Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.
        Help!  

Question
Answer
Define Immunity   A reaction that occurs in animals and humans in response to an infection  
🗑
Define the Immune System   It assists the body to resist infection and disease through specialized cells  
🗑
What is it meant by "self" and "Non self"   ‘self’ – material made by the body it inhabits ‘non-self’- materials, including cells that are not made by the body it inhabits.  
🗑
Antigens   Are compounds usually made of protein and carbohydrates, they can be ‘self’ or ‘non-self’. Can trigger the immune system to respond. Usually located on the surface.  
🗑
AntiBodies   Are proteins produced by lymphocytes in response to non-self Antigens. They react specifically with the Antigens that trigger their production.  
🗑
Pathogens   Are organisms that are able to cause a disease in a host. Antigens on the surface of the Pathogen will trigger the immune system to respond.The Antibody will react with the Antigen by combining with it and disabling it  
🗑
Nonspecific Immunity   Same reaction to all infections, No ‘memory’ of prior infections. Same response level for each infection of the same organism.  
🗑
Specific Immunity   Specific reactions to each infection, ‘Memory’ of prior infections, Much greater response level on a second infection on the same organism.  
🗑
What is the general purpose of the first line of defence?   To stop the infection or micro- organism by attempting to stop them from entering the body.  
🗑
First Line of Defence   Skin, Mucous membranes, Natural secretions, Natural flora.  
🗑

To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
