Cardiovascular vs Circulatory System
Cov kab mob plawv feem ntau hu ua circulatory system vim muaj cov yam ntxwv sib koom los ntawm ob lub cev. Piv txwv li, ob lub cev muaj xws li lub plawv thiab ntshav, thiab lub luag haujlwm tseem ceeb ntawm ob lub cev yog thauj khoom thoob plaws hauv lub cev los ntawm cov hlab ntsha.
Lub Kab Mob Ntshav Qab Zib yog dab tsi?
Cov kab mob plawv, raws li lub npe qhia, muaj ob lub ntsiab lus tseem ceeb; lub plawv (uas txhais tau tias cardio) thiab cov hlab ntsha (uas txhais tau tias vascular). Lub plawv yog lub twj tso kua mis uas ua rau lub zog contractile txhawm rau faib cov ntshav thoob plaws hauv lub cev. Tsis tas li ntawd, lub plawv txuas ob leeg pulmonary thiab systemic circulatory systems. Cov hlab ntsha muaj xws li cov hlab ntsha, cov hlab ntsha, cov hlab ntsha, cov hlab ntsha, thiab cov hlab ntsha me me uas ua rau cov hlab ntsha hauv lub cev. Lub luag haujlwm ntawm cov hlab ntsha no yog nqa cov ntshav los ntawm lub plawv mus rau hauv nruab nrog cev thiab hloov pauv. Lub luag haujlwm tseem ceeb ntawm cov hlab plawv yog xa ntau yam tshuaj thiab tshem tawm cov khoom pov tseg hauv lub cev.
Circulatory System yog dab tsi?
Circulatory system feem ntau suav nrog lub plawv, cov hlab ntsha, ntshav, lymph thiab lymph hlab ntsha. Nyob rau hauv tib neeg, lub circulatory system yog ib tug kaw system uas muaj lub plawv, thiab ob circulatory ceg, namely, pulmonary ncig thiab systemic ncig. Lub luag haujlwm tseem ceeb yog zoo ib yam li cov kab mob plawv. Cov kab mob pulmonary feem ntau nqa cov ntshav mus rau alveoli hauv lub ntsws, thaum lub cev ua haujlwm nqa cov ntshav mus rau txhua yam ntaub so ntswg thiab lub cev hauv lub cev. Ob lub tshuab yog tsim los ntawm cov hlab ntsha nrog rau cov hlab ntsha, cov hlab ntsha, cov hlab ntsha, venules thiab capillaries. Cov ntshav ua raws li kev thauj khoom ntawm cov hlab ntsha. Peb lub luag haujlwm tseem ceeb ua los ntawm cov ntshav yog kev thauj mus los ntawm cov pa roj xws li oxygen thiab carbon dioxide, cov khoom noj khoom haus, cov khoom siv hauv cov metabolism, kev tswj hwm lub cev kub, pH ib txwm muaj, cov dej ntim thiab siab, thiab tiv thaiv kab mob thiab ntshav poob. Cov hlab ntsha thiab cov hlab ntsha tuaj nyob rau hauv cov kab mob lymphatic, uas qee zaum suav tias yog ib qho ntxiv rau cov hlab ntsha. Lwm yam tshaj li cov qog ntshav thiab cov hlab ntsha, lub cev kuj muaj cov qog nqaij hlav, tonsils, spleen, thymus caj pas, Peyer's thaj ua rau thaj, lacteals, thiab lymphoid cov ntaub so ntswg. Cov kua dej lymphatic thiab interstitial yog qhov nruab nrab ntawm cov ntshav thiab cov ntaub so ntswg. Lymph hlab ntsha yog lub luag haujlwm rau kev thauj mus los ntawm cov ntaub so ntswg ntau dhau mus rau hauv cov hlab ntsha. Tsis tas li ntawd, cov qog ntshav qog tsim cov lymphocytes uas tseem ceeb rau kev tiv thaiv cov kab mob.
Qhov txawv ntawm Kab Mob thiab Kab Mob Kab Mob yog dab tsi?
• Cov kab mob plawv feem ntau suav nrog lub plawv thiab cov hlab ntsha, qhov circulatory system muaj xws li cov ntshav, cov hlab ntsha, lub plawv, lymph thiab lymph hlab ntsha.
• Tsis zoo li cov kab mob plawv, cov kab mob circulatory piav ntau lub zog.
