Intermediate Lymphatic Organs Quiz

Q1. Which structural arrangement is characteristic of the thymus?

• Red pulp and white pulp
• Follicles surrounding venous sinuses only
• Renal cortex and medulla
• Lobules with cortex and medulla

Q2. Which structures are characteristic of the thymic medulla?

• High endothelial venules
• Splenic sinusoids
• Hassall corpuscles
• Afferent lymphatic sinuses

Q3. Which lymph node region contains most lymphoid follicles?

• Cortex
• Medullary sinus only
• Hilum
• Fibrous capsule only

Q4. Which lymphocytes are especially concentrated in the lymph node paracortex?

• Neutrophils exclusively
• Megakaryocytes
• T lymphocytes
• Erythrocytes

Q5. Which compartment of the spleen contains lymphoid tissue organized around arterial branches?

• White pulp
• Trabecular connective tissue only
• Red pulp
• Splenic capsule only

Q6. What is a major function of splenic red pulp?

• Filter lymph from the lower limb
• Mature T lymphocytes
• Produce thyroid hormone
• Filter blood and remove aged erythrocytes

Q7. How does lymph normally enter a lymph node?

• Through the thymic cortex
• Through afferent lymphatic vessels
• Through the portal vein
• Through the splenic artery

Q8. How does lymph normally leave a lymph node?

• Through the central artery
• Through afferent vessels at the capsule
• Through efferent lymphatic vessels at the hilum
• Through thymic lobules

Q9. What is a major functional difference between lymph nodes and the spleen?

• Both receive lymph through afferent lymphatic vessels
• Lymph nodes monitor lymph, while the spleen monitors blood
• Lymph nodes monitor blood, while the spleen monitors lymph
• Both primarily filter cerebrospinal fluid

Q10. Which lymphatic tissues are positioned to sample antigens at mucosal surfaces?

• Bone periosteum
• Mucosa-associated lymphoid tissues
• Skeletal tendons
• Articular cartilage
