Ziwiya wathanzi magazi: a moyo wopanda matenda a mtima

Magazi m'thupi akutumikira monga chinthu kulumikiza pa ntchito yofunika kwambiri ya m'selo iliyonse limba. kayendedwe ake mu thupi amatchedwa kufalitsidwa, imene mpweya, mahomoni ndi zakudya kudyetsedwa kwa zimakhala onse ndi ziwalo, ndipo kumeneko ndi thandizo la mankhwala linanena bungwe la kuwonongeka zinyalala zinthu. Komanso, magazi akuchita thermoregulation thupi, komanso amateteza izo kwa tizilomboto zoipa. Kupitiriza kupereka zipangizo magazi magazi ndi mtima amene amapanga ndi mitsempha ya magazi, onse amene ntchito ndi mosamalitsa mgwirizano.

Mitsempha akukhudzidwira amene amaphatikiza kutalika ndi 100 zikwi. Km, izo likulowerera thupi ngati ukonde chimphona, kulola yonse yochepetsetsa mpweya. magazi kumachitika mwachindunji kupyolera mitsempha, mitsempha ndi capillaries.

Mtsempha wamagazi - nkhungu-mipanda zipangizo kupereka magazi zimachokera mu mtima. Iwo kusintha kwambiri ndipo malingana ndi buku la kupopa magazi mtima kukuza kapena kuti mgwirizano. Mitsempha kunyamula magazi apindula ndi mpweya Mpweya, kuti ndi "oyera". Vienna, Mosiyana, kutulutsa magazi outflow wodzazidwa ndi mpweya. Malinga ndi iye magazi kulingalira mtima. Mtsempha makoma zochepa wandiweyani kuposa mitsempha ya. Capillaries ndi mitsempha zing'onozing'ono ndi khoma woonda kwambiri imene kubweranso kwa magazi mu maselo mpweya ndi zakudya ndi woipa ndimeyi mpweya ndi kuwombola katundu magazi mchipindamo.

Yaikulu (mu gawo mtanda ukufika 5 cm) magazi chotengera mu thupi - ndi msempha amene nthambi mu mitsempha, mitsempha - chifukwa arterioles (ziwiya zing'onozing'ono), ndi amene nawonso, pa capillaries lapansi.

The kutsogolera kwa kayendedwe ka magazi ndi kugunda. Kayendedwe ka magazi kumachitika mwa mabwalo awiri: wamng'ono (m'mapapo mwanga) ndi kufalitsa zokhudza zonse, mosalekeza otaya. Pamene ankayendetsa yaing'ono bwalo chachoka ku mpweya woipa ndi mpweya. Bwalo lalikulu M'malo mwake, amapereka amanyamula mpweya ndi chakudya, kutenga mpweya woipa komanso kuwononga katundu.

Mitsempha anthu kumathandiza kwambiri kwambiri m'thupi thupi. Iwo sali pachabe wotchedwa "mitsempha moyo": zingwe pamodzi pafupifupi maselo zonse za thupi, iwo kuonetsetsa ntchito yake ogwirizana.

Akatswiri a sayansi amanena kuti ziwiya magazi ukalamba ndi kuvala pang'ono pamaso pa mpumulo wa a thupi. Ndipo anthu akunyoza Baibulo limatchula nthawi ndiponso chimene kudya ndi kumwa, ngati si nawo mbali pa masewera, kuti zimene moyo wake mosalongosoka, mothamanga zinyalala kwachilengedwenso ndi poizoni osiyanasiyana amene waikamo pa Mitsempha. Slagging ziwiya kumabweretsa kuwonongeka kwa kotunga magazi kwa thupi lake, limene pamapeto amachititsa minofu chosowa zakudya zofunikira. Kotero tayamba matenda onse odziwika, ndi kuyambira pali ukalamba thupi.

Zamtima matenda pamodzi ndi shuga ndi khansa tsiku, mwamphamvu akugwira kanjedza mwa matenda owopsa ndipo ambiri. Mu gulu la matenda a zotengera mtima ndi magazi zotsatirazi:

- inatsekeratu matenda a mtima,

- enaake ophwanya matenda a mtima,

- matenda ziwiya oziziritsa magazi,

- kobadwa nako matenda a mtima ,

- m'mapapo mwanga embolism,

- thrombosis kwambiri mtsempha,

- zotumphukira wolumikizira matenda.

matenda pachimake monga sitiroko ndi matenda a mtima zimachitika makamaka chifukwa chotengera occlusion zoletsa kuti zina otaya magazi kwa ubongo kapena mtima. Chifukwa blockages - madipoziti mafuta pa makoma mkati Mitsempha kuti kupereka magazi kwa mtima kapena ubongo.

A vuto wapadera kupeza matenda ndi mtima mtima ndi asymptomatic, matenda awo kotero yake osati kuteteza ndi mavuto aakulu, koma nthawi zina - kupulumutsa miyoyo.
