Question

Which one of the following regions of human body does NOT have maximum lymph nodes?

• A. Neck
• B. Armpit
• C. Groin
• D. Abdomen

Hint:

Maximum lymph nodes are present in neck, armpit, and groin regions.

Answer 1

The Correct Option is D

Step 1: Understanding lymph nodes distribution.
Lymph nodes are small immune organs distributed throughout the body. However, they are not evenly spread. Certain regions have a higher concentration due to their role in filtering lymph from large areas of the body.
Step 2: Regions with maximum lymph nodes.
The neck (cervical), armpit (axillary), and groin (inguinal) regions contain a large number of lymph nodes. These areas drain lymph from major body parts such as limbs, head, and thorax.
Step 3: Analysis of options.
(A) Neck: Contains cervical lymph nodes in large numbers.
(B) Armpit: Houses axillary lymph nodes, one of the largest lymph node groups.
(C) Groin: Contains inguinal lymph nodes, which are also numerous.
(D) Abdomen: Does not have a maximum concentration of lymph nodes compared to the above regions.
Step 4: Conclusion.
The abdomen does not contain the maximum number of lymph nodes; hence, it is the correct answer.
