Kuita mabasa ropa zvinogoneka nokuda inofamba rayo pamwe neropa mudziyo hurongwa. Aigovera mutinhimira sunga nomwoyo mabasa akafanana pombi. Kufambira kuburikidza midziyo ropa, ropa transports zvokudya, okisijeni uye carbon dioxide, kudzivirira muviri kurwisa utachiona, dzinovimbisa ari homeostasis pamusoro pezviri kwezvakatipoteredza.

For midziyo zvinosanganisira arteries, capillaries uye mutsinga. Ivo rinotsanangura ropa gwara mumuviri. Ndoupi musiyano pakati tsinga mutsinga? Zvinowanikwa mumuviri nemamiriro uye mabasa anoitwa. Ngationgororei navo zvizere.

The tsinga waisiyana mutsinga vakanga peculiarities ose

Arteries - nhumbi kuti zvinopa ropa kuyerera kubva pamoyo nyama uye nhengo dzomuviri. Kudeuka tsinga mumuviri anonzi rokuti "yeropa". Inouya zvakananga kubva pamwoyo. Munguva arteries ropa uchifamba pasi kumusoro kumanikidzwa. Kutsigira izvozvo, zvakakodzera mamiriro kwemasvingo. Zvinosanganisira matatu akaturikidzana. Yomukati dzokunze kuumbwa connective zvinyama uye svikiro - kuti tsandanyama fibers. Nokuda mamiriro ichi, midziyo iyi vanokwanisa ndichisveerera, uye nokudaro angakudzivisai cheBP.

The nemamiriro mutsinga kwakatosiyana nemamiriro arteries? Chekutanga nhumbi imwe mhando kutakura ropa kubva nhengo uye nyama mwoyo. Mushure achipfuura zvose masero uye zvomukati, izvozvo yakazara carbon dioxide, izvo zvinounza chiedza.

Mumwe mubvunzo unokosha - ndiwo musiyano pakati nemamiriro tsinga masvingo uye mutsinga. Ekupedzisira vane wakawondereiko kudai mazuva ose tsandanyama layer naizvozvo zvishoma kwakavharwa nenyama. Sezvo ropa runoyerera mutsinga pasi zvishomanana kumanikidzwa, stretchability ravo harina kufanana kukosha.

Kwakakura kweropa iri midziyo siyana kuratidza rakasiyana-siyana ropa. Kana arterial ropa nesimba yakabudisa pulsating tsime. It nezvitsvuku sezvo oxygenated. Asi pamwe venous - zvinoreva munhu anononoka karwizi, uye ane ruvara rima. Zvinonzi kunoyerwa yakawanda carbon dioxide.

Most tsinga lumen chinhu kushandiswa muhomwe mavharuvhu kuti kudzivirira ropa kufamba negwara risiri.

capillaries

Musiyano arteries kubva mutsinga, tinonzwisisa. Ngatifungei kuteerera duku tsinga - capillaries. Ivo akaumba munhu chaiye kuifukidza zvinyama mhando - endothelium. Voitakura kuburikidza muviri pakati interstitial mvura uye neropa. Nokuda kwaizvozvo pane chinoramba kupanana magasi.

Tsinga kusiya mwoyo, kuputsa kumusoro capillaries kuti zvakakodzera kuti musero rimwe nerimwe romuviri, kubatanidzwa nomumwe kupinda venules. The yokupedzisira, akavapindurawo, chokuita kuti midziyo kurei. Dzinonzi mutsinga, izvo zviri chikamu mwoyo. In kuramba ropa ichi capillaries kufamba basa rinokosha kuti yakananga kuonana pakati zvinhu ropa uye masero yose muviri.

Kufamba kweropa kuburikidza nhumbi

Musiyano arteries kubva mutsinga, uye chinoratidza mashandiro ropa kuyerera. Panguva marwadzo mwoyo tsandanyama nechisimba ropa kusingachakosheswi tsinga. Remasangano kwavari - yeropa, kumanikidza ungasvika mmHg 150. Art. The capillaries ari substantially wakaderedzwa kusvika padanho 20. The mukaha venous nevamwe zvishoma uye yaiva 3-8 mm HG. Art.

Chii matauriro uye BP?

Mune zvinoitika ezvinhu muviri nhumbi dzose dziri mune undervoltage ezvinhu - inzwi. Kana matauriro rwuchiwanzwa, midziyo ropa kutanga kuderedza. Izvi zvinotungamirira yakawedzera kuomesa. Kana ichi anova wakatsiga zvakakwana, pane mamiriro inonzi neBP. Harungashandurwi dzakareba decompression hadzichatori - hypotension. Vose zvirwere izvi kune ngozi chaizvo. Kutaura zvazviri mumutsetse wokutanga munhu vascular mamiriro kungaita kuti nokuvhiringidzirwa kuvimbika wayo, uye iri rechipiri - kuderera ropa wedzerai nhengo.

Achipfupikisa: dzakasiyana arteries ose mutsinga? Ichi kunyanya maumbirwo masvingo, pamberi mavharuvhu, iyo nzvimbo hama kuti mwoyo uye mabasa anoitwa.
