Cov circulatory system yog tsim los ntawm cov hlab ntshav uas nqa ntshav tawm ntawm thiab mus rau lub plawv. Cov circulatory system nqa cov pa oxygen, cov as -ham, thiab cov tshuaj hormones rau cov cell, thiab tshem tawm cov khoom pov tseg, xws li cov pa roj carbon dioxide. Cov kev no taug kev hauv ib qho kev taw qhia nkaus xwb, txhawm rau ua kom cov khoom mus rau qhov lawv yuav tsum tau ua.
Nyob rau hauv no txoj kev, dab tsi yog lub luag hauj lwm rau circulatory system?
Cov circulatory system , kuj hu ua cov hlab plawv los yog lub cev lawv , yog lub cev lawv uas tso cai rau cov ntshav mus ncig thiab thauj cov as -ham (xws li cov amino acids thiab electrolytes), oxygen, carbon dioxide, cov tshuaj hormones, thiab cov qe ntshav mus thiab los ntawm cov cell hauv lub cev los muab kev txhawb nqa thiab pab hauv
Ib yam nkaus, cov kabmob hauv lub cev ua haujlwm rau menyuam yaus yog dab tsi? Lub circulatory system yog tsim los ntawm plawv thiab cov hlab ntsha , nrog rau cov hlab ntsha, leeg , thiab capillaries.
Tom qab ntawd, ib tus kuj tseem yuav nug, vim li cas txoj kev ncig ntshav tseem ceeb rau menyuam?
Lub cev circulatory system yog lub luag haujlwm thauj cov khoom siv thoob plaws lub cev. Nws xa cov as -ham, dej, thiab oxygen rau koj ntau txhiab lub cev ntawm lub cev thiab nqa cov khoom pov tseg xws li carbon dioxide uas lub cev tsim tawm.
Yuav ua li cas cov ntshav ncig ua haujlwm ib kauj ruam zuj zus?
Ntshav ntws los ntawm koj lub plawv thiab lub ntsws hauv plaub cov kauj ruam : Txoj cai atrium tau txais cov ntshav tsis muaj oxygen los ntawm lub cev thiab tso nws mus rau sab xis ventricle los ntawm tricuspid valve. Txoj hlab ntshav sab xis tso cov ntshav tsis zoo oxygen mus rau lub ntsws los ntawm lub ntsws.

Yuav ua li cas yog lub circulatory system nyob rau hauv vertebrate?
Cov kab ke ncig ua haujlwm muaj txiaj ntsig zoo ntawm cov hlab ntsha cylindrical: cov hlab ntsha, cov leeg, thiab cov hlab ntsha uas tawm los ntawm lub twj tso kua mis, lub plawv. Nyob rau hauv tag nrho cov kab mob vertebrates, nrog rau ib co invertebrates, qhov no yog ib tug kaw-voj system, uas cov ntshav tsis pub dawb nyob rau hauv ib tug kab noj hniav
Vim li cas lub circulatory system xav tau lub tshuab ua pa?
Lub hauv paus ntshav muaj txiaj ntsig zoo. Cov txheej txheem no thauj cov khoom noj khoom haus, thiab oxygen mus rau lub cev hlwb. Nws tseem xa cov pa roj carbon dioxide thiab cov khoom pov tseg. Qhov no pab txoj kev ua pa los ntawm kev thauj cov as -ham kom lub ntsws huv, thiab noj qab nyob zoo
Lub cev twg yog lub luag haujlwm rau propulsion ntawm cov zaub mov ntawm lub qhov ncauj mus rau lub plab?
Esophagus Hauv qhov no, kev tawm dag zog lub cev zom zaub mov yog dab tsi? Ingestion yog txheej txheem ntawm noj. Kev tawm tsam yog kev txav ntawm cov zaub mov raws li digestive ib ntsuj av . Qhov loj txhais tau tias ntawm kev tawm tsam yog peristalsis, ua ntu ntu ntawm kev sib txuam sib cog lus thiab so ntawm cov leeg du uas ua kab ntawm phab ntsa ntawm plab zom mov lub cev thiab uas yuam cov zaub mov txav mus tom ntej.
Yuav ua li cas yog nyob rau hauv lub circulatory system?
Cov kab ke ncig ua haujlwm yog ua los ntawm cov hlab ntshav uas nqa ntshav tawm ntawm thiab mus rau lub plawv. Cov hlab ntsha nqa ntshav tawm ntawm lub plawv thiab cov hlab ntsha nqa ntshav rov qab mus rau lub plawv. Lub cev ncig ua haujlwm nqa cov pa oxygen, cov as -ham, thiab cov tshuaj hormones rau cov cell, thiab tshem tawm cov khoom pov tseg, xws li carbon dioxide
Dab tsi yog qhov ua haujlwm ntawm lub teeb pom kev ntawm cov menyuam yaus?
Cov menyuam kawm ntawv lub teeb pom kev zoo (PLR) lossis cov duab thaij duab yog qhov ua kom pom zoo uas tswj lub taub ntawm cov tub ntxhais kawm, hauv kev teb rau qhov siv zog (luminance) ntawm lub teeb uas poob rau ntawm cov hlab ntshav ntawm cov hlab ntshav retina nyob tom qab ntawm lub qhov muag, yog li pab hauv kev hloov kho qhov muag mus rau ntau qib ntawm qhov pom kev
