Question 11
Needs Grading
Reference Figure 14-3: State the seven major PAIRED groups of lymph
nodes. Why are these nodes located in or near the head and extremities?
Selected
Answer:
submaxillary nodes, cervical nodes, axillary nodes, cubital nodes, Iliac nodes,
Inguinal nodes, popliteal nodes.
Breaks in the skin, with entry of pathogens, are much more likely to occur in
the arms or legs or head rather than in the trunk. If these pathogens get to the
lymph, they will be destroyed by the lymph nodes before they get to the trunk
and before the lymph is returned to the blood in the subclavian veins.
Correct
Answer:
Submaxillary nodes; Cervical nodes; Axillary nodes; Cubital
nodes; Iliac nodes; Inguinal nodes; Popliteal nodes. Breaks in the
skin, with entry of pathogens, are much more likely to occur in
the arms or legs or head rather than in the trunk. If these
pathgens get to the lymph, they will be destroyed by the lymph
nodes before they get to the trunk and before the lymph is
returned to the blood in the subclavian veins.
