d. Both x A x and x B.
ANS: D
The xfunction x of x the x immune x system x is x to x recognize x self x from x nonself x and x defend x the
x body xagainst x nonself. x Such x a x system x is x necessary x for x survival. x The x immune x system
x also x has xnonspecific xeffector xmechanisms xthat xusually xamplify xthe xspecific xfunctions.
xNonspecific x components xof xthe ximmune xsystem xinclude xmononuclear xphagocytes,
xpolymorphonuclear xleukocytes, xand xsoluble xfactors x(e.g., xcomplement).

d. recovery x from x infectious x disease.
ANS: C
The xdesirable xconsequences xof ximmunity xinclude xnatural xresistance, xrecovery, xand xacquired
x resistance xto xinfectious xdiseases. xA xdeficiency xor xdysfunction xof xthe ximmune xsystem xcan
x cause x many x disorders. x Undesirable x consequences x of x immunity x include x allergy,
x rejection x of xa xtransplanted xorgan, xor xan xautoimmune xdisorder.

5. The x immune x system x has x various x distinctive x characteristics x except;
a. specificity.
b. memory.
c. mobility.
d. noncooperation x among x different x cells.
ANS: D
The x immune x system x is x composed x of x a x large, x complex x set x of x widely xdistributed
x elements, xwith xthe xdistinctive xcharacteristics xof xspecificity, xmemory, xmobility, xreplicability,
xand x cooperation xamong xdifferent xcells xor xcellular xproducts. xSpecificity xand xmemory xare
x characteristics xof xlymphocytes xin xthe ximmune xsystem. xNonspecific xelements xof xthe
ximmune x system xdemonstrate x mobility. xIn x addition, xspecific xand xnonspecific xcellular
xcomponents xof xthe ximmune xsystem xcan xreplicate. xCooperation x is xrequired xfor xoptimal
xfunctioning, x and x interaction x involves x specific x cellular x elements, x cell x products, x and
x nonlymphoid x elements.

a. immediate x hours x after x conception
b. second x month x of x gestation.
c. second x trimester x of x gestation.
d. periods x of x severe x anemia x in x children.
ANS: A
The x sites x of x blood x cell x development, x or x hematopoiesis, x follow x a x definite x sequence x in
x the xembryo x and xfetus. xHematopoiesis x occurs xin xthe xyolk xsac xduring xthe xsecond x month xof
xgestation.
DIF: Cognitive x Level: x II
7. The x sequence x of x blood x cell x development x in x the x embryo x and x fetus x is
a. yolk x sac, x liver-spleen, x bone x marrow.
b. yolk x sac, x bone x marrow, x liver/spleen.
c. liver-spleen, x yolk x sac, x bone x marrow.
d. bone x marrow, x liver-spleen, x yolk x sac.
ANS: A
, The x first x blood x cells x are x primitive x red x blood x cells x (erythroblasts; x RBCs) x formed x in
x the xislets x of x the x yolk x sac x during x the x first x 2 x to x 8 x weeks x of x life. x Gradually, x the x liver
x and x spleen xreplace x the x yolk x sac x as x the x sites x of x blood x cell x development. x By x the
x second x month x of xgestation, x the x liver x becomes x the x major x site x of x hematopoiesis,
x and x granular x types x of xleukocytes x have x made x their x initial x appearance. x The x liver
x and x spleen x predominate x from xabout x 2 x to x 5 x months x of x fetal x life. x In x the x fourth
x month x of x gestation, x bone x marrow x begins xto x produce x blood x cells. x After xthe x fifth
x fetal x month, x bone x marrow x begins x to x assume x its xultimate x role x as x the x primary x site
