B.   It is divided into sections by capsular extensions called trabeculae.
C.   Its white pulp contains T-lymphocytes, B-lymphocytes, and macrophages.
D.   Its blood is supplied by the splenic artery and drained by the splenic vein.

A.   efferent lymphatic vessel.
B.   lacteal.
C.   afferent lymphatic vessel.

C.   nonspecific process that occurs in avascular tissue.
D.   nonspecific process that occurs in vascularized tissue.
Question #10
Circulation to the spleen demonstrates a(n)

B.   simple pathway, as its two capillary beds are separated by a portal vein.
C.   anastomosis, as its two capillary beds are separated by a portal vein.

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.   The axillary lymph nodes receive lymph from the breast and may contain cancer cells.
B.   With the removal of the breast, there is no further need for lymph drainage and filtering in that part of the body.
C.   The nerves that supply the axillary lymph nodes are often cut during the breast surgery.
D.   In removing the breast, the blood supply to the nodes is removed and they will inevitably cease to function.

B.   TRUE
Question #15
Blood colloid osmotic pressure is largely due to
A.   the proteins in the blood, and it promotes filtration.
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 filtration from arterioles.
D.   the proteins in the blood, and it promotes reabsorption.
E.   the high amount of water in the blood, and it promotes diffusion out of the capillaries.
Question #16
Chemotaxis is the process by which

B.   chemical messengers are secreted that stimulate the sensation of pain that accompanies inflammation.
C.   cells exit the blood by squeezing out between cells in the blood vessel wall.
D.   cells migrate along chemical gradients.
Question #17
Valves in veins
A.   are formed of the tunica media.
B.   cause venous blood flow to go in only one direction.
C.   make the use of a skeletal muscle pump unnecessary for venous blood flow.
D.   are found only in the largest veins.
E.   are the leading cause of high blood pressure.
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 happens at the venule end of a capillary bed and reabsorption happens in feeder arterioles.
C.   Filtration is driven by concentration gradients, whereas reabsorption depends on hydrostatic pressure.
D.   Filtration involves bulk flow of fluid out of the blood, whereas reabsorption is bulk flow back into the blood.
