Question #12
When women with breast cancer undergo surgery to remove the tumor or the entire breast, the axillary lymph nodes are often removed as well. Why?
A.   With the removal of the breast, there is no further need for lymph drainage and filtering in that part of the body.
B.   In removing the breast, the blood supply to the nodes is removed and they will inevitably cease to function.

B.   the pressure generated by the heart, and it favors osmosis into the arteriole end of the capillary bed.
C.   the high amount of water in the blood, and it promotes diffusion out of the capillaries.
D.   the high amount of water in the blood, and it promotes filtration from arterioles.

Question #17
Valves in veins
A.   are formed of the tunica media.
B.   cause venous blood flow to go in only one direction.
C.   are the leading cause of high blood pressure.
D.   make the use of a skeletal muscle pump unnecessary for venous blood flow.
E.   are found only in the largest veins.
Question #18
Which statement accurately compares filtration and reabsorption?
A.   The direction of filtration can be either into or out of the blood, but reabsorption always involves fluids entering the blood.
B.   Filtration involves bulk flow of fluid out of the blood, whereas reabsorption is bulk flow back into the blood.
C.   Filtration is driven by concentration gradients, whereas reabsorption depends on hydrostatic pressure.
