Bio Unit 4 Sec 2 #5: Lecture 35

QuestionAnswer
Anything the body recognizes as something that should not be there Antigen
B cells and T cells are: Lymphocytes
B-Cells produce _______ Antibodies
2 types of T-Cells: Cytotoxic; Helper
_______ T-Cells seek out and destroy virally infected cells Cytotoxic
______ T-Cells stimulate TC cells and B-Cells Helper
Special cells of the immune system that recognize and remember specific parts of pathogens called antigens Lymphocytes
_______ are surface proteins or glycoproteins on pathogens that are unique to each pathogen Antigen
When lymphocytes encounter a new pathogen, an ______ response is triggered to fight it and the lymphocytes begin to ______ to fight the pathogen Immune; Multiply
With Adaptive Immunity, lymphocytes produce _______ and defensive chemicals as a defensive response to a pathogen Antibodies
It takes ______ days to start an immune response 1-2
Lymphocytes that recognize a specific pathogen and remain in the body in case the pathogen enters the body again. Memory Cells
In adaptive immunity, the memory cells produce an immune response much faster and the pathogen is _______ before it can make you sick Destroyed
Humoral Immune Response fights _______ infections Bacterial
B-Cells and Antibodies are parts of the _______ Immune Response Humoral
Each B-Cell has millions of identical B-Cell ______ on its surface that recognize some type of antigen exists Receptors
When________ become activated when they come in contact with a particular antigen, they produce _______ B-Cells; Antibodies
These are produced when B-Cells are activtated Antibodies
Antibodies are ______ that have an antigen binding region Proteins
Interaction with an ________ stimulates the production of a specific B Cells into plasm cells that produce antibodies that ________ the antigen Antigen; Recognize
The increased recognition of antigen by phagocytic cells (cells that attack the antigen) is called: Opsonization
Vasodilation that brings more blood, nutrients, leukocytes and defensive chemical to the site of infection is called: Inflammation
The complement cascade begins resulting in inflammation and membrane attack complexes Activation of Complement
When Pathogens are clumped together and attacked by defensive chemicals and phagocytes Agglutination
When antibodies surround toxins so they cannot harm tissues Neutralization

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
