Question

Draw the structure of Lymph node and label the parts.

Hint:

Remember: Lymph node → Capsule + Cortex + Medulla + Vessels.

Answer 1

Concept: A lymph node is a small, bean-shaped structure that plays an important role in the immune system.
Step 1: Main parts of lymph node.

• Capsule
• Cortex
• Medulla
• Germinal center
• Afferent lymphatic vessels
• Efferent lymphatic vessel
• Hilum

Step 2: Diagram (labelled).
\[ \begin{array}{c} \text{Afferent lymphatic vessels} \rightarrow \bigcirc
\text{Outer layer: Capsule}
\text{Cortex (with germinal centers)}
\text{Medulla (inner region)}
\text{Efferent lymphatic vessel at hilum} \end{array} \]
Step 3: Conclusion.
Thus, the lymph node consists of cortex and medulla enclosed by a capsule with lymphatic vessels entering and leaving it.
