cov hlab ntsha: Cov ntshav txav mus los ntawm ntau lub raj hu ua arteries thiab cov leeg, uas ua ke hu ua cov hlab ntsha. Cov hlab ntsha uas nqa ntshav tawm ntawm lub plawv yog hu ua cov hlab ntsha. Cov uas nqa ntshav rov qab mus rau lub plawv yog hu ua veins.
Yuav ua li cas ntshav rov qab rau lub siab?
Cov leeg (xiav) coj cov ntshav tsis muaj oxygen rov qab mus rau lub plawv. Cov hlab ntsha pib nrog lub aorta, cov hlab ntsha loj tawm hauv plawv. Lawv nqa cov ntshav uas muaj oxygen tawm ntawm lub plawv mus rau tag nrho lub cev nqaij daim tawv.
peb hu li cas cov hlab uas nqa ntshav mus rau lub plawv?
cov hlab ntsha: Cov ntshav txav mus los ntawm ntau lub raj hu ua arteries thiab cov leeg, uas ua ke hu ua cov hlab ntsha. Cov hlab ntsha uas nqa ntshav tawm ntawm lub plawv yog hu ua cov hlab ntsha. Cov uas nqa ntshav rov qab mus rau lub plawv yog hu ua veins.
Vim li cas thiaj yuav tsum tau cov ntshav ntws mus rau hauv peb lub cev?
Koj lub siab yog lub zog nqus cov leeg uas ua haujlwm tsis tu ncua kom koj lub cev tau txais oxygen nplua nuj ntshav. Cov teeb liab los ntawm lub plawv hluav taws xob teeb tsa qhov nrawm thiab qauv ntawm lub twj tso kua mis lub suab.
Cov hlab ntsha loj tshaj plaws hauv koj lub cev nyob qhov twg?
Cov hlab ntsha loj tshaj plaws hauv tib neeg lub cev yog qhov tsis zoo vena cava, uas nqa cov ntshav deoxygenated los ntawm ib nrab ntawm lub cev rov qab mus rau lub plawv.

Leej twg cov hlab ntsha nqa cov ntshav oxygenated?
Cov hlab ntsha nqa cov ntshav oxygenated los ntawm lub plawv , thaum cov hlab ntsha nqa cov ntshav uas tsis muaj oxygen rov qab mus rau lub plawv. Ib qho yooj yim mnemonic yog "A rau 'artery' thiab 'tawm' (los ntawm lub plawv). (Cov kev zam rau txoj cai dav dav no yog cov hlab ntsws pulmonary hlab ntsha pulmonary ncig pumps deoxygenated ntshav los ntawm pulmonary artery.
Cov hlab ntsha twg nqa ntshav mus rau lub plawv?
Muaj peb hom hlab ntsha Cov hlab ntsha (liab) nqa oxygen thiab cov as-ham tawm ntawm koj lub siab, mus rau koj lub cev cov ntaub so ntswg. Lub veins (xiav) coj cov ntshav tsis muaj oxygen rov qab mus rau lub plawv. Cov hlab ntsha pib nrog lub aorta, cov hlab ntsha loj tawm hauv plawv .
Thaum twg tus mob ntshav qab zib tau hloov mus rau ntshav qab zib?
Yog tias koj muaj ntshav qab zib, koj cov ntshav qabzib yuav nce mus rau 100 mg / dL txog 125 mg / dL. Thaum koj cov ntshav qabzib nce siab dua 125, koj yuav raug kuaj mob ntshav qab zib . Yuav siv sijhawm ntev npaum li cas rau cov ntshav qab zib kom hloov mus ua ntshav qab zib?
Qhov twg yog qhov chaw uas cov kua qaub ncaug rov qab mus rau cov ntshav?
Lim cov kua dej lim dej ces txav mus rau qhov loj lymphatic ducts lymphatic ducts Ib lub qog ntshav yog lub lymphatic hlab ntsha loj uas tso cov qog ntshav mus rau hauv ib qho ntawm cov hlab ntsha subclavianMuaj ob lub qog ntshav hauv lub cev - txoj cai lymphatic duct thiab lub thoracic duct.
Cov hlab me me tshaj plaws nyob rau hauv cov hlab ntsha hu ua qhov twg?
Cov hlab ntsha me tshaj plaws, hu ua capillaries, me me heev koj xav tau lub tshuab ntsuas kom pom lawv. Capillaries koom ua cov hlab ntsha loj. Qhov loj dua yog hu ua cov leeg. Cov hlab no nqa ntshav rov qab mus rau lub plawv . Cov hlab ntsha me tshaj plaws lossis cov hlab ntsha hauv cov hlab ntsha yog dab tsi?
