Respiratoria uye gasi mukutsinhana: hwaro yeupenyu

Tichishandisa yapfuura, chete nzira yokuziva kana munhu mupenyu, zvave zvichibvira kuti rione kana kwete kuona zviratidzo kufema. Muromo tireyi uye girazi akatarira kana zvava Cloudy. Munguva yedu kushandiswa uye nezvimwe zvinhu, asi kushaya mweya nguva dzose anotaura kufambira kutsakatika kana kuti ndatoitwa kumira upenyu. Respiratoria uye gasi Exchange vachiri nemasayendisiti kunyatsonzwisisa basa ari kufema ezvinhu yose. Iro rakavimbika zvikuru, asi dzimwe nguva yava vanoshupika chaizvo.

ino zvinosanganisira Airways, nemamiriro ari kufema hurongwa rakafanana nzvimbo. Izvi zvinosanganisira kuti nasal mhango, dokeriro, trachea uye principales. All kwemiviri izvi vane shwashwa chizvaro, saka kuti vane chimiro chavo, asi mukati vari mudungwe pamwe ciliated epithelium mhando. It anokwanisa nzira dzisinganyatsooneki sunga rokudzinga duku vatorwa miviri kubva yemweya.

Zvisinei, chikuru kufema hurongwa, mapapu, anobatsira zvikuru kunzwisisa basa. Zviri pano kuti pane wekurukurirano pakati vakutarisire ropa uye mhepo uye. Respiratoria uye gasi Exchange, basa ravo guru zvine chokuita. Nyore kujairana nokuti basa iri kusimba.

Vakawanda vedu vaduku, kumanikidzwa kufema chete kuburikidza mhino. Nei zvichikosha ichi? On munzira nomumhepo hunowedzera nyorovera ari nasal mhango, asi zvimwe mhepo yakaoma aigona kukuvadza mumapapu (rangarira manzwiro angu pashure zvakare zvikuru run avhareji prodolozhitelnosti kana uine kufema achishandisa muromo). Uyewo, nasal mhango iri kunonoka guruva, asi zvimwe kunyange vechiduku mumapapu akafanana muguruva nemuteresi. Naizvozvo, avo muromo fema nguva, vanorwara kakawanda uye kukosora kunyange utano background.

Nasal mhango yakakamurwa kuva partition migove miviri, zvinonzi kuna nasopharynx inokosha makomba. The mhino rine olfactory nhengo uyewo nhengo, muchinzwisisa mapheromone - zvinhu kuti tive kukwezva vasikana. Saka kuti kufema uye gasi Exchange mupiro, uye ane zvinoumba dzimwe gadziriro.

Kubva nasopharynx nomumhepo zvinopinda mumuromo kusvika dokeriro, izvo anofanira nomunyika huro. Muna pharynx - rudzi yokuchinja kufema uye zvomudumbu nehurongwa. Pane akatendeka muchengeti - the epiglottis kuti kunotadzisa zvokudya uye mvura kuti inhaled. Zviri zvishoma pazasi pahuro zvinokonzera - inokosha kwakavharwa nenyama fibers, izvo emit varurame sezvaiitwa gitare.

Dokeriro chinosvika pasi mutsipa, apo rakatevera Danho iri nzira mhepo - trachea. Chii dzinonakidza, makore 16 trachea chinosanganisira shwashwa, asi gare gare - ossified. Kunyange zvazvo muviri ichi rakanyatsojeka anonzwisisa pakati nedanho afemeruke zvinosiyana pakureba uye dhayamita. Panoperera ari trachea rinotsemuka kupinda principales maviri. Ivo Bazi panze uye kupinda mumapapu, uye nzvimbo paanowanikwa izvi hazvisi kuoneka kubva kunze.

Mapapu vari zvakazara kwete apo isu vakajaira vazondifungira kuvapo kwavo - ari mubhokisi, ivo mutemo masendimita mashomanana pamusoro clavicle. goko yavo muzvikamu zviviri, pakati iyo pane mafuta, saka chiedza kunogona zvakaoma chaizvo uye kukweshera isina (romuzvarirwo) kuchinja chimiro chayo.

The principales bazi kunze bronchioles, uye ipapo uende matema diki - the Formação de.

Panguva kufema nyarara muzana 70 chete dzedenga kunosvika mumapapu. Nokuda musiyano iri kwokudzvinyirira kwomunhu okisijeni zvinoenda ropa capillaries Entangling Formação de, uye carbon dioxide, kusiyana, anobuda capillaries uye Formação de adzingwa.

Zvinokosha kuti iwe une utano kufema hurongwa. Zvino zvichava shasha gasi exchange. Izvi ichapa mukuru Kushanda uye mufaro. Dzivirirai mapapu ako kubva pauduku. Handiti ose zuva yavanobata kwatiri basa rakaoma uye kubvumira masero ose muviri anogamuchira anodiwa okisijeni upenyu.
