Hauv vascular nroj tsuag , raj thauj zaub mov thiab dej. Qee cov invertebrates vam khom ib kaw kaw lus ntawm lub cev, thaum lwm tus muaj qhov qhib qhov system . Tib neeg thiab lwm yam vertebrates siab dua muaj a kaw kaw lus ntawm kev ncig.
Hauv qhov no, cov nroj tsuag puas tuaj yeem muaj cov hlab ntshav ncig?
Vascular Cov txheej txheem ntawm Nroj tsuag Xylem thiab phloem ua rau kev thauj mus los loj lawv ntawm vascular nroj tsuag . Raws li koj tau loj dua, nws nyuaj rau thauj cov as -ham, dej, thiab suab thaj nyob ib puag ncig koj lub cev. Koj muaj ib tug circulatory system yog koj xav kom loj hlob. Ntoo thiab lwm yam vascular cov nroj tsuag muaj ib sab saum toj thiab hauv qab.
Qhov thib ob, yog dab tsi qhib kev ncig ua haujlwm? Qhib circulatory systems (hloov pauv hauv kab, mollusks thiab lwm yam invertebrates) tso ntshav rau hauv hemocoel nrog cov ntshav nthuav tawm rov qab mus rau circulatory system nruab nrab ntawm cov hlwb. Ntshav tau nqus los ntawm lub plawv mus rau hauv lub cev kab noj hniav, qhov twg cov ntaub so ntswg nyob ib puag ncig los ntawm cov ntshav.
Raws li txoj cai, cov tsiaj nyeg puas muaj qhov qhib lossis kaw cov hlab ntshav?
Cov hlab plawv lawv muaj lub plawv (cardio) thiab cov hlab ntsha xav tau rau kev thauj cov ntshav (vascular). Lub cev lawv muaj cov hlab ntsha, cov leeg thiab cov hlab ntsha. Vertebrates ( tsiaj nrog cov pob txha zoo li ntses, noog, cov tsiaj reptiles, thiab lwm yam), suav nrog feem ntau cov tsiaj txhu , tau kaw plawv tshuab.
Puas yog amphibians muaj qhib lossis kaw cov hlab ntshav?
Nrog ib qhib circulatory system , ntshav thiab cov as -ham tsis txwv rau kev txav mus los hauv cov hlab ntshav. Tom qab ntawd, muaj lub kaw circulatory system - qhov no yog hom vertebrates zoo li ntses, tsiaj txhu, thiab amphibians muaj.

Puas yog qhib lossis kaw lub qhov muag tsis zoo?
Kaw-lub kaum (lossis lub kaum-kaw) glaucoma ua rau tsawg dua 20 feem pua ntawm cov neeg mob glaucoma hauv Tebchaws Meskas. Feem ntau nws hnyav dua li qhib qhov muag glaucoma. Ob qho xwm txheej cuam tshuam nrog kev hloov pauv ntawm lub qhov muag uas tiv thaiv kom tsis txhob muaj dej txaus
Puas yog qhov endoplasmic reticulum pom nyob hauv cov nroj tsuag lossis tsiaj txhu?
Lub du endoplasmic reticulum, los yog du ER, yog ib qho organelle pom nyob rau hauv ob qho tib si tsiaj hlwb thiab cov hlwb cog. Organelle yog ib chav nyob hauv ib lub xovtooj uas muaj haujlwm tshwj xeeb. Lub luag haujlwm tseem ceeb ntawm ER du yog ua cov khoom lag luam ntawm tes zoo li cov tshuaj hormones thiab lipid
Hom hlab ntshav twg txuas cov hlab ntsha thiab cov hlab ntshav?
Hom hlab ntsha Capillaries yog feeb nyias-walled hlab ntsha uas txuas cov hlab ntsha thiab venules; Nws yog los ntawm cov capillaries uas cov as-ham thiab cov pov tseg tau pauv ntawm cov ntshav thiab cov ntaub so ntswg ntawm lub cev
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 cov hlab ntsha uas muaj oxygenated ntshav lossis cov hlab ntsha?
Cov hlab ntsha tau pom tias yog nqa cov ntshav oxygenated mus rau cov ntaub so ntswg, thaum cov leeg nqa cov ntshav deoxygenated rov qab mus rau lub plawv. Txawm li cas los xij, hauv txoj hlab ntsws, cov hlab ntsha nqa cov ntshav deoxygenated los ntawm lub plawv mus rau lub ntsws, thiab cov hlab ntshav rov qab ntshav los ntawm lub ntsws mus rau lub plawv
