Question

multiple choice question
lymph enters a lymph node via ____ vessels and exits a lymph node via ____ vessels.

efferent, afferent
afferent, efferent

Explanation:

To solve this, we recall the anatomy of lymph nodes. Afferent lymphatic vessels carry lymph into the lymph node, while efferent vessels carry it out. So the correct pairing is afferent (entry) and efferent (exit).

Answer:

B. afferent, efferent (assuming the second option is labeled B; if the options were just the two, the correct one is "afferent, efferent")
