Biology immune Syste

TermDefinition
3rd line of defense Circulatory System which sends chemicals to coordinate an attack and to transport WTC to infection
2nd line of defense Mucus membranes which are hair like cilia with sticky liquid that trap pathogens
First line of defence Skin, largest organ that physically blocks invading pathogens. Also skin creates non living environments for pathogens
Immune system Body system that fights off infections and pathogens
germ theory Microorganisms cause diseases
Bacteria releasing chemicals that are toxic to the host or by destroying healthy body cells
Viruses Take over a healthy cell forcing ti to stop its natural activities and produce more viruses
Fungi Pierces healthy cells and take the cell's nutrience
Protozoa Needs healthy cells to complete life cycle; preys on cells
Parasites Grow and feast on a host either kills the host or drains bodies resources without killing host
Pathogens are spread by Direct and Indirect contact
Examples of Direct contact Rabies and HIV
Examples of Indirect contact Surfaces of objects and air
Pathogen Something that causes disease
Vector is something that carries a pathogen and transmits it into a healthy cell
How to basophil cells react when a pathogen is in the body IT creates chemicals that cause inflammation in bloodstream
2 types of lymphocytes T cells destroy cells and B cells produce proteins that inactivate pathogens that havnt infected the body yet
Three types of proteins to fight off pathogens Complement proteins/antibodies/interferons
Complement proteins burst pathogen, make it more noticeable, or weaken membrane
Antibodies MAde by B cells and they clump pathogens, make the pathogens ineffective or membrane weak
Interferons prevent pathogens from multiplying
2 Types of Immunity Passive and active
Passive immunity Passed through genetics (DNA) or inherited immunity (mother's milk or umbilical cord
Active immunity Occurs when pathogens effet cells where the immunity prevents the body from getting sick by the same pathogen
Specific response Happen at a cellular level. Specific responses on slightly different for each pathogen
Nonspecific response occur in the same way to fight of pathogens
Inflammation Swelling, redness, itching, warm, and its purpose is to not allow more pathogens to enter through skin
Fever Increase body temp and help body my increasing the activity of WBC
Antigens are ID tags for surface of cells and viruses that help identify foreign/infected cells or virus
Memory cells specialized T and B cells that provide acquired immunity because they remember an antigen that has previously invaded your body
Cellular immunity A pathogen with antigens are swallowed by phagocyte when a T cell appears and attaches to the antigen. The T cell is activated and when replicated becomes either a memory or activated where the activated kill Phagocyates
Basophil Makes chemicals that cause inflammation in blood stream
Mast cell Makes chemicals that cause inflammation in other body tissues
Neutrophil engulfs pathogens and foreign invaders; phagocyte
Macrophage Engulfs dead or damaged body cells and some bacteria; phagocyte
Lymphocyte Destroys infected body cells or produces proteins that inactivate pathogens
Eosinophil Injects poisonous packets into parasites, such as protozoa
Antiseptics Kill pathogens outside the body;chemicals
Antibiotics target bacteria or fingi
antibiotic resistance occurs when bacteria mutate so that they are no longer affected by antibiotics
Allergy AN over sensitivity to a normally harmless antigen
Allergens Are antigens that cause an allergic reaction
Anaphylaxis condition that occurs when the immune system releases a large amount of histamines which causes airways to tighten and blood vessels to become expanded
Autoimmune diseases are diseases where the body cant tell which cells are healthy and which ones are not. Body starts attacking its own cells

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.
