Cov kab mob plawv yog qee zaum hu ua ntshav-vascular, lossis tsuas yog cov hlab ntshav, system. Nws muaj lub plawv, uas yog cov khoom siv lub cev, thiab lub kaw lus kaw ntawm cov hlab ntsha hu ua cov hlab ntsha, cov hlab ntsha, thiab cov hlab ntsha.
Qhov txawv ntawm lub plawv thiab hlab ntsha?
Los ntawm lub siab ua haujlwm, mus rau peb cov hlab ntsha tuab tshaj plaws, mus rau cov hlab ntshanyias nyias tias lawv tsuas pom tau los ntawm lub tshuab tsom iav xwb, cov hlab plawv yog peb lub cev txoj sia. Lub circulatory system yog tsim los ntawm lub plawv thiab cov hlab ntsha, nrog rau cov hlab ntsha, hlab ntsha, thiab capillaries.
Lub plawv thiab hlab plawv ua haujlwm ua ke li cas?
Lub plawv thiab cov hlab ntsha ua rau koj lub plawv dhia. Koj lub plawv ua haujlwm ua lub twj tso kua mis uas thawb cov ntshav mus rau hauv nruab nrog cev, cov ntaub so ntswg, thiab cov hlwb ntawm koj lub cev. Ntshav xa cov pa oxygen thiab cov as-ham rau txhua lub cell thiab tshem tawm cov pa roj carbon dioxide thiab cov khoom pov tseg uas tsim los ntawm cov hlwb.
3 hom kab mob ntshav qab zib yog dab tsi?
3 Yam Kev Tshaj Tawm:
- Systemic ncig.
- Pulmonary ncig.
Lub circulatory system Thauj yog dab tsi?
Lub circulatory system xa oxygen thiab as-ham rau hlwb thiab tshem tawm cov khib nyiab. Lub plawv twj tso kua mis oxygenated thiab deoxygenated ntshav ntawm txawvsab. Cov hlab ntsha muaj xws li cov hlab ntsha, capillaries thiab cov hlab ntsha.
Pom zoo:
Lub plawv lub plawv twg tau txais cov ntshav oxygenated?
Ntshav nkag mus rau txoj cai atrium thiab hla txoj cai ventricle. Txoj cai ventricle tso cov ntshav mus rau lub ntsws uas nws ua oxygenated. Cov ntshav oxygenated yog coj rov qab mus rau lub plawv los ntawm pulmonary veins pulmonary veins Lub pulmonary veins yog cov hlab ntsha uas xa cov ntshav oxygenated los ntawm lub ntsws mus rau lub plawv.
Puas yog qhov zoo thiab zoo nkauj yog cov ntaub ntawv kawm zoo?
Qhov no yog ib qho kev kawm pheej yig heev thiab pheej yig dua me ntsis ntau dua li cov ntaub ntawv kawm hauv tsev. Lub Hom Phiaj Zoo thiab Zoo Nkauj yog txhawm rau ntxiv dag zog rau menyuam yaus thiab tsev neeg, yog vim li cas lawv khaws lawv cov txiaj ntsig qis.
Lub sijhawm twg yog lub plawv lub plawv muaj ntshav?
Lub sijhawm ntawm kev cog lus uas lub plawv dhia thaum nws tso cov ntshav mus rau hauv cov hlab ntsha hu ua systole. Lub sijhawm so uas tshwm sim thaum cov chav ntim ntshav yog hu ua diastole. Nyob rau theem twg ntawm lub plawv dhia yog lub plawv muaj ntshav?
Puas yog cov hlab ntsha loj dua cov hlab ntsha?
Arterioles nqa ntshav thiab oxygen mus rau hauv cov hlab ntsha me tshaj plaws, cov hlab ntsha. Capillaries yog li ntawd small lawv tsuas pom tau nyob hauv lub tshuab tsom. Cov phab ntsa ntawm capillaries yog permeable rau oxygen thiab carbon dioxide.
Puas yog cov hlab ntsha tawv tawv yog mob plawv?
Cov quav hniav tuaj yeem ua rau koj cov hlab ntsha nqaim, thaiv cov ntshav ntws. Cov quav hniav kuj tuaj yeem tawg, ua rau cov ntshav txhaws. Txawm hais tias atherosclerosis feem ntau suav tias yog teeb meem plawv, nws tuaj yeem cuam tshuam cov hlab ntsha nyob txhua qhov chaw hauv koj lub cev.
