lymph is moved through lymph vessels by which two of the following?
□ peristaltic contractions of the gl tract
□ respiratory pump
□ skeletal muscle contraction around the lymphatic vessel walls
□ skeletal muscle pumps
□ pumping of lymph by the heart

Explanation:

Lymph movement in lymph vessels is aided by the respiratory pump which creates pressure changes during breathing and skeletal - muscle contractions around lymphatic vessel walls that squeeze the vessels to push lymph along. Peristaltic contractions of the GI tract are related to digestion and not lymph movement. The heart does not pump lymph. There is no such thing as skeletal - muscle pumps in the context of lymph movement in the way described here.

Answer:

B. respiratory pump, C. skeletal muscle contraction around the lymphatic vessel walls
