Qhov twg muaj teeb meem tshuaj raug cab coj mus los ntawm cov ntshav? Cov kev tiv thaiv nuj nqi ntawm cov kua cev cov ntaub so ntswg

Cov hlab ntsha nrog ib tug thauj system ntawm lub cev. Txhua thib ob, nws yog ib tug ntau yam ntawm lub tebchaw, ib co kev uas yog tshuaj lom. Qhov twg muaj teeb meem tshuaj raug cab coj mus los ntawm cov ntshav, thiab yog dab tsi dab muab qhov chaw nrog lawv nyob rau hauv lub cev?

Cov kev tiv thaiv nuj nqi ntawm cov ntshav

Ntau tebchaw thiab kab mob nkag mus rau hauv lub internal puag ncig los ntawm cov pa thiab digestive systems, uas ua rau tig nyob rau hauv cov hlab ntsha. Muaj ntau ntawm lawv muaj peev xwm ua rau muaj mob loj thiab ua rau txaus ntshai kab mob.

Qhov twg entrained ntshav ntawm teeb meem tshuaj? Lawv yuav ntsib nrog cov kev txiav txim ntawm leukocytes. Cov kev tiv thaiv hlwb nqus thiab ces nqis tag nrho cov txawv teb chaws cov nqaijrog, cov kab mob thiab kab mob. Qhov no yog hu ua phagocytosis, los yog intracellular digestion. Nyob rau hauv ua li ntawd, cov qe ntshav dawb tuag thiab sawv daws yuav tshiab yog tsim nyob rau hauv lub qog thiab thymus.

Qhov twg muaj teeb meem tshuaj raug cab coj mus los ntawm cov ntshav?

Ua ke nrog cov zaub mov thiab cov huab cua sab hauv lub cev thiab yog ib tug ntau yam ntawm toxins. Qhov twg muaj teeb meem tshuaj raug cab coj mus los ntawm cov ntshav? Ua ntej ntawm tag nrho cov, lawv kis tau los ntawm ib tug thiaj li hu ua barrier kabmob. Xav txog cov mechanism ntawm lawv txiav txim rau cov piv txwv ntawm lub siab.

Nws yog cov coob digestive caj pas, uas tau txais cov ntshav los ntawm cov leeg ntawm lub plab thiab cov hnyuv. Ntawm no yog lim tawm ntawm nws pab tau tebchaw thiab toxins yog neutralized. Ua ke nrog cov kua tsib, lawv yog tso zis rau sab nraum. Lub siab kuj tshwm sim phagocytic kev puas tsuaj puas lawm erythrocytes. Feem ntawm cov teeb meem thiab pliaj yam tshwm sim los ntawm lub digestive kabmob, ua pa, mob txeeb thiab daim tawv nqaij. Lub ntsiab pauv cov khoom xws li carbon dioxide, urea, ntsev ntawm hnyav hlau.

Cov zaub mov muaj nuj nqi ntawm cov ntshav

Tam sim no cia saib, qhov twg raug cab coj mus los ntawm cov ntshav ntawm cov as-ham uas puas lawm. Cov nqaijrog, lipids thiab carbohydrates yog biopolymers. Qhov no txhais tau tias lawv muaj xws li ib tug xov tooj ntawm repeating units. Nyob rau hauv cov hnyuv cov proteins decompose rau hauv amino acids, polysaccharides - nyob rau hauv tej yam yooj yim carbohydrates, thiab nqaijrog - glycerin thiab lub siab carboxylic acid.

Yog li ib qhov nqi ntawm lub zog yog tso tawm uas yog siv los mus siv rau cov kab mob neej dab. Yog vim li cas yog kev puas tsuaj ntawm biopolymers? Qhov no yog hais tias lawv molecules yog heev loj. Yog li ntawd, lawv muaj peev xwm tsis txeem los ntawm cov hnyuv mus rau hauv cov hlab ntsha. Lub monomers kuj ua li no yooj yim. Txij li thaum cov ntshav tam sim no yog pub rau lub hlwb thiab kabmob uas dua yog lawv "tuaj txoos ua ke" tsim tau ib cov complex organic tshuaj.

Yuav ua raws li nkev pauv

Gas pauv kuj yog ib tug yuavtsum tau kawm uantej rau tej lub cev tau hauj lwm. lub caj pas, oxygen nkag mus rau hauv lub ntsws, uas muaj ib tug loj tus naj npawb ntawm cov me me npuas - lub alveoli. Lub luag hauj lwm ntawm cov me lug yog enormous. Nws yog nyob rau hauv lub alveoli nkev pauv tshwm sim nruab nrab ntawm cov pa thiab lub plawv systems.

Lawv ua hauj lwm yog ib txwm ua ua ke. Nrog rau oxygen, oxidation ntawm cov organic tshuaj, uas ua nyob rau hauv tsim carbon dioxide. Qhov no tshuaj ntaub ntawv ib tug tsis ruaj tsis khov compound nrog hemoglobin. Qhov twg yog nqa nyob rau hauv cov ntshav carbon dioxide thiab dej vapor? Ntawm cov hoob kawm, rov qab mus rau lub ntsws, ces tshuab pa, lawv raug muab tshem tawm los ntawm lub cev.

Yog li ntawd, nyob rau hauv qhov tsab xov xwm peb sib tham, uas nqa tam sim ntawd tus cov ntshav ntawm teeb meem tshuaj. Nyob rau hauv lub cev, lawv mus los ntawm ob peb thiaj li hu ua kab kws muaj txuj ci. Cov no yog cov ntshav thiab lymph, mob huam, siab, ob lub raum, daim tawv nqaij thiab lub ntsws. Part neutralized kuab paug nyob rau ntawd, thiab tus so los nrog xaiv lub cev. Los ntawm tus txheej txheem no nws yog khaws cia tas li nrog ib puag ncig thiab tiv thaiv cov kev ua ntawm cov ntshav yog ua.
