Engtin nge thisen hi i taksa pum puiah a kal? (Blood Flow and Circulatory System) A awlsam zawngin i hrechhuak ang u!

He thisen an tih hi engtin nge harsatna awm lovin kan taksa a fang kual vel tih hi i chawlhsan tawh em? Mak a ni lo maw? Kan thinlung a thawk second tin hian he pump te tak te hian kan taksa pum puia tube system hmangin thisen chu a kalpui thin. Hei hi ` Circulatory System` kan tih chu a ni. Heng tube te hi rubber tube flexible ang mai a ni a, taksa peng tenau zawng zawngah thisen a phur a ni. Okay, chuti a nih chuan he thu hi chipchiar deuhin han sawi ila?

Engvangin nge thisen hi kan tan a hlu em em?

Thisen hi kan nunah thil pawimawh tak a ni tak zet a ni. Ngaihtuah teh, he thisen hian kan taksa chhunga cell leh tissue tenau zawng zawngte chu nung leh hnathawh theihna tura puitu chu a ni. Thisen chungchanga thil thleng lian ber berte chu hetiang hi a ni:

• Thisen hian kan taksa chhunga tissue hrang hrangah oxygen leh nutrient pawimawh tak tak a phur a, chu chu kan in chhunga ei leh in tur a rawn keng tel ang bawkin.
• Thisen hian duh loh carbon dioxide leh bawlhhlawh dang tissue-a lo awm khawmte chu paih chhuakin taksa atanga paih chhuak turin a pui bawk a, chu chu i in chhunga bawlhhlawh paih chhuah ang bawkin a ni.
• Chuvângin, heng zawng zawng avâng hian kan nun vawng nung tûr leh kan taksa peng tinreng hrisel taka awmtîr nân thisen hi a pawimawh hle a ni .

Thisen hlu zia i hrethiam em?

Thisen kalna kawng hi chi thum a awm a!

Kan taksaah hian thisen kalna kawng chi thum a awm a, chungte chuan he thisen hi a che thei a ni. Kawngpuiah hian kawngpui lian, kawngpui te, leh kawngpui sir a awm ang bawkin.

1. Arteries – thinlung atanga thisen thianghlim phurtu thisen kalna kawng (vessels).

Arteries chu kan thinlung atanga taksa chhunga tissue dang zawng zawnga oxygen tamna thisen (diagram-a sen-a lang tlangpui) leh nutrients phurtu thisen kalna kawngte a ni. Thinlung chu tui pump ang maiin ngaihtuah la, artery te chu chu pump atanga tui thianghlim huan pum puia phurtu pipe lian tak tak ang mai a ni.

• He arterial system hi aorta atanga tan a ni a, chu chu thinlung atanga thisen kalna kawng lian ber a ni. Tui dahna lian ber atanga pipe lian ber chhuak ang mai a ni.
• Chungte chuan thinlung atanga oxygen tamna thisen chu taksa tissue zawng zawngah an phur a.
• Thinlung atanga i hlat deuh deuh chuan heng thisen kalna kawngte hi hnah hrang hrangah an inthen a, zawi zawiin an lo te zawk thin. Lui lian tak chu lui lian lo zawka a inthen ang bawkin.

Chuvangin, arteries hnathawh ber chu taksa pum puia thisen tha sem chhuah hi a ni .

2. Capillaries – inthlengna hmun tenau ber

Capillaries hi thisen kalna kawng te tak te, fim tak tak network a ni. Chungte chu thisen kalna kawng lian zawk pahnih, thisen kalna kawng leh thisen kalna kawngte inzawmkhawmtu a ni. Kawngpui lian pahnih inkar kawngpui te tak te inzawmkhawm angin han ngaihtuah teh.

• Heng capillary te bang hi a te hle a, mesh ang mai a ni.
• Heng bang te tak te te hian thil tha oxygen leh nutrient te chu thisen atanga tissue cell ah a kal tir thei a, thil duh loh carbon dioxide leh tissue cell atanga bawlhhlawh lo chhuak te chu thisenah a kir leh thei bawk Market-a thil inthleng ang mai a ni.

Dik tak chuan, taksa cellular level-a he inthlengna pawimawh tak hi heng capillary te tak te hmang hian a thleng a ni . An te lutuk a, a nihna takah chuan capillary thenkhat chu kan sam aiin a hring zawk! Mahse an hnathawh hi a lian hle a ni lawm ni?

3. Veins – thisen thianghlim lo chu thinlunga phur kir lehtu vessel

Vein hi thisen kalna kawng a ni a , oxygen tlakchham, a nih loh leh thisen "bawlhhlawh" (diagram-a blue-a tarlan tlangpui) atanga kan taksa tissue atanga thinlung lam pan leh thin. Tui hman tawhte khawlkhawm a, tank-a dah kir lehtu pipe system ang mai a ni.

• HeiThisen kalna kawngte hian taksa tissue atanga thisen oxygen tlem leh carbon dioxide tamna chu thinlungah a phur kir leh thin.
• Heng vein te hi thinlung hnaih deuh deuh hian an inzawm khawm a, an lian chho zel a ni. Lui te te an inzawm khawm a, lui lian tak an siam ang bawkin.
• A tawp berah chuan vein lian tak `superior vena cava` an tih hian lu leh kut atanga thisen chu thinlungah a rawn hruai lut a. Chutiang bawkin vein lian tak `inferior vena cava` an tih hian pum leh ke atanga thisen chu thinlungah a rawn hruai lut thin.

Chuvangin veins hnathawh ber chu thisen awmna bawlhhlawh taksaa awm khawmte chu thinlungah hruai kir leh a , tihthianghlimna tura kaihhruai hi a ni

He thisen kalna kawng hi i ngaihtuah aiin engzat nge a lian?

Tunah chuan kan taksaa thisen kalna kawng, thisen kalna leh thisen kalna (capillaries) system chu a buaithlak zia i hmu thei tawh ang. Thisen kalna kawng zawng zawng – chu chu thisen kalna kawng zawng zawng, thisen kalna kawng zawng zawng, leh thisen kalna kawng zawng zawng inzawmkhawm – chu mel 60,000 chuang zeta sei a ni tih i hria em ! Kan thisen hi he system lian tak hmang hian a luang chhuak fo thin. Khawpui chhunga kawngpui network ang mai a ni a, car pawh a kal leh chhuak fo thin. Chuvangin he thisen zawng zawng hi taksa pum puia pump chhuak tura puitu chu kan thinlung hi a ni . He thil kalphung zawng zawng hi a mastermind a ni.
