This is the molecule that sticks out on the surface of a pathogen
What is antigen
100
What is the cell that activates the cytotoxic T-cell?
What is helper t-cell
100
How do vaccines provide immunity against a disease?
What is introduction of antigen which leaves memory B and memory T cells for future infection
200
This is what the spleen does
Clean up old red blood cells.
200
This process raises the body's temperature in order to remove iron that bacteria need to survive at higher temps.
What is fever
200
This is anything that causes a disease
What is pathogen
200
The helper t-cell releases these chemicals to activate the cytotoxic t-cell
What is cytokines
200
What is an allergy
What is an immune response, treating the allergen as an antigen
300
This is what moves lymph around
What is movement of skeletal muscles and hydrostatic pressure
300
These are proteins that are secreted by virus-infected cells to interfere with viral functioning and infection of other cells.
What is interferons
300
This cell activates the B-cell that is attached to the antigen on a pathogen
What is helper t-cell
300
The helper t-cell must bind to what before becoming activated?
What is antigen on macrophage or another type of antigen-presenting cell.
300
Describe how antibiotic-resistant bacteria are being created.
What is natural selection
400
This can form when you have a blockage in a lymph vessel
What is an edema
400
These proteins attach to carbohydrate molecules on a pathogen's surface, allowing them to be easily picked up by a macrophage.
What is collectins
400
An activated B-cell divides through mitosis into these two cells
What is plasma and memory B-cells
400
This is NOT part of the cell-mediated response, but:
This is the type of cell that releases histamines that cause your blood vessels to dilate
What is mast cells
500
This is the function of a lymph node
What is they have a high concentration of lymphocytes (b and t cells) and so are able to clean the lymph of pathogens, preventing the spread of pathogens throughout the body.
500
Describe the inflammatory response
What is mast cells dilate blood vessels using histamines. The dilated blood vessels allow macrophages and other phagocytic cells to leak through and engulf the pathogens.
500
This is the purpose of plasma cells
What is produce antibodies to make the pathogen easier for recognition by macrophages.
500
What is the purpose of the cytotoxic t-cell?
What is destroy your infected cells by causing apoptosis.
