Cov circulatory system yog ua los ntawm ntshav cov nkoj uas nqa ntshav deb ntawm thiab mus rau qhov plawv . Cov hlab ntsha nqa ntshav deb ntawm lub lub plawv thiab cov hlab ntsha nqa ntshav rov qab mus rau lub plawv . Cov circulatory system nqa oxygen , cov as -ham, thiab cov tshuaj hormones rau cov cell, thiab tshem tawm cov khoom pov tseg, xws li carbon dioxide.
Ua kom pom qhov no, dab tsi yog qhov ua haujlwm ntawm cov hlab ntshav?
Cov circulatory system , kuj hu ua cov hlab plawv los yog lub cev lawv , yog lub cev lawv uas tso cai rau cov ntshav mus ncig thiab thauj cov as -ham (xws li cov amino acids thiab electrolytes), oxygen, carbon dioxide, cov tshuaj hormones, thiab cov qe ntshav mus thiab los ntawm cov cell hauv lub cev los muab kev txhawb nqa thiab pab hauv
Dhau li saum toj no, dab tsi yog lub circulatory system? Cov circulatory system yog muaj los ntawm lub plawv thiab cov hlab ntsha, nrog rau cov hlab ntsha, cov hlab ntsha, thiab capillaries.
Ib tus kuj tseem yuav nug tau, dab tsi yog cov txheej txheem hauv lub cev yooj yim txhais?
Cov circulatory system yog txhais raws li lawv uas txav ntshav, oxygen thiab cov as-ham los ntawm lub cev. Piv txwv ntawm circulatory system yog kev ua haujlwm ntawm tib neeg lub plawv, ntshav thiab cov hlab ntshav.
Cov hlab ntsha puas yog lub cev?
Cov leeg yog cov hlab yas, lossis cov hlab ntshav, uas nqa ntshav los ntawm koj lub cev thiab cov ntaub so ntswg ntawm lub cev rov qab los rau koj lub siab. Txhua leeg yog tsim los ntawm peb txheej: Ib txheej ntawm cov ntaub so ntswg nyob sab hauv.
Pom zoo:
Dab tsi tsuas yog lim los ntawm cov hlab ntshav los ntawm glomerulus thiab tsis rov qab nqus mus rau hauv cov hlab ntshav tab sis tawm los ntawm cov zis?
Creatinine yog cov khoom pov tseg los ntawm cov leeg tawg thiab raug tshem tawm los ntawm cov ntshav los ntawm glomerulus ntawm nephron. Nws tsuas yog cov khoom uas tsuas yog lim tawm ntawm cov ntshav tab sis TSIS tau rov ua dua rau hauv lub cev. Nws raug tso tawm los ntawm cov zis
Dab tsi yog txoj hauv kev ntawm cov ntshav los ntawm txoj hlab ntshav ncig?
Coronary circulatory system, ib feem ntawm cov kab ke ua haujlwm hauv lub cev uas muab cov ntshav mus rau thiab muab cov kua ntws los ntawm cov nqaij hauv plawv. Deoxygenated ntshav raug xa rov qab mus rau hauv chav ntawm lub plawv los ntawm cov leeg hlab plawv; Feem ntau ntawm cov no sib sau ua ke tsim cov hlab ntshav venous, uas ntws mus rau sab xis atrium
Hom hlab ntshav twg txuas cov hlab ntsha thiab cov hlab ntshav?
Hom hlab ntsha Capillaries yog feeb nyias-walled hlab ntsha uas txuas cov hlab ntsha thiab venules; Nws yog los ntawm cov capillaries uas cov as-ham thiab cov pov tseg tau pauv ntawm cov ntshav thiab cov ntaub so ntswg ntawm lub cev
Cov hlab ntsha hlab ntsha thiab cov hlab ntshav muaj dab tsi?
Cov hlab ntsha nqa ntshav tawm ntawm lub plawv; Lub ntsiab hlab ntsha yog aorta. Capillaries nqa ntshav tawm ntawm lub cev thiab pauv cov as-ham, pov tseg, thiab oxygen nrog cov ntaub so ntswg ntawm qib cellular. Cov leeg ntshav yog cov hlab ntshav uas coj cov ntshav rov qab los rau hauv lub plawv thiab tso ntshav tawm ntawm cov kabmob thiab cov ceg
Cov kua ntshav ntshav yog dab tsi tom qab cov qe ntshav thiab cov ntshav khov tau raug tshem tawm?
Cov ntshav yog cov kua ntshav tom qab cov qe ntshav thiab cov protein sib xyaw tau raug tshem tawm. cov pa roj ntshav suav nrog oxygen, carbon dioxide, thiab nitrogen
