28
Q

What is the key developmental consideration regarding lymph nodes in children?

A

Lymph nodes are relatively larger and palpable.

29
Q

What do lymphocytes do when exposed to pathogens in lymph nodes?

Q

What characteristic do lymph nodes have in children?

A

They are relatively large and more easily palpable.
