Question
Chapter 34, Problem 5WIO
Summary Introduction
To explain:
The reason why physicians may place a solution containing bovine tuberculosis bacteria into the patient’s bladder to treat the disease. Explain the reason why this treatment causes the patient’s immune system to launch an attack against the cancer cells. Write a prediction how bovine tuberculosis bacteria might help a patient’s immune system fight cancer.
Concept Introduction:
Bladder infection is caused by the infection of the lining of the cells in this organ. This infection can be caused by the micro-organisms like E.coli which adhere to the walls of the epithelial cells lining this organ. This organ stores the urine which is excreted from the human body.

Which statement best describes the difference between responses of effector B cells (plasma cells) and those of cytotoxic T cells? (A) B cells confer active immunity;cytotoxic T cells confer passive immunity. (B) B cells respond the first time a pathogen is present; cytotoxic T cells respond subsequent times. (C) B cells secrete antibodies against a pathogen; cytotoxic T cells kill pathogen-infected host cells. (D) B cells carry out the cell-mediated response; cytotoxic T cells carry out the humoral response.
. Which does NOT describe humoral immunity?
Group of answer choices
a. Antibodies are secreted by T-helper cells
b. Humoral immunity is effective against circulating toxins
c. Some B cells become memory cells
d. cytotoxic t cells can make antibodies
Cytotoxic T cells are immune cells that can eliminate some virus-infected cells.
a. Briefly describe how activated cytotoxic T cells can kill virus-infected cells.
