Question

What is the function of each lymph organ?

Options:
a) Spleen, tonsils, thymus, red bone marrow
b) Tonsils, spleen, red bone marrow, thymus
c) Red bone marrow, thymus, tonsils, spleen
d) Thymus, red bone marrow, spleen, tonsils

Answer 1

Each lymph organ has a specific role: red bone marrow matures blood cells, the thymus gland is the site of T cell maturation, tonsils trap and fight pathogens, and the spleen filters blood and supports immune responses.

Step-by-step explanation:

Functions of Lymph Organs:

The lymphatic system includes several important organs, each with its own set of functions:

• Red bone marrow is where hematopoietic stem cells differentiate and mature into various types of blood cells, including B and T lymphocytes. B cells mature here, while T cells begin their maturation process in the marrow before completing it in the thymus.
• The thymus gland is responsible for the maturation of T cells or T-lymphocytes, which are crucial for the body's adaptive immune response.
• Tonsils, comprising different sets such as palatine and pharyngeal tonsils, are part of a group called Waldeyer's ring. They trap and help fight off pathogens entering through the mouth and respiratory tract.
• The spleen serves multiple functions, including filtering the blood by removing worn-out red blood cells, capturing pathogens, and playing a role in immune responses to blood-borne pathogens. The spleen is populated with lymphocytes, macrophages, and dendritic cells.
