Definitions:

Phagocytosis

A cellular process where cells engulf and digest particles or other cells, a crucial part of the immune response.

Activated T Cells

Immune cells that have been stimulated by an antigen to provide an immune response against infections and diseases.

Antibody Formation

The process by which the immune system produces antibodies in response to foreign substances (antigens) to neutralize or eliminate them.

Nonspecific Defenses

Nonspecific defenses refer to the innate immune response mechanisms that provide a general protection against pathogens, without targeting specific ones.
