White Blood Cell Basics
The part of the body where most white blood cells are produced.
What is bone marrow?
This organ is the body's largest physical barrier against pathogens.
What is the skin?
A disease causing organism
One of the body's first responses to injury or infection
inflammatory response
Vaccines help protect the body against these two types of infectious organisms.
What are bacteria and viruses?
The organ that monitors blood for pathogens and removes old blood cells.
What is the spleen?
This response increases blood flow to an injured or infected area.
What is inflammation?
Infection transmission that involves breathing in infectious particles
Airborne transmission
Cells that produce antibodies
B Cells
These cells remain after vaccination and help the body respond faster to future infections.
What are memory cells?
The most common type of white blood cell.
What are neutrophils?
This type of immunity does not require the body to have encountered the pathogen before.
What is innate immunity?
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
a marker that tells your immune system whether something in your body is harmful or not.
antigen
When enough people are immune, infections have fewer opportunities to spread. This is called ____ immunity
herd/community
Basophils release this chemical involved in allergic reactions
What is histamine?
A substance on a pathogen that the immune system recognizes as foreign.
What is an antigen?
life-threatening organ dysfunction caused by a dysregulated host response to infection
Sepsis
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
These additional vaccine doses help maintain or strengthen immunity over time.
What are boosters?
A Complete Blood Count (CBC) showing an elevated white blood cell count may suggest this.
What is infection or inflammation?
This kind of T cell identifies a body cell that has become infected and destroys it.
What is a cytotoxic T cell?
Eosinophils help the body fight against which type of infections
Small signaling proteins released by immune cells to communicate with one another
cytokines
This type of vaccine provides genetic instructions for cells to produce a protein that triggers an immune response.
What is an mRNA vaccine?
