Immune system

Question 1

Humoral Immunity

Answer 1

The production of an antibody in response to an antigen. You come in contact with someone who is carrying an antigen, and it is passed on to you. It enters your body, you get sick. Your body creates an antibody to fight the disease, and you will not get the disease again.

Question 2

Primary Response

Answer 2

It takes 3-14 days for your body to build up enough antibodies to fight off the disease symptoms. During this time you will have physical symptoms of the antigen.

Question 3

Secondary Response

Answer 3

If the antigen enters your body a second time the fast response from your body thanks to your stored memory cells allows the animal to fight the disease without actively getting the symptoms.

Question 4

Active Immunity

Answer 4

This is developed by the use of a vaccination. The body is exposed to an altered version of the antigen, causing your body to create an antibody. The animal will not actively get the disease.

Question 5

Passive Immunity

Answer 5

Immunity that is passed from one animal to another. Most often from a mother to a child via colostrum in the milk. Passive immunity can last up to 6 months. It is important that the newborn receives this milk as soon after birth as possible.
