Question #1
Lymph vessels are vessels that are separate from the circulatory system but are closely associated with capillary beds. Which one of the following statements correctly describes the role that lymph vessels play in bulk flow?
a. Lymph vessels actively pump proteins into the interstitial fluid to create the diffusion gradients that power bulk flow.
b. Lymph vessels absorb extra fluid from the interstitial fluid that is not returned to the blood through the capillaries via bulk flow.
c. Lymph vessels secrete extra fluid into the interstitial fluid to encourage the pressure gradients that power bulk flow.
Question #2
In the preceding diagram, three areas of the vessels system are highlighted by boxes labeled A, B, and C.Which one of the following statements correctly describes how flow velocity differs among these three areas?
a) Areas B and A have roughly equivalent flow velocities, but Area C has a lower flow velocity.
b) Flow velocity decreases steadily as the blood moves from Area B to Area C to Area A.
c) Areas B and A have roughly equivalent flow velocities, but Area C has a higher flow velocity.
d) Flow velocity increases steadily as the blood moves from Area B to Area C to Area A.

1)
b) lymph vessels absorb extra fuild from the interstial fluid that is not returned to the blood through the capillaries via bulk flow.
Lymphs is the extracellular fluid that is infiltrated from blood. Gets deposited in interatial fluid which is collected and transported to different areas by lymph bessels.
2)
b) flow velocity decreases steadily as the blood moves from area B to area C to area A.
