Yog vim li cas yog tsa caj npab daj, flushed thiab nws txo qis? Yog vim li cas disturbing tshwm sim

Peb lub cev - ib tug complex system nyob rau hauv uas txhua hloov ua nws txoj kev ua. Tiam sis tag nrho lub Cheebtsam ntawm tus tib neeg lub cev yog ua tau hauj lwm xwb ua tsaug rau ib tug, feem ntau lub caij tseem ceeb - plawv. Qhov no nqaij yog lub luag hauj lwm rau cov ntshav mov rau ntaub so ntswg thiab kabmob, tsis muaj nws tsis muaj lub neej, nws "ua hauj lwm" ua rau loj kab mob. Paub txog yuav ua li cas lub plawv ua hauj lwm, yuav pab ib tug neeg ua hauj lub zoo tshaj plaws tseem ceeb heev kev ua si. Tsis tas li ntawd, nws yuav pab kom koj paub thiab to taub yog vim li cas nyob rau hauv tej rooj plaub lub cev nqua tig daj ntseg los yog ntsej mua nce ntshav. Piv txwv li, yog vim li cas tsa tes muab daj ntseg thiab nws txo qis blushed? Cov cuab teb cov lus dag nyob rau hauv qhov yooj yim kev txawj ntse ntawm lub plawv thiab cov kev cai ntawm physics. Thaum analyzed hauj lwm ntawm cov kev mob plawv, cov neeg yuav to taub vim li cas qhov no yog li ntawd thiab seb nws yog dab tsi. Luv luv lom pom yuav pab tau rau cov menyuam yaus thiab cov neeg laus.

Lub plawv - lub twj tso kua mis ntawm tus tib neeg lub cev

Lub plawv ua hauj lwm yog heev uas zoo sib xws rau cov kev ua ntawm lub twj tso kua mis, uas twj hauv cov ntshav thiab muab nws thoob plaws lub cev. Ntshav nourishes kabmob tseem ceeb heev thiab ntaub so ntswg. Nws khoom siv oxygen nyob rau hauv lawv thiab tus tsim nyog cov ntaub ntawv. Qhov no tsis muaj tseem ceeb heev kev ua si ntawm tus neeg yog tsis yooj yim sua. Lub plawv mob muaj plaub compartments: txoj cai atrium thiab ib tug coj ventricle (txoj cai), sab laug atrium thiab ib tug coj ventricle (sab laug).

Txhua sab ntawm lub plawv yuav cov siv ntawm cov ntshav nyob rau hauv tej yam cov hlab ntsha, cov leeg thiab cov hlab ntsha. Stroke ntshav thoob plaws lub cev yuav tsum tau muab faib mus rau hauv me me thiab cov loj loj voj voog. Ntshav nkag mus rau hauv lub ntsws, yog enriched nrog rau oxygen thiab tseem nws txoj kev los ntawm lub cev. Tom qab hais tias, nws ib zaug dua ntog mus rau hauv lub pulmonary leeg thiab rau lub voj voog dua. Uninterrupted txaus ensured los ntawm ib tug muaj zog mob nqaij co ntxias lis dej thoob plaws hauv lub neeg lub neej voj voog. Paub txog physiology ntawm lub plawv dhia, koj yuav to taub vim li cas tus tsa tes muab daj ntseg thiab nws txo qis blushed.

Cawv ntawm Newton txoj cai

Tag nrho lub ntiaj teb no yog nyob rau hauv tus ntawm lub ntiajteb txawj nqus. Lub circulatory system ntawm tus neeg tsis yog ib qho kev zam. Yog hais tias lub cev tsis muaj ib tug tshwj xeeb lub plawv li qub, cov ntshav yuav tsuas noog nyob rau qhov hauv qab vim gravitational attraction. Qhov tshwj xeeb jumpers thiab nqaij txhawb teeb tis ntawm cov ntshav. Qhov tseeb thiab qhov kev paub ntawm cov anatomical qauv ntawm lub plawv ua rau nws tau to taub yog vim li cas lub tsa tes muab daj ntseg thiab nws txo qis blushed. Yuav ua li cas yog vim li cas rau qhov no tshwm sim? Newton txoj kev cai.

Yog vim li cas yog tsa caj npab daj, flushed thiab nws txo qis?

Thaum ib tug neeg picks lub povtseg, cov ntshav yuav ua tsis nyob rau tib tus nqi nkag mus rau lub sab saum toj feem. Nws khiav yog slowed down vim lub ntiajteb txawj nqus. Yog hais tias koj tuav ib tug tes tsa rau ib ntev lub sij hawm, nws tsis yog cia li daj ntseg, tab sis kuj loog. Nws txo qis extremity, on qhov tsis tooj, yuav pib tau txais ntau heev cov ntshav. Vim li no, cov leeg nyob rau hauv nws caj npab tej zaum yuav swell thiab redden ntawm daim tawv nqaij. Cov kev cai ntawm physics thiab lub chaw ua hauj lwm ntawm lub plawv los mus piav qhia qhov no tshwm sim yog yooj yim. Panic txhawj txog nws. Qhov no yog heev qub povtseg tes txoj hauj lwm upwards los yog downwards.

Paub qhov yooj yim zog ntawm lub plawv thiab cov yuav ua li cas khiav lag luam yog cov gravitational rog ntawm lub ntiaj teb, muaj txhua tam sim no yuav tsum tau to taub yog vim li cas lub tsa tes muab daj ntseg thiab nws txo qis blushed.
