White Blood Cell Basics
First Line of Defense
Mystery
The Immune Response
Vaccines
100

The part of the body where most white blood cells are produced.

What is bone marrow?

100

This organ is the body's largest physical barrier against pathogens.

What is the skin?

100

A disease causing organism

Pathogen
100

One of the body's first responses to injury or infection

inflammatory response

100

Vaccines help protect the body against these two types of infectious organisms.

What are bacteria and viruses?

200

The organ that monitors blood for pathogens and removes old blood cells.

What is the spleen?

200

This response increases blood flow to an injured or infected area.

What is inflammation?

200

Infection transmission that involves breathing in infectious particles

Airborne transmission

200

Cells that produce antibodies 

B Cells

200

These cells remain after vaccination and help the body respond faster to future infections.

What are memory cells?

300

The most common type of white blood cell.

What are neutrophils?

300

This type of immunity does not require the body to have encountered the pathogen before.

What is innate immunity?

300

A state where the body's immune system malfunctions and attacks its own healthy cells and tissues instead of harmful foreign invaders like bacteria or viruses

Autoimmune 

300

a marker that tells your immune system whether something in your body is harmful or not.

antigen

300

When enough people are immune, infections have fewer opportunities to spread. This is called ____ immunity 

herd/community

400

Basophils release this chemical involved in allergic reactions

What is histamine?

400

A substance on a pathogen that the immune system recognizes as foreign.

What is an antigen?

400

life-threatening organ dysfunction caused by a dysregulated host response to infection


Sepsis

400

protective proteins produced by your immune system. They attach to antigens (foreign substances) — such as bacteria, fungi, viruses and toxins — and remove them from your body.

antibodies

400

These additional vaccine doses help maintain or strengthen immunity over time.

What are boosters?

500

A Complete Blood Count (CBC) showing an elevated white blood cell count may suggest this.

What is infection or inflammation?

500

This kind of T cell identifies a body cell that has become infected and destroys it.

What is a cytotoxic T cell?

500

Eosinophils help the body fight against which type of infections

Parasitic
500

Small signaling proteins released by immune cells to communicate with one another

cytokines

500

This type of vaccine provides genetic instructions for cells to produce a protein that triggers an immune response.

What is an mRNA vaccine?
