Innate Immune System (Parts 1+2)
What is the correct physiology of mucus?
Trap bacteria and harmful substances
What is the best example of a self antigen?
a. Antigens on your heart cells
b. Antigens on the flu virus
c. Antigens on a parasite cell
d. Antigens on a bacteria cell for the common cold
A) Antigens on your heart cells
What does the word lymphocyte mean?
White blood cell
What is the definition of innate immunity
Immunity that you are born with
What is the best example of a “nonself antigen”
a. Antigens that are on your brain cells
b. Antigens that are on your lung cells
c. Antigens that are on the COVID virus
d. Antigens that are on your eye cells
C) Antigens that are on the COVID virus
What is the definition of a pathogen and give an example
Another word for bacteria, virus or anything that makes you sick (Ex: flu, covid, HIV, etc)
Describe the anatomy and physiology of natural killer cells
Made up of large granules and they are responsible for fighting off cancer cells
Describe how T-cells and B-cells work
T cells = make copies of themselves to fight the pathogen
B= creates antibodies
Describe what the word antigen means and use it in a sentence to explain how the immune system work
An antigen is a protein on the outside of a pathogen
(Antibodies recognize antigens in the body)
Describe the anatomy and physiology of eosinophils
They have a spherical shape and help get rid of parasites
Describe how vaccines work
What is the definition of an antibody and how does it work
It's a protein that deactivates a pathogen. It surrounds the pathogen in order to deactivate it
Describe what happens during the inflammation process (steps)
First, both histamine and kinins are released into the blood. The release of these chemicals causes blood vessels to dilate (expand and become wider). When blood vessels dilate, it allows more blood to flow through. This extra blood is what makes an injury area red. The blood vessels also become leaky (form gaps/holes). The neutrophils (white blood cells) and plasma are released from the blood vessels to the sight of injury. Those neutrophils will engulf (eat) any bacteria that is at the site of injury.
How does an mRNA vaccine work
The cells receive DNA information and create spike proteins (antigens), the b-cells recognize it and create antibodies to help protect against future infection
This word means to learn something (especially relating to immunity)
Acquired
