| What happens once a virus enters a cell? |
|
Definition
| it multiplies itslef and the cell busts and try to take over other cells |
|
|
Term
| Once a cell bursts and viruses are released, they need to be killed by white blood cells called _____. |

| What happens when a macrophage eats a virus/ |
|
Definition
| it takes an antigen from the virus and displays it on its surface |
|
|
Term
| What is the protein called where an antigen lies on the surface of the macrophage? |
|
Definition
|
|
Term
| where will the macrophage eventually go? |
|
Definition
|
|
Term
| What are inside lymph nodes? What does a macrophage do once iside a lymph node |
|
Definition
| t cells and b cells; bumps into the t cells and b cells |
|
|
Term
| The T cells have ______that are supposed to match up to only one _____on the macrophage. |
|
Definition
|
|
Term
| When the macrophage binds to one antigen, what happens to the T cell? |
|
Definition
| it is activated and clones itself |
|
|
Term
| What are the three types of T cells? |
|
Definition
| memory, killer, and helper |
|
|
Term
| What do memory T cells do? |
|
Definition
| they stay in the body for the rest of a lifetime to make sure you never get sick again |
|
|
Term
| What do killer T cells do? |
|
Definition
| they go around the body and bump into cells and eventually finds a cell that matches its receptor and sprays the cell with a chemical called perferin which kills the cell and all viruses inside |
|
|
Term
| Killer t cells are also called_____ |
|
Definition
|
|
Term
| What does a Helper t cell do? |
|
Definition
| it goes around the body and sprays a chemical called cytokines which cause a cell to multiply and spray white blood cells |
|
|
Term
| What do helper T cells help increase? |
|
Definition
|
|
Term
| helper t cells are the cells that _____infects. |
|
Definition
|
|
Term
| There are still viruses that need to be killed that macrophages didn't get. Which is more difficult to activate B cells or T cells? |
|
Definition
|
|
Term
| What two things must happen in order for a B cell to be activated? |
|
Definition
| a virus must go into a lymph node and bump into B cells and eventually finds a cell that matches its receptor and the helper t cell has to come into the lymph node and spray the B cell with cytokines and then the B cell is activated and clones itself |
|
|
Term
| What are the two types of B cells? |
|
Definition
| memory b cells and plasma b cells |
|
|
Term
| How do plasma b cells create the ultimate weapon against a virus? |
|
Definition
| there are y shaped receptors that are released and float away. these y shaped receptors are made by plasma b cells and they are called antibodies |
|
|
Term
|
Definition
| they stick to antigens on viruses and when many antibodies start to stick on a virus, they form one virus stuck together called an agglutination |
|
|
Term
| What happens to a virus when it becomes an agluttanation? |
|
Definition
|
|
Term
| What happens to the agglutunations? |
|
Definition
| they are eaten by a macrophage |
