The ropa mumuviri womunhu anoita akawanda anoitwa, inotidzivirira, anotakura zvokudya uye okisijeni kuti munyama, uye anoita kuti carbon dioxide. Inonzi arterial ropa rine okisijeni, uyewo anotakura zita oxygenated. Accession zvokuti zvakafanira gasi muviri rinouya erythrocytes, ane ari Morekuru chairo mapuroteni, heme, izvo zvinosanganisira simbi. Anatomy iri vakaratidza kuti arterial ropa riyerere ari arteries, uye ipapo, nokupa okisijeni, zvinova venous, uye runoyerera kuburikidza mutsinga.
Arteries uye rutina Zvavo
Arteries vanonzi midziyo iyo arterial ropa riyerere. Uye vari naye chete kubva pamwoyo. The Kudeuka womunhu mudziyo muviri, sezvamakaropafadzwa ropa inoyerera, akapfuma okisijeni, ndiyo yeropa utano akura hwevanhu, ayo dhayamita iri 2.5 masendimita. Arterioles vanogona kusvika 0.1 chete millimeter. Zvakananga pedyo bazi yeropa kwomwoyo nezvi- kwakavharwa nenyama fibers, ivo kunyevenutsa kupomba chinozunguzirwa yaunopiwa mwoyo uye arterial ropa ipapo runoyerera zvakaenzana kuburikidza nhumbi. Nenzira iyi, okisijeni iri zvishoma nezvishoma tinoshandurirwa jira. Next, ngarava masvingo hazvina sezvo raichinja-chinja uye kuwana mukuru arambe achirema, zvikurukuru nokuda pamberi tsandanyama fibers. Tsinga chokuita nedzimwe arteries, kunonzi collaterals, nokuda clogging navo mumwe mudziyo ropa anogona kuenda mumwe. Mumwe nhengo yomuviri inongogara tichimirira okisijeni, izvo saka zvakafanira muna dzinotsanagura simba muviri. The chikuru kushanda arteries ndiro chokuendesa ropa kwavari nokukurumidza sezvinobvira. In erythrocytes okisijeni zvikuru, saka ruvara arterial ropa - piriviri, ukuwo unocheka midziyo ine tsime, kupfuura zvose, nokuda kwokudzvinyirira kuti ariko mavari.
Anenge asingaoneki, asi zvinokosha
All chisungo kuchinjirwa okisijeni kupinda zvinyama rinoitwa munyika capillaries ndiyo yakanakisisa midziyo apo okisijeni uye carbon dioxide exchange. Kana muviri wakanaka, asi capillaries haichaonekwi, uye zvokurwara zvinogona kuonekwa rirambe richibvira reticulum. Rirambe richibvira kureba asina kupfuura millimeter, uye ayo Clearance zvokuti chete kunoita imwe erythrocyte. Mumuviri akawandisa midziyo yakadai, dzinonzi rirambe richibvira Network.
Chii chinoitika kuti okisijeni munyama?
Mumuviri, okisijeni rinobatanidzwa zvikurukuru mune mitochondrial oxidation kwendangariro. Panguva ino pane kuchinja Organic zvinhu, uye somugumisiro, simba rinobudiswa unonzi ATP (adenosine triphosphate), fuma iri zvakasikwa chete simba kunobva. Carbon dioxide, iyo yakaumbwa panguva muviri munyama, achipinda ropa, zvichiita venous. ropa ichi runoyerera napakati mutsinga, uye kupinda mumapapu, carbon dioxide rinobviswa muviri zvakatipoteredza.
Arterial uye venous
Zvechokwadi havagoni kutaura kuti arteries rimwe arterial ropa kuyerera, uye ari mutsinga - venous. Zvirokwazvo arteries kutakura ropa kubva mumwoyo, arterial. Asi ichi ndicho chete pachinhu hombe denderedzwa ropa kuparadzirwa, asi mune diki chokwadi. The pulmonary mutsinga runoyerera ari arterial ropa. Sei ari mutsinga? Zviri nyore chaizvo, nokuti mutsinga - midziyo kuti takura ropa pamwoyo, asi arteries - kubva kwaari. The arteries of pulmonary ropa riyerere venous.
gasi sezvamunoita
Kuti tinzwisise sei kuita mabasa avo nyore, uye okisijeni ine arterial ropa gasi sezvamunoita kutsunga rinoitwa. Chokukomborerwa asidhi-chawo pachiyero ichapa mamwe mashoko kuti zvicharatidza zvakavanzika itsvo kushanda kana kuvapo mumuviri chirwere. Analysis negasi sezvamunoita ambotirega zvakakwana uye zvinobudirira kunhonga okisijeni kana yakachena mishonga.
Vasati pachisara
Usati kuona gasi Zvinoumba ropa romunhu, zvakafanira kuti aedze Allen. Achakubatsira kuti unzwisise zvinorehwa dzichipfekeka mamiriro panguva yacho kweropa hurongwa. Musimboti zviri nyore chaizvo uye kunoratidzwa ndechokuti bvunzo zvakafanira abate pasi ulnar kana TOUR tsinga, iri chiningoningo. Ita izvozvo sokuvapo ruoko, kana panzvimbo rwake, hauzoti zvacheneruka. Next ngaarege midziyo, ropa aibuda anomutswa, uye muchindwi inofanira Pink kana Red hapana kupfuura kwemasekonzi mashanu. Uyezve zviri nyore kuona gasi nziyo, ropa ichi hunobviswa tsinga. The dhigirii reokisijeni saturation kuti Chizenga kunobva muviri tembiricha, asidhi-nechigadziko mwero, ari kukwana kumanikidzwa carbon dioxide. Kana ari kukwana kumanikidzwa anodonhedza pazasi 60 mm HG, zvinokwanisika kutonga kuderera okisijeni saturation pamusoro erythrocytes. Pashure paizvozvo unofanira kuita kumisa ropa kuti zvakasimba chakatsindirwa shinda iyi kana bhandeji, iyo chinobviswa hapana yapfuura pane maminitsi 30-60.
