Ib yam li lwm cov molluscs, cov circulatory system ntawm gastropods yog qhib, nrog cov kua dej, los yog haemolymph, ntws los ntawm sinuses thiab da dej cov ntaub so ntswg ncaj qha. Lub haemolymph feem ntau muaj haemocyanin, thiab yog xim xiav.
Tsis tas li ntawd, hom kab mob dab tsi ua rau gastropods thiab bivalves muaj?
Feem ntau mollusks muaj ib qhib circulatory system tab sis cephalopods (squids, octopus) muaj ib kaw circulatory system . Cov ntshav ntshav ntawm mollusks yog hemocyanin, tsis yog hemoglobin. Lub plawv ntawm clam tuaj yeem pom hauv daim duab hauv qab no. Bivalves muaj peb khub ganglia tab sis ua tsis muaj ib lub hlwb.
Ib yam li ntawd, cov slugs puas muaj cov hlab ntsha? Cov circulatory systems hauv a slug thiab hauv qwj yog zoo heev. Ob leeg muaj qhib circulatory systems . Cov slug lub circulatory system thauj cov kua dej hu ua hemolymph. Hemolymph zoo ib yam li cov kua dej hauv lub cev qwj vim nws tsim cov ntshav, dej, rog, thiab cov proteins uas tseem ceeb rau lub cev. slug nyob.
Ntxiv mus, hom kab mob hauv lub cev ua mollusks muaj dab tsi?
Txhua mollusks tshwj tsis yog cov nyob hauv chav kawm Cephalopoda muaj qhib circulatory system . Hauv qhov qhib circulatory system , ntshav tsis muaj nyob rau hauv cov hlab ntsha. Lub plawv tso ntshav los ntawm cov hlab ntsha uas coj los ntawm gills mus rau hauv lub cev kab noj hniav hu ua hemocoels.
Cov piv txwv ntawm gastropods yog dab tsi?
A gastropod yeej yog ib hom tsiaj uas nyob hauv chav hu ua Gastropoda . Qwj, slugs, thiab nudibranchs, lossis tsiaj txhu zoo li cov dej ntsev, yog txhua yam piv txwv ntawm gastropods.

Cov hlab ntsha twg tuaj yeem khaws cov qog ntshav los ntawm lub hauv siab thiab hauv qab hauv lub cev?
Cev thoracic
Cov hlab ntsha hlab ntsha thiab cov hlab ntshav muaj dab tsi?
Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg
Puas yog Neuroglia tsim cov hlab ntsha hauv cov hlab ntsha hauv nruab nrab cov hlab ntsha?
Muaj plaub hom neuroglia pom nyob hauv nruab nrab lub paj hlwb: Astrocytes - tswj cov ntshav lub hlwb teeb meem thiab khaws cov tshuaj ib puag ncig los ntawm kev siv cov ions rov qab thiab cov tshuaj xa xov mus rau lub cev. Oligodendrocytes - myelinate axons nyob rau hauv lub hauv nruab nrab lub paj hlwb thiab muab tag nrho cov txheej txheem txheej txheem
Vim li cas peb thiaj sau cov ntshav los ntawm cov hlab ntsha thiab tsis yog los ntawm cov hlab ntsha?
Cov leeg yuav tsum tau li qub kom cov ntshav ntws mus rau lub plawv. Theses li qub yog qhov tshwj xeeb hauv ob txhais ceg thiab caj npab. Lawv tawm tsam lub ntiajteb txawj nqus los tiv thaiv cov ntshav rov qab los. Cov hlab ntsha tsis xav tau li qub vim tias lub siab los ntawm lub plawv ua kom cov ntshav ntws los ntawm lawv mus rau ib qho
Cov hlab ntsha hauv lub ntsws txawv li cas ntawm cov hlab ntsha hauv nruab nrog cev?
Cov hlab ntsha. Cov hlab ntsha hauv lub ntsws nqa cov ntshav oxygen tsawg los ntawm txoj hlab ntshav ntawm lub plawv mus rau lub ntsws. Cov hlab ntsha hauv lub cev thauj cov ntshav oxygenated los ntawm sab laug ventricle ntawm lub plawv mus rau tag nrho lub cev. Cov leeg
