I thinlunga kawngkhar te tak te i zir ang u? Pulmonary Valve a ni ta!

Chibai! I dam em? Vawiin hian kan thinlunga thil pawimawh tak, mahse kan sawi vak lo mai thei thil pakhat kan sawi dawn a ni. Kan in kawngkhar ang mai a ni. Pulmonary valve an ti a. He kawngkhar te tak te atang hian eng thil nge thleng tih, a pawimawh zia i en ang u.

Pulmonary Valve hi eng nge ni? A awlsam zawngin i hrethiam ang u!

I thinlung hi in te tak te, pindan pali nei angin ngaihtuah rawh. Pindan khat atanga pindan danga thisen a luang chhuak tur chuan kawngkhar a awm a ngai a ni lawm ni? Chu chu pulmonary valve chu a ni. Thinlung chhunga valve pali zinga pakhat a ni. A dik zawka sawi chuan, i thinlung dinglam chamber hnuai lam (``right ventricle'' an tih) atanga oxygen tlachham thisen chu ``main pulmonary artery'', oxygen tlachham thisen lung chhunga phurtu thisen kalna kawng lian ber thlenga hruai chhuaktu 'kawngkhar' a ni. He thisen hian lung a thlen chuan oxygen a la khawm thin. Tichuan, chu thisen oxygen tamna chu taksa peng dang zawng zawngah a kal ta a ni. Chuti a nih chuan, he kawngkhar hi dik taka hnathawh a pawimawhzia i ngaihtuah thei em? Pulmonary valve hi kan thinlunga valve dang, ``aortic valve'' nen hian an vaiin ``semilunar valves'' an ti a. Hei hi a chhan chu heng valve-a flap (kawngkhar khar ang chi) te hi crescent ang maia siam a nih vang a ni. Heng crescent valve te hian kan thinlung chamber hnuai lam (ventricles) atanga thisen kalna kawng lian zawk (arteries)-a thisen kal dan chu an control a ni. Pulmonic valve an tih pawh i hre mai thei. An pahnih hian thil pakhat hming an ni.

Chuti a nih chuan he pulmonary valve hian eng nge a tih tak tak?

He pulmonary valve hnathawh ber chu kan sawi tawh ang khan thinlung ventricle dinglam atanga main pulmonary artery thlenga oxygen tlachham thisen kal dan control hi a ni. Hetiang thil thleng dan hi chipchiar deuhin han thlir ila:

• I thinlung a na apiangin he pulmonary valve hi a inhawng a, a khar a, kawngkhar ang maiin a inhawng bawk.
• I ventricle dinglam a inzawm khawm chuan (hei hi damdawi lam tawng chuan ``systolic phase'' an ti a) pulmonary valve a inhawng thin. Hei hi thinlung atanga thisen a luang chhuak tan a, lung lam hawiin a luang chhuak tan a ni.
• Tichuan, thinlung chu rei vak lo a ‘relax’ chuan (hei hi ``diastolic phase'' emaw relaxation phase emaw an ti a, pulmonary valve chu a khar ta a ni. Hei hi a pawimawh hle. A chhan chu hetianga a khar loh chuan lungah thisen kal tawh chu thinlungah a leak leh thei a ni. Chu chu a tha lo.
• Chuvangin, he valve hi khar a nih chuan ventricle dinglam chu a vawi khatna atana a contract tur thisen nen a khat ta a ni.

Tui tap ang maiin han ngaihtuah teh. I mamawh hunah i hawng a, tui i la lut a, i tih zawh chuan i khar bawk. Chutiang a nih loh chuan tui chu a chhe vek mai. Pulmonary valve pawhin chutiang bawk chuan thisen kal dan a control bawk.
