Capillaries txuas cov hlab ntsha mus rau cov leeg. Cov hlab ntsha xa cov ntshav oxygen nplua nuj mus rau cov hlab ntsha, qhov twg qhov sib pauv ntawm cov pa thiab carbon dioxide tshwm sim. Cov capillaries tom qab ntawd xa cov ntshav pov tseg uas nplua nuj mus rau cov leeg kom thauj rov qab mus rau lub ntsws thiab lub plawv. Cov leeg nqa ntshav rov qab mus rau lub plawv.
Cov qauv ntawm cov hlab ntsha thiab cov hlab ntsha cuam tshuam li cas rau lawv txoj haujlwm?
Cov hlab ntsha ntws cov ntshav thoob plaws lub cev. Cov hlab ntsha thauj cov ntshav tawm ntawm lub plawv. Vim ntshav rov qab mus rau lub siab. Capillaries ncig lub cev hlwb thiab cov ntaub so ntswg kom xa thiab nqus oxygen, as-ham, thiab lwm yam khoom.
Puas yog cov hlab ntsha lossis cov hlab ntsha?
Capillaries yog me me, cov hlab ntsha nyias uas txuas cov hlab ntsha thiab cov leeg. Lawv cov phab ntsa nyias tso cai rau cov pa oxygen, cov as-ham, carbon dioxide thiab cov khoom pov tseg kom dhau mus thiab los ntawm cov ntaub so ntswg.
Cov hlab ntsha thiab cov hlab ntsha hu ua dab tsi?
A hlab ntsha yog lub raj uas nqa ntshav. Oxygen nplua nuj ntshav tawm sab laug ntawm lub plawv thiab nkag mus rau aorta. Lub aorta ceg mus rau hauv cov hlab ntsha, uas nws thiaj li ceg mus rau hauv me me arterioles. Arterioles nqa ntshav thiab oxygen mus rau hauv cov hlab ntsha me tshaj plaws, cov hlab ntsha.
Capillaries cuam tshuam nrog cov hlab ntsha li cas?
Cov alveoli yog ib puag ncig los ntawm cov ntshav me mecov hlab ntsha, hu ua capillaries. Cov alveoli thiab capillaries ob leeg muaj cov phab ntsa nyias heev, uas tso cai rau cov pa oxygen dhau ntawm alveoli mus rau cov ntshav. Cov capillaries ces txuas mus rau cov hlab ntsha loj, hu ua veins, uas coj cov ntshav oxygenated los ntawm lub ntsws mus rau lub plawv.

Txoj kev twg ntawm cov kab mob sib xyaw ua ke cuam tshuam nrog cov kab mob bacteriophages?
Transduction, txheej txheem ntawm caj ces recombination nyob rau hauv cov kab mob uas cov noob los ntawm ib tug tswv tsev cell (ib kab mob) yog incorporated rau hauv lub genome ntawm ib tug kab mob (bacteriophage) thiab ces nqa. mus rau lwm lub xov tooj ntawm tes thaum tus kab mob bacteriophage pib lwm lub voj voog ntawm kev kis kab mob.
Braces puas cuam tshuam rau koj cov hlab ntsha?
Yog tias koj cov hniav tau muab tso rau nruj heev, lawv yuav ncab koj cov hlab ntsha, ua rau koj cov pob txha ntawm lub ntsej muag ua rau kev rub. Yog tias nws tsis tuaj yeem ua kom cov braces loosened, muaj lwm txoj hauv kev. Cov tshuaj kho mob xws li ibuprofen thiab tylenol tuaj yeem siv nrog rau caj dab thiab lub ntsej muag zaws kom txo qhov mob.
Cov kab kab kab kab kab ua kab mob txaus ntshai npaum li cas?
Nyob rau hauv peb thiab tom ntej instars ntawm lawv txoj kev loj hlob, Pine processionary caterpillars yog mob heev rau daim tawv nqaij ntawm tib neegthiab lwm yam tsiaj. Kev sib cuag yooj yim nrog cov plaub hau ntawm kab ntsig tuaj yeem ua rau pob khaus hnyav (urticaria) thiab khaus qhov muag, thiab qee tus neeg yuav muaj kev fab tshuaj.
Thaum cov kab mob kab mob nkag mus rau hauv cov hlab ntsha?
Kev kis kab mob nrog cov kab mob tsis tas ua rau kab mob. Kev kis kab mob tshwm sim thaum cov kab mob, kab mob, lossis lwm yam kab mob nkag mus rau hauv koj lub cev thiab pib sib kis. Kab mob tshwm sim thaum cov hlwb hauv koj lub cev puas lawm vim yog kis kab mob thiab cov tsos mob thiab cov tsos mob tshwm sim.
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.
