Mod:1 Lesson 11: What are the humoral and cellular immune responses?

Question 1

Match the following:
____ macrophages ingest antigens and display antigenic proteins on surface
____ macrophages partially digest infected body cell, and display antigenic proteins on surface
____ cytotoxic T lymphocytes destroy infected body cells
____ plasma cells secrete large quantities of antigen-specific antibodies

A. humoral immune response
B. cell-mediated immune response

Answer 1

Match the following:
A. humoral immune response____ macrophages ingest antigens and display antigenic proteins on surface

B. cell-mediated immune response____ macrophages partially digest infected body cell, and display antigenic proteins on surface

B. cell-mediated immune response____ cytotoxic T lymphocytes destroy infected body cells

A. humoral immune response____ plasma cells secrete large quantities of antigen-specific antibodies

Question 2

True / False Helper T lymphocytes secrete helper factor, which stimulates B lymphocytes to mature into plasma cells.

Answer 2

True

Question 3

True / False Helper T lymphocytes secrete interleukin 1, which suppresses the proliferation of cytotoxic T lymphocytes.

Answer 3

False

Question 4

True / False Memory cells are lymphocytes that remain in the body in a resting state, but are available to initiate a rapid immune response upon subsequent contact with an antigen to which they have already been exposed.

Answer 4

True

Question 5

Describe how the specific and nonspecific components of the immune system work together to eliminate antigens in the humoral response.

Answer 5

Lymphocytes and antibodies are the specific immune components that identify antigens for destruction by the nonspecific components, which include complement and macrophages.
