Innate Immunity
True or False
Innate Immunity is the first line of defense
True
These cells are produced by B cells to neutralize specific pathogens
What are antibodies
These structures act as the filters for the immune system
What are lymph nodes
The first line of defense including skin and mucas
What are physical barriers
The protein that marks the surface of viruses
What are antigens
The primary physical barrier of the human body
What is the skin
This type of lymphocyte matures in the bone marrow & produces antibodies
What are B cells
This fluid travels through lymphatic vessels and contains white blood cells
What is lymph
This sticky substance lines the respiratory and digestive tracts to trap dust and germs
What is Mucas
Unlike T cells these cells bind directly to free floating proteins
What are B cells
This response is characterized with redness, heat, swelling, & pain
What is inflammation
This type of lymphocyte matures in the Thymus and directly kills infected host cells
What are T cells
The lymphatic system relies on this type of body movement to keep fluid flowing
What is exercise
The enzyme that attacks the cell walls of certain bacteria
What is lysozyme
The maturation site of T cells
What is the thymus
These proteins act as chemical messengers, coordinating chemical responses
What are Cytokines
These specific T cells releases signals to activate both B cells and Killer T cells
What are helper T cells
These are the patches of lymphatic tissue located in the back of the throat
What are tonsils
The tiny hair like structures that line the respiratory tract and that carry trapped particles out of the system
What are cilia
This type of T cell uses chemical signals called cytokines to coordinate a response of other white blood cells
What are helper T cells
This group of proteins circulates in the blood to help clear out pathogens.
What is the complement system
This is the process where a specific B or T cell multiplies rapidly after recognizing its specific antigen
What is clonal expansion
This is the largest lymphatic organ that filters blood rather than lymph
What is the spleen
The chemical in the stomach that creates an environment to harsh for most swallowed pathogens
What is stomach acid
These T cells stick around for years to mount a rapid-fire attack if the same pathogen ever returns.
What are memory T cells
