Squids , zoo li tib neeg, muaj a kaw circulatory system , txhais tau hais tias tag nrho lawv cov ntshav muaj nyob rau hauv cov hlab ntsha (cov hlab ntsha, hlab ntsha, thiab capillaries). Lub plawv brachial tso cov ntshav deoxygenated rov qab mus rau cov gills kom cov pa roj carbon dioxide tuaj yeem raug tshem tawm thiab oxygen absorbed los ntawm cov dej nyob ib puag ncig.
Ib yam li ntawd, nws raug nug, vim li cas squid muaj lub kaw lus kaw?
Squids thiab octopi yog qhov piv txwv tseem ceeb ntawm cephalopods. Lawv muaj qhov kaw cov hlab ntshav yog li lawv tuaj yeem txav nrawm dua - lub kaw circulatory system tso cai ntau npaum "pinpointing" ntawm ntshav . Squid kuj muaj cov hlab ntsha loj tshaj plaws hauv lub nceeg vaj tsiaj. Qhov no ua rau lawv txav tau sai heev.
Ib sab saum toj no, cephalopods puas muaj qhov qhib lossis kaw cov hlab ntshav? Cov cephalopod pab pawg suav nrog octopuses nyob, squid, cuttlefish, thiab nautiloids. Tsis zoo li tag nrho lwm cov mollusks, cephalopods muaj a kaw circulatory system . Qhov no txhais tau tias cov ntshav ntws los ntawm cov hlab ntsha rov qab los rau hauv lub plawv, tsis yog da dej nruab nrog cev hauv cov ntshav zoo li hauv qhib circulatory systems.
Ua kom pom qhov no, cov kab mob puas tau qhib lossis kaw cov hlab ntsha?
Clams muaj ib qhib circulatory system ; tib neeg muaj a kaw circulatory system . Ob leeg tshuab txav cov ntshav thoob plaws lub cev muab kev sib pauv ntawm cov as -ham/oxygen rau cov khoom pov tseg/carbon dioxide, ntawm qib cellular.
Dab tsi yog qhov kom zoo dua ntawm qhov kaw cov hlab ntshav kaw?
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.

Nyob rau theem twg ntawm viral lub neej voj voog yuav tus kab mob tau txais nws lub hnab ntawv?
Nrog cov kab mob hauv lub hnab ntawv, tus tswv tsev yuav yog lossis tsis tuaj yeem lysed. Cov kab mob tau txais lawv lub hnab ntawv los ntawm tus tswv tsev cell daim nyias nyias los ntawm kev tawg paj. Raws li tau hais los saud, ua ntej yuav tawg paj, cov kab mob kis tau thiab cov glycoproteins tau muab tso rau hauv tus tswv tsev lub cell daim nyias nyias
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
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
Puas yog tib neeg muaj lub kaw lus kaw lub cev?
Tib neeg tau kaw cov hlab ntsha. Qhov no txhais tau tias cov ntshav ib txwm nyob hauv cov hlab ntsha thiab lub plawv thaum ncig thoob plaws lub cev. Taug kev hla cov hlab ntsha thiab cov leeg, cov ntshav nqa cov molecules tseem ceeb thoob plaws hauv lub cev thiab ib txwm raug kaw
