Select the correct statement about lymph transport. a. lymph transport depends on the movement of adjacent tissues, such as skeletal muscles. b. under normal conditions, lymph vessels are very high-pressure conduits. c. lymph transport is only necessary when illness causes tissue swelling. d. lymph transport is faster than that occurring in veins.

Option A, Lymph transport depends on the movement of adjacent tissues, such as skeletal muscles

Explanation:

The transport of lymphatic fluid through the lymphangions is dependent on the several other muscular functions such as skeletal muscle contraction, smooth muscle contraction etc.  

When smooth muscle and skeletal muscle work along with the semilunar valves, a pressure is build up that pushes the lymph fluid against the valves that  prevents back flow.  

Even though when the pressure in lymphatic tissue is low, fluid is passed on by the combined force of external muscular efforts.  

Hence, option A is correct
