Adaptive immunity Flashcards
1
Q
What is adaptive immunity?
A
It is a specific immune response that happens gradually in response to pathogen is after they entered the body
2
Q
What cells are involved?
A
B. Lymphocytes and T lymphocytes
3
Q
where are B and T cells Found and made?
A
- B. Lymphocytes are made and matured in the bone marrow
- T lymphocytes are made in the bone marrow and matured in the thymus
- They stored in the lymph nodes
4
Q
what is the function of B cells and T cells?
A
- B lymphocytes are involved in the humoral response which is when pathogens are in the body is fluid
- T lymphocytes are involved in cell mediated responses which is when the pathogen is in another cell
5
Q
what are the five stages of humoral immunity?
A
- Pathogen enters. The body is fluid.
- B cells with complimentary receptors bind to the pathogen is antigen.
- t-helper cells activate the B cell
- The bee cells divide by mitosis this is known as clonal expansion
- The bee cells than differentiate into two types of cells: the memory cells, and the plasma cells
6
Q
what did B plasma and memory cells do?
A
- B plasma cells make antibodies which attach and destroy pathogens
- B memory cells. Remember the pathogen is antigen to make the response faster, if it every enters the body.
7
Q
what are the five stages of cell mediated response??
A
- pathogen is inside a cell in the body
- The infected cell holds the antigen out on the surface, making it an antigen presenting cell.
- The complimentary T cells that bind to the antigen.
- This automatically activate the sale and it divides by mitosis.
- The cell differentiates into T-helper cells and T-killah cells.
8
Q
What does tea, healthy cells and tea killer cells do?
A
- T-helper cells activate clonal expansion
- Tea killer cells, kill the infected cell
9
Q
What are the four types of immunity?
A
- Active (you make the antibodies)
- Passive (the body uses ready-made antibodies)
- Natural
- Artificial (where are you are given something that triggers a response e.g. a vaccination
