Qhov Tseem Ceeb - Pulmonary Artery vs Pulmonary Vein
Ua ntej sib tham txog qhov nruab nrab ntawm Pulmonary Artery thiab Pulmonary Vein kom meej, cia peb tham luv luv ua ntej tham txog cov hlab ntshav thiab nws txoj haujlwm. Cov tib neeg cov hlab ntsha yog kaw kaw thiab feem ntau muaj lub plawv; lub twj tso kua mis muaj zog, thiab ntau cov hlab ntsha, uas thauj cov ntshav thoob plaws hauv lub cev. Cov kab ke no ua lub luag haujlwm xa cov pa oxygen thiab lwm yam khoom noj tseem ceeb rau lub cev lub hlwb thiab tshem tawm cov khoom siv hluav taws xob los ntawm cov hlwb. Tsis tas li ntawd, lub circulatory system kuj muaj feem xyuam rau lub cev tiv thaiv kab mob. Ob txoj hlab ntshav muaj nyob hauv tib neeg lub cev, uas yog; pulmonary system thiab pulmonary system. Pulmonary circulation yog cov kev ncig uas tshwm sim hauv lub ntsws thiab lub luag haujlwm rau kev sib pauv roj ntawm cov ntshav thiab alveoli ntawm lub ntsws. Pulmonary arteries thiab pulmonary veins yog cov khoom tseem ceeb ntawm pulmonary circulatory system. Cov kab mob hauv lub cev suav nrog tag nrho cov hlab ntsha thiab cov hlab ntsha uas pom hauv thiab sab nraud ntawm lub cev, tshwj tsis yog lub ntsws. Qhov sib txawv tseem ceeb ntawm ob qho no yog Pulmonary artery thauj cov ntshav deoxygenated los ntawm txoj cai ventricle ntawm lub plawv mus rau lub ntsws thaum Pulmonary veins xa cov ntshav oxygenated los ntawm lub ntsws mus rau sab laug atrium.
Pulmonary Artery yog dab tsi?
Pulmonary artery thauj cov ntshav deoxygenated los ntawm txoj cai ventricle ntawm lub plawv mus rau lub ntsws. Lub semilunar valve thaum pib ntawm cov hlab ntsha pulmonary tiv thaiv cov ntshav rov qab mus rau hauv lub plawv. Cov hlab ntsha pulmonary yog tib cov hlab ntsha uas nqa cov ntshav tsis muaj oxygen uas tsis yog cov hlab ntsha hauv plab hauv plab. Cov hlab ntsha no luv thiab dav (txog 5 cm ntev thiab 3 cm nyob rau hauv lub cheeb) thiab ceg mus rau hauv ob lub ntsws hlab ntsha, ob leeg xa ntshav mus rau sab xis thiab sab laug ntsws. Cov ntshav nqa los ntawm cov hlab ntsha pulmonary muaj ntau cov khoom pov tseg thiab cov pa roj carbon dioxide siab, uas yog sib pauv thiab tawm ntawm lub ntsws.
Pulmonary Vein yog dab tsi?
Pulmonary veins xa cov ntshav oxygenated los ntawm lub ntsws mus rau sab laug atrium. Nws yog tib leeg leeg uas nqa cov ntshav oxygenated mus rau lub plawv. Tib neeg muaj plaub lub hlab ntsha pulmonary, ob leeg ntawm txhua lub ntsws. Pulmonary veins nqa ntshav los ntawm lub ntsws sab xis yog hu ua txoj cai superior thiab sab xis inferior veins thaum lwm ob leeg pulmonary leeg yog hu ua sab laug superior thiab sab laug inferior leeg. Pulmonary veins ceg mus rau hauv cov hlab ntsha me me ua lub network ntawm capillaries hauv alveoli, qhov chaw pauv roj.
Qhov txawv ntawm Pulmonary Artery thiab Pulmonary Vein yog dab tsi?
Kev txhais ntawm Pulmonary Artery thiab Pulmonary Vein
Pulmonary artery: Pulmonary artery yog cov hlab ntsha uas nqa cov ntshav deoxygenated los ntawm txoj cai ventricle ntawm lub plawv mus rau lub ntsws
Pulmonary veins: Pulmonary vein yog cov hlab ntsha uas nqa cov ntshav oxygenated los ntawm lub ntsws mus rau sab laug atrium.
Tus yam ntxwv ntawm Pulmonary Artery thiab Pulmonary Vein
Xwm Txheej Ntshav
Pulmonary artery: Pulmonary artery nqa cov ntshav deoxygenated nrog ntau cov metabolism hauv khib nyiab thiab siab carbon dioxide concentration
Pulmonary veins: Pulmonary vein nqa cov ntshav oxygenated nrog oxygen ntau dua thiab tsis muaj cov metabolism hauv cov khib nyiab
Anatomy
Pulmonary artery: Pulmonary artery txuas nrog txoj cai ventricle ntawm lub plawv
Pulmonary veins: Pulmonary vein txuas rau sab laug atrium ntawm lub plawv
Nruas
Pulmonary artery: Pulmonary vein ceg ua ob.
Pulmonary veins: Txhua lub ntsws muaj ob txoj hlab ntsws pulmonary, yog li plaub leeg pulmonary tag nrho.
Ib lub semilunar valve tsuas yog tshwm sim thaum pib ntawm cov hlab ntsha pulmonary.
