Question

T cells not activated in the lymph nodes (via dendritic cells) exit the LN through the _____

a) Arteries
b) Efferent lymphatics
c) Capillaries
d) Veins

Answer 1

T cells exit the lymph node through the efferent lymphatics after not being activated by dendritic cells within the node.

Step-by-step explanation:

T cells that have not been activated in the lymph node (via dendritic cells) exit the lymph node through the efferent lymphatics. The lymph node, a critical part of the immune system, filters the lymph fluid that enters through the afferent lymphatic vessels. After the lymph fluid has been filtered and immune cells such as T cells have interacted with presenting cells like dendritic cells, it leaves the lymph node via the efferent lymphatic vessels.
