Mhedziso

Mhepo inopinda mumuviri kuburikidza nemuromo kana mumhino uye nekukurumidza inoenda kune iyo pharynx, kana huro. Kubva ipapo, inopfuura nepaburi, kana izwi bhokisi, uye inopinda mutrachea.

Iyo trachea ipombi yakasimba iyo ine zvindori zvecartilage iyo inodzivirira iyo kuti isadonhe.

Mukati memapapu, matavi etrachea kupinda kuruboshwe uye kurudyi bronchus. Izvi zvinowedzera kupatsanuka kuita zvidiki uye zvidiki matavi anonzi bronchioles.

Iwo madiki bronchioles anopera mune madiki mweya masaga. Aya anonzi alveoli. Ivo vanofutisa kana munhu achifema uye achidzikisa kana munhu achinge afema.

Munguva yekutsinhana kwegesi okisijeni inofamba kubva mumapapu ichienda muropa. Panguva imwechete carbon dioxide inopfuura kubva muropa ichienda mumapapu.Izvi zvinoitika mumapapu pakati pealveoli uye netiweki yetsinga dzeropa dzinonzi capillaries, idzo dziri mumadziro ealveoli.

Pano unoona masero matsvuku eropa achifamba kuburikidza nema capillaries. Madziro ealveoli anogovera membrane neiyo capillaries. Ndo kuswedera kwavanoita.

Izvi zvinoita kuti okisijeni uye kabhoni dhayokisaidhi ipararire, kana kufamba zvakasununguka, pakati penzira yekufema neropa.

Maoxygen mamorekuru anonamira kumasero matsvuku eropa, ayo anodzokera kumashure kumoyo. Panguva imwecheteyo, mamorekuru ecarbon dioxide mune alveoli anopepereswa kunze kwemuviri nguva inotevera munhu paanofema.

Kuchinjana gasi kunotendera muviri kuti uzadze oxygen uye kubvisa kabhoni dhayokisaidhi. Kuita zvese zvinodiwa kuti urarame.
