D.   histamine
E.   complement
Question #7
Which is not correct regarding the spleen?
A.   Its blood is supplied by the splenic artery and drained by the splenic vein.
B.   It has an outer cortex and inner medulla.
C.   It is divided into sections by capsular extensions called trabeculae.
D.   Its white pulp contains T-lymphocytes, B-lymphocytes, and macrophages.
Question #8
A lymphatic capillary that picks up dietary lipids in the small intestine is called a(n)
A.   trabeculum.
B.   cisterna chyli.
C.   afferent lymphatic vessel.
D.   lacteal.
E.   efferent lymphatic vessel.

A.   nonspecific process that occurs in vascularized tissue.
B.   antigen-specific process that occurs in vascularized tissue.
C.   antigen-specific process that occurs in avascular tissue.
D.   nonspecific process that occurs in avascular tissue.
Question #10
Circulation to the spleen demonstrates a(n)
A.   anastomosis, as its two capillary beds are separated by a portal vein.
B.   simple pathway, as one artery delivers blood and one vein drains the organ.
C.   anastomosis, as one artery delivers blood and one vein drains the organ.
D.   simple pathway, as its two capillary beds are separated by a portal vein.
Question #11
Dendritic cells of the skin are derived from
A.   macrophages.
B.   monocytes.
C.   B-lymphocytes.
D.   neutrophils.
E.   T-lymphocytes.
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.   It is impossible to remove the breast without physically damaging the lymph nodes.
B.   The nerves that supply the axillary lymph nodes are often cut during the breast surgery.
C.   The axillary lymph nodes receive lymph from the breast and may contain cancer cells.
D.   In removing the breast, the blood supply to the nodes is removed and they will inevitably cease to function.
E.   With the removal of the breast, there is no further need for lymph drainage and filtering in that part of the body.

B.   FALSE
Question #15
Blood colloid osmotic pressure is largely due to
A.   the high amount of water in the blood, and it promotes filtration from arterioles.
B.   the proteins in the blood, and it promotes reabsorption.
C.   the high amount of water in the blood, and it promotes diffusion out of the capillaries.
D.   the proteins in the blood, and it promotes filtration.
E.   the pressure generated by the heart, and it favors osmosis into the arteriole end of the capillary bed.
Question #16
Chemotaxis is the process by which
A.   cells exit the blood by squeezing out between cells in the blood vessel wall.
B.   chemical messengers are secreted that stimulate the sensation of pain that accompanies inflammation.
C.   CAMs on leukocytes adhere to CAMs on endothelial cells of capillaries within injured tissues.
D.   cells migrate along chemical gradients.
Question #17
Valves in veins
A.   are the leading cause of high blood pressure.
B.   are formed of the tunica media.
C.   are found only in the largest veins.
D.   make the use of a skeletal muscle pump unnecessary for venous blood flow.
E.   cause venous blood flow to go in only one direction.
Question #18
Which statement accurately compares filtration and reabsorption?
A.   Filtration happens at the venule end of a capillary bed and reabsorption happens in feeder arterioles.
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.
D.   The direction of filtration can be either into or out of the blood, but reabsorption always involves fluids entering the blood.
