b. "The flow of lymph is slow, compared with that of the blood."
c. "One of the functions of the lymph is to absorb lipids from the biliary tract."
d. "Lymph vessels have no valves; therefore, lymph fluid flows freely from the tissue spaces into the bloodstream."
ANS: B
The flow of lymph is slow, compared with flow of the blood. Lymph flow is not propelled by the heart but rather by contracting skeletal muscles, pressure changes secondary to breathing, and contraction of the vessel walls. Lymph does not absorb lipids from the biliary tract. The vessels do have valves; therefore, flow is one way from the tissue spaces to the bloodstream.
