ability of the body to develop immunity against specific pathogens, toxins or foreign things. This is possible by a special immune system that produces antibodies and/or activated lymphocytes that attack and destroy specific invading organisms or toxins. Specific defense mechanisms are also referred to as adaptive or acquired immunity […]

Specific immune defence | definition of specific immune defence by ...

specific immune defence: An immune response based on the recognition of a particular antigen. The immune system also provides general, non-specific defence.

What are the nonspecific defense mechanisms that help eliminate foreign invaders?

Lymphocytes and antibodies destroy or immobilize the foreign substance. Nonspecific defense mechanisms (phagocytes, NK cells) help eliminate the invader. Memorization. Long‐lived “memory” lymphocytes are produced and can quickly recognize and respond to future exposures to the antigen or foreign cell.

What is the third line of defense?

The immune system is the third line of defense. It consists of mechanisms and agents that target specific antigens (Ags). An antigen is any molecule, usually a protein or polysaccharide, that can be identified as foreign (nonself) or self (such as MHC antigens described below).

What happens when the immune system recognizes a foreign antigen?

Once the foreign antigen is recognized, an agent is released that targets that specific antigen. In the process of mounting a successful defense, the immune system accomplishes five tasks: Recognition. The antigen or cell is recognized as nonself.
