Question

According to the National Cancer Institute, why are lymph nodes distributed in the neck, underarm, chest, abdomen, and groin?

a. Lymph nodes are randomly distributed in the body.
b. Breathing creates a pressure gradient, pulling lymph through the lymphatic system.
c. Lymph nodes are primarily found in areas prone to infections.
d. The distribution of lymph nodes is genetically determined.

Answer 1

Lymph nodes are distributed in the neck, underarm, chest, abdomen, and groin because they serve as major staging areas for the development of critical immune responses. They remove debris and pathogens from the lymph and filter bacteria that infect the interstitial fluid.

Step-by-step explanation:

Lymph nodes are distributed in the neck, underarm, chest, abdomen, and groin because they serve as major staging areas for the development of critical immune responses. They function to remove debris and pathogens from the lymph, filtering any bacteria that infect the interstitial fluid and kill them. Lymph nodes are commonly found in areas prone to infections, as they play a crucial role in the body's immune response.
