Topic: Lymphoid Organs and Tissues
Multiple Choice Questions
Q1. Lymphoid organs are primarily associated with the:
- Digestive system
- Immune system
- Respiratory system
- Excretory system
Q2. Which of the following is classified as a primary lymphoid organ?
- Spleen
- Lymph nodes
- Bone marrow
- Tonsils
Q3. The thymus gland is particularly important because it is the site where:
- B-lymphocytes originate
- T-lymphocytes mature
- Red blood cells are destroyed
- Antibodies are stored permanently
Q4. The spleen, as a secondary lymphoid organ, mainly functions to:
- Produce all blood cells
- Filter blood and help mount immune responses against blood-borne antigens
- Digest food
- Regulate hormone levels
Q5. Lymph nodes are important secondary lymphoid organs because they:
- Filter lymph and act as sites where immune responses can be initiated
- Produce insulin
- Store excess fat only
- Have no role in immunity

Long Answer Questions
Q10. Describe the primary lymphoid organs (bone marrow and thymus), explaining their specific roles in the development of the immune system.
Q11. Discuss the secondary lymphoid organs (spleen, lymph nodes, tonsils, etc.), explaining how they support the body's immune response against pathogens.
APPLICATION / ANALYSIS
Q12. During a throat infection, a doctor notices that a patient's tonsils are swollen and tender. Using your understanding of lymphoid tissue, explain why the tonsils react this way during an infection.
Q13. A patient with a damaged thymus gland from birth shows a significantly weaker immune response compared to healthy individuals of the same age. Explain, using your understanding of lymphoid organs, why thymus damage would have such a serious effect on immunity.
