Anatomy 12.3 - Specific Defenses

The cells and chemicals that contribute to the body's specific defenses against diseases

• humoral immunity

• immune system

• immunoglobulins

• cellular immunity

Cells that process protein antigens and present them on their surface in a form that can be recognized by lymphocytes, are also necessary for proper immune function.

• cellular immunity

• major histocompatability complex glycoproteins (MHC's)

• antigen presenting cells (APC)

• memory cells

A programmed process of cellular self destruction (suicide) ensuring it does not attack the body’s own tissues.

• precipitation

• passive immunity

• primary immune response

• apoptosis

When a lymphocyte divides repeatedly, making many copies of itself. Each copy is an exact genetic clone of itself

• clonal selection

• active immunity

• precipitation

• memory cells

A few lymphocyte clones become these cells that reside in the lymphatic tissues ready to respond in case the antigen re-invades the body.

• passive cells

• memory cells

• apoptosis

• mast cells

A family of proteins on the surface of the lymphocyte that help the immune system recognize a foreign antigen.

• cellular immunity

• major histocompatibility complex glycoproteins (MHC's)

• primary immune response

• secondary immune response

Also called antibody mediated immunity. It is immunity that is associated with free antibodies that circulate in the blood.

• passive immunity

• immune system

• cellular immunity

• humoral immunity

Proteins that recognize particular antigens with great specificity. Also known as antibodies

• memory cells

• immunoglobulins

• apoptosis

• active immunity

The formation of an insoluble complex, such as a clump of antigen molecules joined together by antibodies.

• passive immunity

• precipitation

• cellular immunity

• apoptosis

The initial response when an antigen or invader initially enters the body. Detection of its presence may take awhile.

• cellular immunity

• secondary immune response

• primary immune response

• humoral immunity
