The kufema maitiro shiri: basa, mamiriro

The kufema maitiro shiri nemamwe. Ini watch mhepo aibuda kuenda divi rimwe chete, izvo zvisiri yo dzimwe vertebrates. Ndingaita sei kufema nokubuda kuburikidza trachea? The mhinduro iri mubatanidzwa haashamisi kuti rakasiyana nemamwe anatomical zvinhu uye mhepo yakapoteredza nekubudisa evanhu. Mamiriro Akaita kufema wemuTesitamende shiri kuti kunzwisisa nzira dzedenga mumasaga. Havasi panguva mhuka.

The kufema maitiro shiri: anorimwa

Process mu rwendo akaita zvakasiyana pane ari mhuka. Kuwedzera nomumapapu, ivo vaiva mhepo muhomwe. Zvichienderana mhando, shiri kufema maitiro zvingasanganisira nomwe kana vapfumbamwe mashizha izvi, izvo kuwana papfudzi uye mapfupa pelvic, musana uye kunyange dehenya. Nokuda kwokushayiwa mhepo kukuchidzirwa diaphragm anochinja nevamwe dzedenga mumasaga achishandisa pectoral netsandanyama. Izvi zvinoitawo kuti kunaka nevamwe zvipande, zvichiita mhepo kupinda kufema hurongwa. Zviito akadaro kwete kungogara. Ivo zvinoda mumwe sunga tsandanyama kuwedzera kuita mudenga SACS uye ejecting mhepo panze.

The nemamiriro kufema wemuTesitamende shiri kunosanganisira nokusimudza sternum panguva kwacho. Shiri Light regai vawedzere kana chibvumirano sezvo mammalian miviri. In mhuka, kupanana okisijeni uye carbon dioxide inobvisa kunoitika muna nemaziso SACS, akadana Formação de. In mapapiro hama gasi Exchange rinoitwa mukati mamasvingo sepombi tuduku inonzi capillaries mhepo. Respiratoria shiri kuita nani kupfuura mhuka. Vanokwanisa kutakura zvakawanda okisijeni nomumwe mweya. Kana zvichienzaniswa mhuka zvakafanana uremu, vane nomumugwagwa kwaitora nguva mwero kufema.

How kufema shiri?

Shiri dzine nemhando nhatu dzakasiyana kufema midziyo. Ichi pamberi mhepo mabhegi, chiedza uye neshure mhepo muhomwe. Mumwedzi wokutanga inspiratory okisijeni inopfuura nomunyika wemhino panguva mhesano pakati rokumusoro chikamu muromo uye musoro. Hezvinoi neshungu, humidified uye yakasvinwa. Dzine zvinyama zvakavapoteredza, mune dzimwe mhando, akadana cere the. Kuerera ipapo chinoita kuti nasal mhango. Inhaled mhepo hakugumiri kumunda trachea, kana gurokuro, iyo rakakamurwa principales maviri. Uyezve, vari mapazi kuva muzvizhinji munzira imwe neimwe zvemapapu.

Vazhinji muviri rinenge anenge 1800 duku pedyo tertiary bronchus. Hunozoita kuti tuduku mhepo capillaries dziri akandipa neropa, apo kupanana magasi kunoitika. Mhepo kuyerera hazvipindi zvakananga mumapapu. Asi, anofanira kuva caudal SACS. A shoma muswe ichipfuura paumbwe kuburikidza principales, izvo zvinozoita akakamurwa zviduku dhayamita capillaries. Kana shiri inhales kechipiri, okisijeni iri akatamira kune cranial mhepo SACS, uye odzokera kuburikidza fistula kupinda trachea vachishandisa dokeriro. Uye pakupedzisira, kuburikidza nasal mhango uye anosiya wemhino.

kunzwisisa maitiro

The kufema Hurongwa rine shiri vachipiwa mumapapu. Vose vanoumba mumwe kunofambira mberi chivakwa pamusoro pemvura kuti gasi exchange. Wedzera uye kubata mhepo SACS chete, zvichiita okisijeni kufamba kuburikidza yakatarwa chiedza. Inhaled mhepo anoramba ari marongedzero maviri azere zvinogara isati wapera chose. Chii chikamu kufema ezvinhu shiri anokonzera gasi Exchange? Izvi basa rinokosha iri kuridzwa ne chiedza. The chiutsi mhepo ikoko ari kutanga kubuda mumuviri kuburikidza trachea. Mumwedzi wokutanga kufema chiutsi magasi zvakaitika munzvimbo pamberi mhepo mumasaga.

Havagoni chete kusiya muviri, sezvo ari wechipiri Kufema inotonhorera zvakare runoyerera kupinda zvose rwemberi mubhegi nemapapu. Zvadaro, panguva nedzinovengwa wokutanga rukova wechipiri inoyerera kunze kuburikidza trachea uye yakachena okisijeni kubva muhomwe anopinda kuti gasi mukutsinhana zveshure miviri. Structure shiri kufema ezvinhu ane chimiro iyo anobvumira nokuumba unidirectional (imwe-nzira) mhepo yakachena pamusoro pemvura gasi mukutsinhana kuitika mumapapu. Uyezve, kubuda ichi anoenda ikoko panguva zvose inhalation uye nedzinovengwa. Somugumisiro, exchange reokisijeni uye carbon dioxide rinoitwa dzose.

