Kan taksa engine mak tak mai: Thinlung chungchang engkim i zir vek ang u!

Hun reh takah i rilruah i kut i nghat a, i mit i chhing a, i ngaithla ngai em? Chu "lub-dub... lub-dub..." ri i hriat leh hriat chu i dam tih finfiahna lian ber a ni. Chu aw chu kan taksaa engine mak ber, tawp ngai lo atanga lo chhuak a ni. Chu chu kan thinlung a ni. He taksa peng te tak te, kan pian ni atanga kan thih ni thlenga second khat pawh chawlh nei lovin hna thawk thin hi kan hre tak tak em? Vawiin hian kan nun tak tak innghahna thinlung duhawm tak hi han sawi ila.

Thinlung chu eng nge ni? Taksa tan eng rawngbawlna nge a pek?

A awlsam zawngin, thinlung hi i kutphah ang vela lian, taksa peng chak tak, taksa peng lian tak a ni. Khawpui chhunga bus station lian ber ang maia kan taksa pum puia thisen kalna hmunpui ber a ni. Circulatory system kan ti bawk.

Thinlung hnathawh ber chu taksa pum puia thisen pump chhuah hi a ni. Tunah chuan, "Chuti a nih chuan thisen pump chhuah hian eng nge thleng?" Ngaihtuah teh, kan taksaa cell tenau maktaduai tam takte hian an hnathawh theih nan chakna leh oxygen an mamawh a ni. Nunna atana ei leh in leh thaw kan mamawh ang bawkin. Chuvangin thinlungin thisen a pump chhuah hi he oxygen leh nutrients te hi la in taksa chhunga cell tinah a sem darh thin a ni. Tin , bawlhhlawh carbon dioxide ang chi , cell-a an hnathawh laiin a awm khawm a, a kaihhnawih taksa peng hrang hrang (lung leh kal ang chi)-a paih chhuah tura thlentu a ni bawk.

Chu mai ni lovin, thinlung hian hna pawimawh dang engemaw zat a thawk a:

• Heartbeat rhythm leh speed a control thin. Kan thluak leh nervous system hian kan thinlung chu kan mut laiin a thawk zawi zawk a, kan tlan laiin rang zawk turin a hrilh bawk.
• Blood Pressure a control thei a ni. Tin, thisen kalna kawng chhunga pressure awm chu a level dik taka vawn reng hi thinlung mawhphurhna a ni bawk.

He hna hi tha taka thawk turin thinlung hian amah chauhin hna a thawk lo. Kan nervous system leh endocrine system te hian thinlung nen hna an thawk dun a. Nervous system hi kan hlauhthawn emaw, kan hlim lai emawa kan thinlunga chak zawk tura signal pe tu, kan rilru hahdam laia kan slow theihna tur signal pe thintu a ni. Endocrine system atanga hormone chhuak hian thisen kalna kawng a tikhawlo emaw, a tizau emaw a, thisen sang control nan a pui thin.

Thinlung thenkhat chu kan la hrang ang em?

Thinlung hi in duan tha tak ang mai a ni. Bang, pindan, kawngkhar, tui pipe leh electric wire system a nei a. Pakhat hnu pakhatin han thlir ila.

A bang leh thinlung venhimna khuhna

Thinlung bangte hi thisen pump turin taksa peng hrang hrang inzawmkhawm leh zau zawkte an ni. Heng bang lai takah hian tissue thuk tak a awm a, chu chu septum kan ti a ni. Hei hian thinlung chu dinglam leh vei lamah a then a ni.

Heart wall hi layer lian pathum atanga siam a ni a:

• Epicardium: Hei hi pawn lam venhimna layer a ni.

Thinlung pum pui chu venhimna bawm pericardium an tih ah a khuh leh ta a ni . He sac chhunga tui bik hian thinlung chu a beng laiin taksa peng dang a tawk lo va, a glide thei a ni.

Thinlung Chamber Pali te chu

Thinlung chhungah hian main chamber pali a awm a. Chhawng chung berah chamber pahnih leh a hnuai lamah chamber pahnih a awm bawk. In chhawng hnih nei ang maiin. Chhawng chungnung lama chamber awmte chu Atria kan ti a , a hnuai lama chamber awmte chu Ventricles kan ti bawk .

Thinlung Valve te

Thinlung pindan inkara thisen a kal leh chhuah rual hian, kawng dik lo lama a luang leh loh nan kawngkhar system a awm a. Heng gate te hi ``Valves`` kan ti thin. Heng kawngkharte hi kawng khata thisen a luang chuan a inhawng a, thisen thenkhat a kal tawh chuan nghet takin khar leh thin a ni.

Valve hi chi li a awm a, chungte chu:

• Tricuspid valve: Atrium dinglam leh ventricle dinglam inkar kawngkhar.
• Pulmonary valve: Ventricle dinglam atanga lung lam panna thisen kalna kawng hawnna.
• Mitral valve: Left atrium leh left ventricle inkar kawngkhar.
• Aortic valve: Main artery (Aorta) bul tanna gate, veilam ventricle atanga taksa pum puia thisen phurtu.

Thisen kalna kawng hrang hrang

Thinlung atanga thisen pump chhuah taksa pum puia phurtu leh thinlunga phur kir lehtu tube system hi ``Blood Vessels.`` kan ti a, chungte chu chi thum an ni.

• Arteries: Hei hi thinlung atanga taksa peng dang thlenga oxygenated thisen phurtu tube thuk tak tak te an ni.
• Veins: Hei hi taksa peng hrang hranga hman thin oxygen tlakchhamna nei lo thisen thinlunga phur kir lehtu tube te an ni.
• Capillaries: Thisen kalna kawng te tak te, sam ang maia sei, thisen kalna kawng leh thisen kalna kawng inzawmkhawm. Heng capillary chhungah hian cell te hian oxygen an dawng a, carbon dioxide an paih chhuak thin.

Thinlung 'current' - engtin nge he vuakna hi thunun a nih?

Thinlung hi tisa zungbun mai a ni lo. Electrical system bik ``Electrical Conduction System'' tih a nei a, chu chuan rhythm mumal takin a beat reng a ni. In chhunga wiring system ang mai a ni.

He system-ah hian thil pawimawh engemaw zat a awm a:

• Sinoatrial (SA) node: Hei hi thinlunga natural pacemaker a ni. Thinlung chu engtiang chiahin nge a beng tur tih hrilhtu electrical signal chu hetah hian a intan a ni.
• Atrioventricular (AV) node: Hei hian SA node atanga signal chu a la a, a tikhawtlai deuh a, thinlung hnuai lam chamber (atria) pahnih ah a thawn chhuak thin.
• A hmun dang (Bundle of His, Purkinje fibers): Hengte hian AV node atanga signal lo lut chu thinlung hnuai lam chamber zawng zawngah an phur a, chu chuan an inzawm nghal vek a ni.

Chutiang chuan a chung lam chamber pahnih chu an inzawm khawm a, thisen an pump hnuah second sawma ṭhena hmun khat chhungin a hnuai lam chamber pahnih chu an inzawm khawm a, taksa leh lungah thisen an pump chhuak a ni. He electrical system-ah hian tihsual tlem a awm chuan heartbeat mumal lo (arrhythmia) a awm thin.
