The Lymphatic and Immune System Quiz

Spleen Location

• The spleen is situated in the upper left quadrant of the abdomen, behind the stomach and under the diaphragm.
• It is connected to the cardiovascular system via the splenic artery and vein.

Thymus Function

• The thymus plays a critical role in the development and maturation of T lymphocytes (T cells), which are essential for adaptive immunity.
• It is most active during childhood and gradually decreases in size and function with age.

Role of Tonsils and Adenoid

• Tonsils and adenoids are lymphoid tissues that help protect the respiratory and gastrointestinal tracts from pathogens.
• They act as the first line of defense by trapping and filtering out bacteria and viruses, contributing to the body's immune response.

Bone Marrow Location

• Bone marrow is found within the hollow spaces of bones, primarily in the pelvis, vertebrae, and long bones such as the femur.
• It is categorized into red marrow, which produces blood cells, and yellow marrow, which stores fat.

Primary Function of the Lymphatic System

• The lymphatic system is integral for maintaining fluid balance in the body, draining excess lymph from tissues and returning it to the bloodstream.
• It also plays a key role in immune system function by transporting lymph, which contains white blood cells, throughout the body.