Kubudirira mugadziriro

Kunyanya kufema mamiriro shiri regai mukagamuchira okisijeni inodiwa masero omuviri. The guru anobatsirwei unidirectional uye Árbol marongerwo. Pano mhepo capillaries vane chikuru kunopindirana pamusoro nharaunda pane Somuenzaniso, mune mhuka. The makuru indekisi iri, zvikuru okisijeni uye carbon dioxide inogona kutenderedza muropa uye munyama, izvo chinopa zvimwe zvokufambisa kufema.

Marongerwo anatomi dzedenga SACS

The shiri ine nemhando mashomanana mhepo matangi, kusanganisira caudal abdominal uye caudal pectoral. Nemamiriro kuchibva cranial remuromo, clavicular uye cranial thoracal muhomwe. compression yavo kana nokuwedzera kunoitika apo muviri kuchinja, vari mairi iri. kukura mhango inotongwa tsandanyama kufamba. Kudeuka Kukwanisa dzedenga yaiva mukati abdominal rusvingo uye runopoteredza zvomukati, akaisa mukati mayo. In yezviri mamiriro Somuenzaniso panguva kutiza, shiri inoda zvakawanda oxygen. Kugona tsonyera uye kuwedzera muviri mhango haagoni chete kudzinga zvimwe mhepo kuburikidza mumapapu, asi kuderedza uremu minhenga chisikwa.

In mumhepo chokubuda anosika kutiza palpitations kufamba wamapapiro, nezvizere mhepo SACS. Abdominal tsandanyama zvikuru mhosva muitiro yozorora. The kufema maitiro shiri zvakasiyana tichitarisa zvayakaita uye vakuru kubva tinoberekwa mhuka. Shiri vane chiedza - diki, chiine, chirambe chakapfava mamiriro yakaumbwa pakati mbabvu kumativi ose nomuzongoza iri thoracal mhango. Gobvu zvinyama mitumbi izvi mapapiro vanoyera sekuda mhuka yakaenzana muviri uremu, asi kugara chete nehafu vhoriyamu. Healthy vanhu yemanyorero vane chiedza blue rakachenuruka.

kuimba

Mashandiro ari kufema ezvinhu shiri hakungoitwi kufema mumwe chete uye oxygenation masero omuviri. Zvinogonawo zvinosanganisira kuimba, izvo kudzora kutaurirana pakati pevanhu. Pembe - ndicho ruzha yakabereka Vocal nhengo riri mujinga trachea kukwirira. Sezvakaita pamwe dokeriro pamusoro mhuka, zviri zvinoberekwa vibration mhepo ruchiyerera napakati muviri. Ichi chinhu yaingowanikwa rinobvumira mamwe shiri kubudisa vocalizations zvikuru kunzwisisa, kuti vatevedzere mashoko evanhu. Dzimwe mhando vaimbi vanogona kubereka ruzha siyana dzakawanda.

nzendo kundosvikira

The inhaled mhepo runoyerera kuburikidza kufema kutenderera maviri. Anoendeswa pamwe chete, vari anoumbwa muzvikamu zvina. A dzakatevedzana matanho akawanda dyidzana kuti maximize matsva mhepo neVadzidzi kufema pechiso mumapapu. Zvichiitika sezvinotevera:

1. Most dzedenga inhaled rokutanga danho, ichipfuura mukuru principales kurutivi rwemberi mhepo vanekuva.
2. Inhaled okisijeni inofamba neshure mabhegi mumapapu. Pano gasi Exchange kunoitika.
3. Nguva inotevera kana shiri inhales, okisijeni-zvakapfumisa rukova inodedera pamberi zvemapapu vanokwanisa.
4. Second nedzinovengwa displaces mhepo vafumiswa pamwe carbon dioxide inobvisa nechemberi mumasaga kuburikidza principales uye trachea shure mumhepo.

High okisijeni chinodikanwa

Nokuda mukuru mwero muviri zvakakodzera yokutizira, pane nguva dzose refu kudiwa oxygen. Kuongorora zvose zvinotaurwa kufema wemuTesitamende shiri, tinogona kugumisa kuti zviri mudziyo kwayo ari kubatsira kusangana kudiwa ichi. Nepo shiri muri chiedza, ivo rinonyanya vanovimba dzedenga masaga kuti kufefetedza, izvo zvinoumba 15% of zvachose muviri vhoriyamu. Panguva iyoyowo, kwemasvingo avo havana chakanaka ropa wedzerai, saka regai kutamba zvakananga basa gasi exchange. Vanoita sevarevereri kufamba mhepo kuburikidza kufema hurongwa.

In mapapiro hapana diaphragm. Naizvozvo, pane nguva kuwedzera uye marwadzo ari kufema zvomukati, sezvakaita iri mhuka, zvinoshingaira danho iri shiri nedzinovengwa kuti inoda tsandanyama marwadzo. Pane pfungwa dzakasiyana-siyana pamusoro sei shiri kufema. Masayendisiti akawanda vachiri kudzidza kwacho. Zviri nemamiriro kufema ezvinhu shiri uye mhuka havasi zvakafanana nguva dzose. kusiyana izvi kubvumira hama dzedu mapapiro vane anodiwa adaptations yokutizira nokuimba. kwadzakabva Izvi zvakakodzerawo tichizvibata zvazvingava metabolic vose zvisikwa zvinobhururuka.
