The body's first line of defense against pathogens, using non-specific methods to fight off infection.

External defenses like skin, mucus membranes, and fluids that prevent pathogens from entering the body.

White blood cells that engulf and destroy pathogens.

A process that recruits white blood cells to the site of infection and helps prevent spread of infection

A group of proteins in the blood that help destroy pathogens by damaging pathogen membranes.

A specific immune response that develops over time, targeting particular invaders.

A response to an infection without prior exposure to the specific pathogen.

Immune response that specifically targets the pathogen after exposure to the pathogen.

The immune system's continuous monitoring of the body for signs of damage or disease.

Specialized immune cells involved in the adaptive immune response.

Immune cells communicating with each other using various chemical signals.

The immune system's targeted attack on the identified threat.

The immune system is made up of cells, tissues/organs, and effector molecules that work together to fight infections and diseases.

A substance that triggers an immune response. It can be from microbes, or from other sources.

Low-molecular weight proteins that are secreted by cells and regulate immune response by coordinating communication between immune cells.

Cytokines that attract immune cells to areas of infection or inflammation.

Surface proteins on cells that help identify cell type. Different cells have unique mixtures of CD molecules.

Molecules that carry out the actions of the immune response (e.g., complement proteins, antibodies).

A type of lymphocyte that plays a critical role in cell-mediated immunity.

Proteins on a cell's surface used to identify the cell type

A group of proteins in the blood that fight infection.

Proteins that help immune cells eat bacteria.

Immune response where white blood cells enter tissues.

Destruction of cells by the immune system.
