Kev faib pab rau muaj txiaj ntsig cov ntshav oxygenated thiab deoxygenated ntshav. Noog kuj tseem muaj cov kev hloov pauv tshwj xeeb rau kev ya davhlau, suav nrog lub plawv loj dua rau lub cev hnyav thiab lub plawv dhia ceev. Lawv kuj muaj cov hlab ntshav ntau ntxiv hauv cov leeg tsim los xa cov pa oxygen ntawm qhov chaw siab.
Kuj paub yog, yuav ua li cas tus noog lub circulatory system ua haujlwm?
A noog lub circulatory system muaj plaub-chambered lub plawv thiab cov hlab ntsha. Nrog txhua qhov kev ntaus, lossis mob hlab ntsha tawg, ntawm lub plawv, cov ntshav ntau tau nqa mus thoob plaws hauv qub lub cev los ntawm cov hlab ntsha hu ua cov hlab ntsha. Cov ntshav rov qab mus rau lub plawv los ntawm cov hlab ntsha hu ua veins. Noog yog qhov zoo tshaj plaws ncaws pob.
Tsis tas li ntawd, dab tsi yog qhov zoo ntawm qhov kaw cov hlab ntshav? Nws muab lub zog ntau dua hauv daim ntawv ntawm kev siab. Piv rau qhib circulatory system , cov kaw circulatory system ua haujlwm nrog cov ntshav siab ntau dua, txawm hais tias nws tau hais kom ua tau zoo dua qhov xav tias nws siv cov ntshav tsawg dua rau qhov nrawm dua thiab ntau dua ntawm kev faib tawm.
Ua raws li qhov no hauv kev txiav txim siab, yog vim li cas ob lub circulatory system zoo dua?
Ob chav circulatory systems yog qhov tseem ceeb vim tias lawv ua kom ntseeg tau tias peb tau muab peb cov ntaub so ntswg thiab cov leeg ntshav puv cov pa, tsis yog sib xyaw oxygenated thiab deoxygenated ntshav. Thaum nws yuav siv sij hawm me ntsis ntau dua zog tshaj ib leeg circulatory system , qhov no lawv yog ntau ua tau zoo dua !
Cov noog puas muaj qhov qhib lossis kaw cov hlab ntshav?
Noog , muaj a kaw circulatory system , xav tias muaj tsiv ntau agilely, cia lawv mus tau zaub mov sai dua thiab tejzaum nws yuav raug tua ntawm cov kab. Daim duab 21.2. Hauv (a) kaw cov hlab ntshav , lub plawv twj ywm ntshav los ntawm cov hlab ntsha uas sib cais los ntawm cov kua dej interstitial ntawm lub cev.

Vim li cas nws tseem ceeb heev rau cov noog kom muaj lub cev ua pa tshwj xeeb?
Cov kab mob ua pa ntawm cov noog pab tswj kev sib pauv cov pa roj carbon dioxide thiab oxygen los ntawm kev siv cua tsis tu ncua thiab cov hnab cua. Lub cev ua pa ntawm avian yog lub cev sib txawv ntawm cov tsiaj txhu ua pa, ob qho tib si hauv cov qauv thiab hauv nws lub peev xwm los pauv cov pa roj kom zoo li sai tau
Lub plawv noog zoo li cas?
Cov noog, zoo li tsiaj txhu, muaj 4-chambered lub plawv (2 atria & 2 ventricles), nrog kev sib cais ntawm cov pa oxygenated thiab de-oxygenated ntshav. Txoj cai ventricle tso ntshav mus rau lub ntsws, thaum sab laug ventricle tso ntshav mus rau lwm lub cev
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 circulatory system ua haujlwm li cas rau cov menyuam yaus?
Cov kab ke ncig ua haujlwm yog ua los ntawm cov hlab ntshav uas nqa ntshav tawm ntawm thiab 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. 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
