Koj cov leeg plawv xav tau nws cov ntshav txaus vim, zoo li koj lub cev, nws xav tau oxygen thiab lwm yam khoom noj kom noj qab haus huv. Vim li no, koj lub siab pumps oxygen-nplua nuj ntshav rau nws tus kheej cov leeglos ntawm koj cov hlab ntsha coronary. Ua kom cov ntshav ntws tau zoo.
Lub plawv oxygenate ntshav li cas?
Ntshav nkag mus rau sab xis atrium thiab dhau los ntawm txoj cai ventricle. Lub ventricle txoj cai tso cov ntshav mus rau lub ntsws qhov uas nws ua oxygenated. Cov ntshav oxygenated yog coj rov qab mus rau lub plawv los ntawm cov hlab ntsha pulmonary uas nkag mus rau sab laug atrium. Los ntawm sab laug atrium ntshav ntws mus rau sab laug ventricle.
Puas lub plawv puas muaj cov ntshav oxygen?
Lub luag haujlwm ntawm lub plawv yog txhawm rau tso cov ntshav oxygenated nyob ib puag ncig lub cev, thiab xa cov ntshav deoxygenated thiab cov khoom pov tseg (carbon dioxide) mus rau lub ntsws. Lub plawv muaj plaub chav, txhua qhov sib cais los ntawm cov li qub uas tsuas tso cai rau cov ntshav ntws mus rau hauv ib qho kev coj.
Vim li cas cov hlab ntsha nqa oxygenated ntshav?
Cov hlab ntsha feem ntau nqa cov ntshav oxygenated xa oxygen mus rau hauv nruab nrog cev, thiab cov hlab ntsha feem ntau nqa cov ntshav deoxygenated rov qab mus rau lub plawv kom rov ua pa. Cov lus tshwj xeeb yog cov hlab ntsha pulmonary thiab pulmonary leeg.
Vim li cas thiaj yuav tsum tau cov ntshav ntws mus rau hauv peb lub cev?
Cov ntshav uas xav tau oxygen (xws li cov ntshav deoxygenated) yog xa mus rau koj lub ntsws kom khawsoxygen thiab tshem tawm cov pa roj carbon dioxide. Koj lub plawv dhia txhua hnub kom cov ntshav ncig lub cev. Qhov nruab nrab, cov ntshav liab hauv cov hlab ntshav yuav dhau los ntawm lub plawv txhua 45 vib nas this.
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.
Cov ntshav deoxygenated ua oxygenated li cas?
Ntshav nkag mus rau sab xis atrium thiab dhau los ntawm txoj cai ventricle. Lub ventricle txoj cai tso lub ntshav mus rau lub ntswsqhov twg nws dhau los ua oxygenated. Cov ntshav oxygenated tau coj rov qab mus rau lub plawv los ntawm cov hlab ntsha pulmonary uas nkag mus rau sab laug atrium.
Vim li cas mob qog noj ntshav tsis cuam tshuam lub plawv?
Lub plawv, qhov sib piv, tsis raug ntau cov carcinogens, tsuas yog cov hauv cov ntshav xwb. Qhov ntawd, ua ke nrog qhov tseeb tias lub plawv hlwb tsis feem ntau rov ua dua, yog vim li cas koj tsis pom ntau mob qog noj ntshav ntawm lub plawv.
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?
Vim li cas plawv plawv thiaj tseem ceeb?
Kev ua haujlwm siab ua kom koj lub siab, lub ntsws thiab cov hlab ntshav kom noj qab haus huv thiab txhim kho koj lub cev tag nrho. Yog li ntawd, cov neeg uas tau txais kev pom zoo ua lub cev tsis tu ncua tuaj yeem txo qhov kev pheej hmoo ntawm ntau yam kab mob xws li ntshav qab zib, kab mob plawv thiab mob stroke.
