Chapter 20, Problem 2d
Mark the following statements as true or false. If a statement is false, correct it to make a true statement.
The thymus is the site of maturation of B cells.
Verified step by step guidance1
Step 1: Understand the role of the thymus in the immune system. The thymus is primarily responsible for the maturation of T cells, not B cells. T cells are a type of lymphocyte that play a critical role in adaptive immunity.
Step 2: Learn where B cells mature. B cells mature in the bone marrow, which is distinct from the thymus. This is why the statement in the problem is false.
Step 3: Correct the false statement. The corrected statement should read: 'The thymus is the site of maturation of T cells.'
Step 4: Review the distinction between T cells and B cells. T cells are involved in cell-mediated immunity, while B cells are responsible for humoral immunity (antibody production).
Step 5: Confirm your understanding by revisiting the anatomy and physiology of the immune system, focusing on the roles of the thymus and bone marrow in lymphocyte development.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Thymus Function
The thymus is a specialized organ of the immune system where T cells mature. It plays a crucial role in developing the adaptive immune response by producing T lymphocytes, which are essential for recognizing and responding to pathogens.

Introduction to the Thymus
B Cell Maturation
B cells, another type of lymphocyte, mature primarily in the bone marrow, not the thymus. Once matured, B cells are responsible for producing antibodies that help neutralize pathogens and facilitate their destruction.

Immune System Overview
The immune system consists of various cells and organs that work together to defend the body against infections. Key components include T cells, B cells, and organs like the thymus and bone marrow, each playing distinct roles in immune responses.

Textbook Question
Your friend tests her snake-wrangling skills on an eastern diamondback rattlesnake, and is bitten and envenomated (injected with the snake's venom). In the emergency department, doctors administer the antivenin CroFab, which contains antibodies to the toxins in snake venom. Is this an example of active or passive immunity? Will this confer any lasting protection to your friend?
