Question

Once collected, lymph ultimately drains into __________.

Answer 1

Once collected, lymph ultimately drains into venous circulation.
<u />Lymph goes from terminal lymphatic ducts into venous circulation through the subclavian veins.
Lymph is not filtered or detoxicated yet at this point, and it doesn't go to arterial circulation because that would just distribute it all over the body, instead of just the heart.
