Double Femera shiri kunyanya gasi Exchange

The kufema maitiro shiri yepakutanga, riri dzakashandisa nguva ndege. Nani gasi Exchange iri muviri kunobatsira minhenga mweya miviri iyo kwakasimbiswa somugumisiro shanduka chinja.

Upper kufema turakiti

Air nzira iri shiri kunotanga glottal pakakoromoka, kuburikidza icho anopinda trachea. Part izvozvo, riri pamusoro - the dokeriro. Inonzi pamusoro, hapana basa inzwi kugadzirwa risingabereki kutamba. Voice shiri rinowanika mujinga pasi dokeriro, izvo chete neshiri. It riri uko trachea rakakamurwa principales maviri, uye inomirira uyewo, iyo rinotsigirwa kubva mapfupa marin'i.

Mukati dokeriro iri vasiyana masvingo Vocal membrane. Nokupesvedzera choristers tsandanyama yochinja configuration, iyo inosvitsa akasiyana-siyana zvenyika kurira. inzwi romukati Kamudzira vari pazasi pokuti trachea rinokamukana.

Upper kufema turakiti kunokosha kuti mutemo tembiricha muviri. Kupisa kunoita shiri kufefetera uye kazhinji shoma. tsinga iri pamuromo uye pahuro, vari kuwedzera. Somugumisiro muviri shiri inotonhodza kupa kupisa kusvika patinofemera kunze mhepo.

Mapapu uye mhepo SACS

Sechivako mumapapu shiri vakasiyana amphibians uye zvinokambaira, umo akafanana chinhu muhomwe. We watch fauna of muviri ichi wanamatira kumashure pechipfuva. In sezvamunoita afanane munhu batana chipanji. Mapazi principales vane jumpers - parabronchi yakawanda akafa-magumo migero (bronchioles) ayo vakaruka neboka guru richikurukura capillaries.

Vamwe principales bazi pashure vasapinda hombe mhepo SACS pamwe matete masvingo. Inzwi ravo zvikuru kupfuura chiedza. Mune shiri, dzimwe mhepo mabhegi:

• 2 remuromo,
• midclavicular,
• 4-6 thoracal,
• 2 abdominal.

Mipata vari pasi ganda uye zvakabatana pnevmatichnymi mapfupa.

Double Femera chiripo chaiyo nokuda mhepo mumasaga. Avo rubatsiro kufema mashandiro kunotemwa panguva kutiza.

kaviri mweya

Kuzorora shiri rinogarira inotevera yokuti mhepo mumapapu nekushanda netsandanyama. Kana achideredza sternum okisijeni-mupfumi gasi iri vakanwa kupinda kufema nenyere. Reverse inofamba mhepo tsandanyama iri kusundwa outwards. Light kunobatsirawo baya jekiseni oxygen.

A shiri inofamba kana anokwira, rinobatanidza mumhepo mabhegi riri peritoneum. Vari kumanikidza okumusoro zvikamu makumbo.

Anotiza, kukosha mhepo mumasaga anoramba kunowedzera nokuti nedanho kaviri shiri afemeruke. Kuwedzerwa rinotsvaka sezvinotevera:

1. Mapapiro vanomutswa, Munotatamura mhepo mumasaga.
2. Air anomanikidzwa mumapapu.
3. Part of gasi, pasina kumbomira, rakaitirwa mhepo SACS pasina kurasikirwa oxygen. Mumuviri uyu negasi Exchange kunoitika.
4. Mapapiro vari Haatauri expiratory gasi ichipfuura mumapapu, okisijeni-mupfumi mhepo kubva muhomwe.

A Chiitiko umo ropa oxygenated kuti fema uye exhale, ainzi kaviri mweya. It rine kukosha muupenyu shiri. Kufema anova kakawanda muwanze zvokutamba flapping mapapiro.

Zvimwe zviri kufema

Dual mweya chinoratidza shiri, asi uwandu shamhu uye vamwe kufamba kufema havana kufanana. Zvisinei, vamwe zvokukura azvaiitwa dzinoenderana nguva. Kuvapo mhepo Homwe kunobatsira kudzivirira overheating shiri kutiza, nokuti mhepo inotonhora runopoterera muviri kubva mukati. Uchibatsirwa wavo, akaderedza arambe achirema muviri uye kukweshera mitumbi imwe yacho. zvazvingava respiratoria kwakasiyana akasiyana mhuka. Vhoriyamu dzekudenga SACS, pachidanho pezvemakuriro mukuru mumapapu.
