The chemical signals at location 3 that activate other cells are called
a. cytokines c. antibodies
b. antigens d. neutrophils
A. Cytokines
What are two differences between T cells and B cells
B cells: Humoral Immunity, secrete antibodies, detect antigens on their own, attack antigens before they enter cells
T cells: Cell-mediated immunity, only detect antigens presented by other cells, attack infected body cells, do not secrete antibodies
Which of these is part of the acquired/specific immune response?

b. is comprised of red blood cells.
c. enters the lymph capillaries.
d. contains antibodies
A. is recycled into the blood vessels
The diagram above depicts
a. innate immunity c. cell-mediated immunity
b. humoral immunity d. artificial immunity
c. Cell Mediated immunity
what role do phagocytic cells play in the immune response?
Phagocytic cells engulf and destroy foreign particles before they enter the body cells.
Which of the following is considered a lymph nodule rather than an organ?
a. Tonsils c. thymus
b. spleen
B. Spleen
_____________ is the location of T cell Maturation
Thymus
In which of the following areas do enzyme secretions play the greatest role in eliminating pathogens?

____________ is found in lymph organs but not lymph nodules
Thymus
Which of the following is an external barrier in the innate/nonspecific defenses?

a. antibody c. lymphocyte
b. memory cell d. antigen
d. Antigen
How does inflammation aid in the immune response?
Inflammation allows leukocytes to arrive quickly and discourages use of the injured area throw swelling and pain.

The diagram above depicts
a. innate immunity c. cell-mediated immunity
b. humoral immunity d. artificial immunity
b. Humoral Immunity
what is the function of a cytotoxic T cell?
