Physiology ya Ntchito Zowonjezera

Gawo loyamba la kupuma , kutulutsa mpweya m'mapapu anu, amatchedwa kudzoza kapena inhalation . Kudzudzula kumachitika chifukwa cha minofu yaikulu yopuma yomwe imatchedwa diaphragm, yomwe ili pansi pamapapu mu nthiti.

Mitsempha ya Breathing

Mukamapanga, chifuwa ndi minofu pakati pa mgwirizano wanu wa nthiti, kumapangitsa kuti musamapanikizidwe - kapena kutuluka mkati mwa chifuwa chanu. Kupanikizika kumatulutsa mpweya umene mumapuma m'mapapu anu.

Kutsika kwa Mapulawa

Maungulo sali owala ngati mabuloni koma amapangidwa ndi siponji, minofu yosinthasintha yomwe imafafaniza pakadzazidwa ndi mpweya. Kotero, kodi mpweya umalowa bwanji mmenemo? Kodi amapita kuti? Tiyeni titsatire mpweya wa mpweya kuyambira pachiyambi mpaka kumapeto.

Kutenga Mpweya

Mukapuma, mpweya umalowa kudzera mu mphuno ndi pakamwa ndipo umayenda pansi pamtima, kudzera mu bokosi lanu la mawu ndi mu trachea, yomwe imadziwikanso ndi windpipe.

Kulowa M'mapula

Mapeto a trachea anu amagawanika kumbali ya Y-mawonekedwe ndikupanga bronchi. Mpweya umadutsa pambali kumbali zonse ziwiri za mapapo.

Kulowa Mtengo wa Bronchial

Mkati mwa mapapu, bronchi amayambira ku bronchioles , omwe amawoneka ofanana ndi nthambi za mtengo.

Kuthamangira ku Bronchioles

Mlengalenga umayenda kudzera mu bronchioles, yomwe imakhala yaying'ono mpaka mpweya ukufika kumapeto kwa nthambi.

Kudzaza Mitengo ya Air

Kumapeto kwa bronchioles ndi masango aang'ono omwe amatenga mpweya, wotchedwa alveoli.

8 -

Gas Exchange

Mphepo ikafika pa alveoli , mpweya umagawidwa kudzera mu membrane m'mitsempha yaing'ono yotchedwa capillaries, ndipo carbon dioxide imasiyana ndi magazi omwe ali m'magazi a capillaries kupita ku alveoli.

Kuzimitsa Zonsezi

Gawo lachiwiri lakupuma, kutulutsa mpweya kuchokera m'mapapo, amatchedwa kutha kapena kutuluka . Akatha mpweya ndi carbon dioxide malonda amapezeka mu alveoli, chotupacho chimasokoneza ndipo chifuwachi chimabwezeretsedwa ku chifuwa. Izi zimalimbikitsa mpweya wogwiritsidwa ntchito m'mapapo, kutsogolo kwa njira yomwe idagwiritsire ntchito m'mapapo. Kupuma konse kumabwerezedwa 10 mpaka 20 pa mphindi pa munthu wathanzi wathanzi.
