The zokhudza zonse makope - ndi zomangamanga chaluso

Kodi mukuganiza nyumba yomwe ndi zovuta piping dongosolo wodzazidwa ndi madzi kwambiri wapatali bwino yonyamula madzi, chakudya, mpweya ndipo amachotsa yopasuka? Komanso, mapaipi okha amatha okha kuti achire ndi kukula, kusinthasintha kwa kusintha mu nyumba. nyumba imeneyi zomangamanga chifukwa kusirira aliyense.

Koma wathu mitsempha ya magazi chingathe kwambiri. Ndi nthawi thupi kutentha, kusuntha nambala yaikulu mahomoni zosiyanasiyana zomwe timanyamula mauthenga zofunika kuti maselo onse, bungwe chitetezo tizilombo toyambitsa matenda. zopezera Ichi ndi kusintha kwathunthu ndi zofewa, choncho akhoza kuyamwa zodabwitsa zonse ndi idzakungana ndi thupi. Tiyeni tione ichi mwaluso pafupi.

Kapangidwe ka dongosolo anthu magazi

Pakati pa m'thupi thupi dzenje - mtima, womwe uli ngati mpope mosalekeza mapampu magazi mu kuzungulira chatsekedwa, wopangidwa mwa ziwiya.

Dongosolo lonse lagawidwa m'zigawo ziwiri:

• amayendera m'mapapo. dongosolo mtima yolumikiza pamodzi mtima ndi mapapo. Ayamba bwalo la ventricle Chabwino, mapeto a yankholo mu atrium kumanzere. Agwiritsidwa yekha m'mapapo.

• A bwalo lalikulu la magazi. Iwo anachokera mu msempha ndipo itha atrium bwino.

Large kufalitsidwa kwa ziwiya zake monga ambiri thupi lonse.

Mtima mothandizidwa ndi makoma kotenga lagawidwa pawiri. Aliyense wa mbali zimenezi anagawa mu amachepetsa awiri mwa partitions yopingasa, kupanga ventricle ndi atrium.

Magazi woyamba akulowa chotengera yaikulu ya thupi - ndi msempha. msempha Komanso lagawidwa ziwiya zing'onozing'ono, ndi mwazi akulowa mtsempha wamagazi wa kufalitsa zokhudza zonse. Pang'onopang'ono mitsempha nthambi kuchoka muyende mu arterioles ndi capillaries. The awiri a capillaries ndi otsika kwambiri - pafupifupi 10 microns. Izi zikutanthauza kuti maselo ofiira, amanyamula mpweya maselo kudutsa capillaries pa nthawi. Makoma a zotengera capillary ndi zoonda - zigwirizana okha wosanjikiza umodzi maselo, koma samaletsa mwa kundipatsako kwa zakudya zimakhala ndi ili mu gawo madzi a magazi (madzi a m'magazi). Imodzi minofu mu capillaries opatsirana wa carbon dioxide ndi kagayidwe kachakudya mankhwala omwe amafunika kuchotsa thupi.

The capillaries ndi pang'ono loopy minofu, njira imene iwo angathe kulamulira otaya magazi kudutsa iwo, kukakomana ndi zofuna za zimakhala ozungulira. Pamene mwazi umatuluka capillaries, Lifikira mitsempha tosaoneka - venules. Venules zina coalesce mu mitsempha, magazi pa iwo akupitiriza akudalitsidwa kufalitsa zokhudza zonse, kubwerera ku mtima. Mu mitsempha ya magazi ndi poyerekeza mitsempha, koma lumens ya mitsempha kwambiri.

Kodi kayendedwe achepe anaonetsetsa?

Zikomo ku anatengera wanzeru:

• Chikho woboola pakati mavavu kuti kuteteza magazi unaturuka pa mtima mchikakamizo yokoka.

• Ntchito ya minofu chigoba, amene compress mitsempha kwambiri spaced kukana magazi kudzera mavavu njira ya mbali ya mtima.

• Thupinso mu chifuwa ndi pamimba pa kupuma ndi zimasiyanasiyana amathandiza mitsempha kutulutsa magazi mu atrium bwino.

Pamene mavavu venous chilichonse zifukwa (mimba, kumtundu majini chingawapangitse kukhala zidakwa, kunenepa kapena mtunda wautali) sizili bwino, mwazi anasonkhanitsa, ndi mitsempha pathupi pansi mavavu lapansi. chikhalidwe Ichi chikudziwika ngati mitsempha varicose.

Kufalitsa zokhudza zonse akukamba mpweya ndi ubongo maselo. Choncho, kufalitsa ubongo magazi ikuchitika mwa malamulo omwewo monga ziwalo zina zonse. Ngati outflow venous kwa ziwiya ubongo ndi zovuta, ndiye pali chizungulire ndi mutu.

N'zosadabwitsa kuti dzuwa la dongosolo anthu magazi ili kwambiri moti ngakhale pa mpumulo kwa miniti imodzi, pafupifupi 5 malita a magazi umadutsa mtima ndi mpikisano wa za 35 malita miniti iliyonse.

Monga mukuonera Mlengi wathu kwenikweni kwambiri mlengi, amene choncho ndi dzanja - kufalitsa zokhudza zonse - ndi chidwi!
