Immune System

QuestionAnswer
Cell fragments essential to blood clotting Platelets
Defend body against disease, increase dramatically during infection White blood cells
Transport oxygen Red blood cells
Medium for transporting material in the blood Plasma
Undifferentiated cells in red bone marrow Stem cells
T-Cells, B-cells, NK cells, NKT cells Platelets
Erythrocytes Red Blood Cells
(Neutophil, Basophil, Eosinophil) Granulocyte White Blood Cell
(Lymphocyte, Monocyte) Agranulocytes White Blood Cell
Which cell(s) migrate through vessel walls White Blood Cells
Which cell(s) do not migrate through vessel walls Red Blood Cells, Platelets
MHC major histocompatibility
A molecule, often found on the surface of a pathogen, recognized as foe Antigen
Detection is: when a macro-phage encounters, engulfs, and digests an invader
MHC markers: When a piece of invader is placed on a macro-phages surface
The marco-phage presents the antigen to a helper T cell and then: secretes a chemical to activate the T cell
The Antibody mediated response activated by effector T cells is: Naive B Cells
The Cell mediated response activated by effector T cells is: Naive Cytotoxic T cell
What do antibodies do? (TAC) Neutralize foreign toxins Trigger release of more complement Attract more macro-phages
Name the steps of the immune system to an attack: 1. Threat 2. Detection 3. Alert 4. Alarm 5. Building specific defenses 6. Defense
AntiBody Response attacks: Pathogens or toxins outside of cells
Cell Based Immunity (T Lymphocyte) targets: Cells infected with pathogen
Memory Cells: Form after a pathogen attack, provide quick response if the invader returns
Memory Cells are stored in: bone marrow and thymus
Too little of T suppressor: Allergies, autoimmune disease, graft rejection, inflammatory bowel disease
Too much of T suppressor: Cancer, infectious disease
Monocytes mature into: resident macrophages once taken up in tissues

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:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
