levels iof istructural iorganization iand ibody isystems i-
iCorrect iAnswer-chemical i>> icellular i>> itissue i>>

iorgan i>> iorgan isystem i>> iorganismal



chemical ilevel i- iCorrect iAnswer--atoms= ismallest
iunit iof imatter

-atoms imake imolecule i
-DNA iis ismalles iunit
-based ion iCHONP i(carbon, ihydrogen, ioxygen,
initrogen, iphosphorus)



cellular ilevel i- iCorrect iAnswer--two ior imore isimilar
imolecules

-cell= ismallest istructural iand ifunctional iunit iof ithe
ihuman iorganism

-cell imembrane i(barrier), inucleus, iand icytoplasm
iare ithe iadvantages iof ia icell



tissue ilevel i- iCorrect iAnswer--tissues= igroup iof
icells iand imaterials isurrounding ithem ithat iwork

itogether ito iperform ia iparticular ifunction

-two idiff itypes iof icells iput itogether ieach ihaving ia
ispecific ifunction

-4 itypes
1. iepithelial itissue i(cover, iline, iglands)

,2. iconnective itissue i(connecting, isupporting,
iprotecting ivital iorgans, idistribute iblood)

3. imuscle itissue i(generate iforce ito icontract/relax)
i(20-30% iaffective i(rest igiven ioff ias iheat))

4. ineuron/nervous itissue i(transmits ielectrical iinfo
ifrom ione ilocation ito ianother... iacross isynapses)



organ ilevel i- iCorrect iAnswer--combine itwo ior imore
itissues

-provide ispecific ifunction i
-recognizable ishape

organ isystem i- iCorrect iAnswer--related iorgans iwith
icommon ifunction

-examples= idigestive isystem, icirculatory isystem
-11 iorgan isystems iin ithe ibody

organismal ilevel i- iCorrect iAnswer-combine iorgan
isystems iand ihave ithem iwork itogether



systems iof ithe ihuman ibody i- iCorrect iAnswer-
integumentary, iskeletal, imuscular, inervous,
iendocrine, icardiovascular, ilymphatic/immune,

irespiratory, idigestive, iurinary, ireproductive



integumentary isystem i- iCorrect iAnswer--skin, ihair,
inails, isweat iglands, ioil iglands

-protects ibody, iregulate ibody itemp, ieliminate isome
iwaste, imake ivitamin id, idetect isensations, istore ifat,

iprovide iinsulation



skeletal isystem i- iCorrect iAnswer--bones, ijoints,
icartilage i




iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii Vendarsol

,-support, iprotection, imovement, isurface ifor imuscle
iattachment, ihouse ithe icells ithat iproduce iblood

icells

-axial= imiddle ibody iand ihead
-appendage= ianything iattached, ipelvic igirdle

muscular isystem i- iCorrect iAnswer--skeletal imuscle
itissue

-movement, iposture, iheat iproduction

nervous isystem i- iCorrect iAnswer--brain, ispinal
icord, inerves, ieyes, iears

-rapid icommunication
-wired isystem= ifaster ithan iendocrine
-begins iin ibrain ithen ito ispinal icord
-generates iaction ipotentials, inerve iimpulses,
idetects, iinterprets, iresponds iand iregulates

ichanges iin ithe ibody i(homeostasis)



endocrine isystem i- iCorrect iAnswer--hormone
iproducing iglands

-all iglands i(pineal, ihypothalamus, ipituitary,
ithymus, ithyroid, iparathyroid, iadrenal, ipancreas,

iovaries, itestes)

-regulate iactivity/homeostasis iby ireleasing
ihormones

-wireless isystem= islower ithan inervous
-gland iof iorigin isecretes ihormones iinto
ibloodstream, itravels iuntil ireaches iproper

ireceptors...not idirect



cardiovascular isystem i- iCorrect iAnswer--blood,
iheart, iblood ivessels i




iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii Vendarsol

, -heart ipumps iblood ithru iblood ivessels, iblood
icarries ioxygen iand inutrients ito icells, icarries

icarbon idioxide iand iwaste iaway ifrom icells, iregulate

-blood icontents= idefend iagainst idisease, irepair
idamaged iblood ivessels

-takes iwaste ito ilungs
-two isided ipump i(systemically iand ipulmonically)

lymphatic/immune isystem i- iCorrect iAnswer--lymph,
ivessels, ispleen, ithymus, ilymph inodes, itonsils, iB

iand iT icells i(carry iimmune iresponse)

-carry iimmune iresponses, ireturn iprotein/fluid ito
iblood, icarry ilipids ifrom iGI itract ito iblood, icontain

isite iof iB iand iT icells ithat idefend iagainst imicrobes



respiratory isystem i- iCorrect iAnswer--lungs,
ipharynx, ilarynx, itrachea, ibronchial itubes

-air ipassageway, itransfer ioxygen ifrom iair ito iblood,
itransfer icarbon idioxide ifrom iblood ito iexhale

-acid/base ibalance iof ifluids
-air iflowing iout iof ilungs ithru ivocal icords imakes
isound



digestive isystem i- iCorrect iAnswer--intestines, iliver,
igalbladder, ipancreas, iGI iorgans, imouth, ipharynx,

iesophagus, ianus, isalivary iglands

-begins iin imouth
-breakdown, iabsorption, isecretion iof inutrients
i(carbs, ifats, iproteins)

-alimentary icanal= ithe iwhole ipassage ialong iwhich
ifood ipasses ithru ithe ibody ifrom imouth ito ianus
