Exam 33: Adaptive Immunity

B cells play an important role in humoral immunity.

An antibody consists of two heavy and one light polypeptide chains.

IgM is the most predominant class of immunoglobulins in the body.

A person without a functioning immune system would not benefit from an injection of antibodies developed by someone else.

The type of immunity produced by vaccination would be _____ immunity.

Describe the development and activation of B cells.

Match each type of specific immunity with its description or example. -After exposure to hepatitis A, a person is given a gamma globulin (IgG) shot to keep him from getting hepatitis

Memory cells do not actually produce antibodies.

If a person had a nonfunctioning immune system, what types of adaptive immunity (artificial, natural, active, and passive) could be beneficial and which would not be beneficial or even harmful?

Match each term with its corresponding definition. -Substance produced by the body that destroys or inactivates a specific antigen

Each light chain in an antibody molecule contains a constant region that consists of 446 amino acids.

Antigens activate B cells.

The complement system can be activated by:

In an antibody the light chain makes up the variable region and the heavy chain makes up the constant region.

The letters "CD" following a T cell stand for "cellular diversity."

B cells are named after a structure in birds.

The heavy chains in an immunoglobulin molecule are about twice as long and weigh about twice as much as light chains.

In the first stage of their development, B cells are known by all the following terms except _____ B cells.

Steven had mumps as a child. Why did he not experience symptoms at the age of 41 after he was again exposed to the mumps virus?
