Diastole thiab systole cov yog ob theem ntawm lub plawv dhia. Lawv tshwm sim raws li plawv neeg ntaus, tso ntshav los ntawm cov hlab ntshav uas nqa ntshav mus rau txhua qhov ntawm lub cev. Systole tshwm sim thaum lub plawv ntawv cog lus los tso ntshav tawm, thiab diastole tshwm sim thaum lub plawv relaxes tom qab kev cog lus.
Kuj nug, dab tsi yog systole ntawm lub plawv?
Systole , lub sij hawm ntawm kev cog lus ntawm lub ventricles ntawm plawv uas tshwm sim ntawm thawj thiab thib ob plawv suab ntawm lub plawv dhia (ntu ntawm cov xwm txheej hauv ib leeg plawv tuav). Systole ua rau cov ntshav tawm mus rau hauv lub aorta thiab cov hlab ntsws. Saib kuj ntshav siab.
Ib tus kuj yuav nug, systole thiab diastole ntshav siab yog dab tsi? Tus naj npawb sab saum toj yog hais txog tus nqi ntawm siab hauv koj cov hlab ntsha thaum lub zog ntawm koj cov leeg nqaij. Qhov no hu ua systolic siab . Tus lej hauv qab yog hais txog koj ntshav siab thaum koj lub plawv nqaij nyob nruab nrab ntawm cov neeg ntaus. Qhov no hu ua siab diastolic.
Ib yam nkaus, ua li cas systolic thiab diastolic ntshav siab cuam tshuam nrog lub plawv dhia?
Thoob plaws hauv plawv plawv , cov ntshav siab nce ntxiv thaum lub sijhawm ua haujlwm ntawm lub plawv dhia qis thiab txo qis thaum lub plawv dhia puv thiab atrial systole cov . Yog li, muaj yog ob hom kev ntsuas ntshav siab : systolic thaum lub sij hawm contraction thiab diastolic siab thaum so.
Yuav ua li cas tshwm sim thaum lub sij hawm ventricular systole?
Raws li, thaum lub plawv chamber tau so (diastole), cov ntshav yuav ntws mus rau hauv atria los ntawm cov hlab ntsha, uas yog siab dua. Thaum lub sij hawm ventricular systole , siab nce hauv ventricles , tso ntshav rau hauv lub ntsws ntsws los ntawm sab xis ventricle thiab nyob rau hauv lub aorta ntawm sab laug lub plawv.

Lub plawv muaj plaub chav: Txoj cai atrium tau txais cov ntshav los ntawm cov leeg ntshav thiab tso nws mus rau sab xis. Txoj hlab ntshav sab xis tau txais cov ntshav los ntawm txoj cai atrium thiab tso nws mus rau lub ntsws, qhov uas nws muaj cov pa oxygen. Sab laug atrium tau txais cov pa oxygen los ntawm lub ntsws thiab tso nws mus rau sab laug lub ntsws
