Kufamba kweropa kuburikidza nhumbi. The mashandiro uye mitemo ropa kutenderera

Kuramba mutinhimira marwadzo mwoyo tsandanyama achibvumira ropa yokukunda kurwisa kuti anosika arambe achirema rwengarava ropa akabatana warwo viscosity. A BP musiyano achiumbwa uye vakaramba migove venous uye arterial pamusoro kweropa hurongwa. The inotungamirwa munhu musiyano hwakadaro panowanikwa nzvimbo yakakwirira uye vakaderera nevamwe imwe huru zvigadziriswe nawo pane ropa riyerere kuburikidza nhumbi.

BP

Kushanda mwoyo kunogona kufananidzwa mhando pombi kushanda. Mumwe mutinhimira marwadzo mwoyo ventricles kunotungamirira nokubudiswa kupinda vascular hurongwa inotevera chikamu oxygenated ropa, zvichikonzera dzidzo BP.

Mukuru pamwero dzvinyiriro rakasiyana kufamba kweropa iri yeropa, uye yakadereresa - iri mutsinga hombe dhayamita. Panguva kubviswa cardiac tsandanyama pane kuderera BP, uyewo tava kuderera kufamba kweropa kuburikidza nhumbi ropa.

ejection ropa munzvimbo arteries unowanikwa batch. Pasinei neizvi, muviri nguva akaona ropa aibuda kuramba. The tsanangudzo iyi yakakwirira elasticity ari mudziyo masvingo. On kubvuma mupfumi ropa kubva mumwoyo tsandanyama rusvingo midziyo wakauya rwakatambanudzwa ezvinhu uye, nokuda elasticity, nokusika zvinhu nokuti kutamira ropa kurutivi midziyo diki.

The mashandiro ropa riyerere kuburikidza midziyo inobva kunonyanyisa kufurira kunoitika panguva iyo marwadzo ose cardiac ventricles. Minimum kumanikidzwa ari kuchengetwa panguva kuzvivaraidza mwoyo tsandanyama. Kusiyana kufadza uye shoma BP rinorondedzerwa so kufamba kweropa kufurirwa. Ndizvo waivako yakasimba kupomba nevezera chinoratidza kuti mwoyo kushanda zvakanaka.

kufamba kweropa

Dzimwe nzvimbo dzomuviri womunhu palpation ganda unokubvumira nekusangana mutinhimira kufamba kweropa kuburikidza nhumbi. Fani iyi zvinonzi kupomba, iyo yakavakirwa kwenguva nenguva chiwedzerwa jerky arterial rusvingo pasi pokudzora cardiac pulses.

Zvichienderana nokuwanda kupomba anorova zvinogona nokutongerwa imwe nguva, kuti zvakanaka kuti mwoyo tsandanyama kutsungirira basa nayo. Vanonzwa kufamba kweropa kuburikidza nhumbi, kwemwoyo, iwe unogona, kudzvanya kubudikidza ganda rimwe chikuru arteries kuti mafupa.

Movement ropa kuburikidza mutsinga

Kufamba ropa ari mutsinga ari mhango ine peculiarities ayo. Kusiyana tsinga, muduku kusanduka venous rusvingo akasiyana zvishoma gobvu uye nyoro unaku. Somugumisiro, ropa kutamira kuburikidza mutsinga maduku unoitisa zvishoma kumanikidzwa, asi guru dhayamita mutsinga hauoneki zvachose, kana kunyange kuenzana razero zviratidzo. Saka, ropa kutamira kuburikidza venous makwara kuti mwoyo zvinoda kukurira pachako giravhiti kwayo uye viscosity.

A inokosha mukuita kutsiga ropa kuyerera venous anoita chishongedzo tsandanyama marwadzo, rinova avepo riparadzirwe. Marwadzo ose tsandanyama kunotungamirira compression pamusoro mutsinga izere neropa, zvichikonzera kufamba kwayo kurutivi mwoyo.

vascular matauriro

The nemamiriro vascular masvingo, kunze capillaries diki, inobva kumeso tsandanyama, izvo pasi zvinoderedza kunyange kusavapo humoral kana Neural zvinhu. Fani iyi inonzi basal tonus pamusoro vascular madziro. Uye inobva aikanganiswa ari zvinyama stretchability, zvemaziso Kufurirwa nevamwe mufambo nhengo, kwetsandanyama.

Basal mataurire pamwe mwoyo urove ndiye anokonzera kufamba kweropa kuburikidza nhumbi. Kwakunoitwa nedanho basal Matauriro nenzira dzakasiyana-siyana kuti kuitisa ropa hakusi chete. Kwakavakirwa anotsvedzerera tsandanyama marwadzo ari epithelium, uyewo ezvinhu izvo zvinosimudzira paumbwe vascular lumen, apo kuramba BP, kupa ropa wedzerai nhengo.

Mwero ropa riyerere kuburikidza midziyo

Mwero ropa kuyerera vascular ndiyo nechiidzo inokosha nechirwere wokufambisa. Yakadereresa kumhanya ropa kufamba riri kuchengetwa ari rirambe richibvira network, uye-soro - iri yeropa. Action kuti muenzaniso uyu anotakura nayo inokosha zvoutachiona pfungwa, sezvo anonoke kufamba reokisijeni-vapfumi ropa uye zvinovaka muviri zvinhu kubatsira avo pfungwa kuparadzira mune nyama uye nhengo dzomuviri.

Blood kuyerera velocity

Kusiyanisa Linear uye volumetric ropa riyerere unodiwa. Akaverenga indekisi Linear ropa riyerere velocity kwakavakirwa kutsunga Chikamu vascular ino yose muchinjikwa. chikamu muchinjikwa vanosvika pamusoro uwandu hwezvinhu zvose zvabatanidzwa. rirambe richibvira richikurukura Muviri womunhu kakawanda kupfuura lumen of thinnest mudziyo - yeropa, uko Linear velocity zvasvika pamwero kunonyanyisa.

Kufungisisa chokwadi kuti mumwe tsinga nokuti mutsinga anopfuura maviri ari mumuviri womunhu, hazvishamisi kuti yose lumen venous nzira kanoverengeka kupfuura arterial. Izvi zvinozoita kunotungamirira vasanyanye venous ropa riyerere velocity kubudikidza vanenge hafu. Linear nokukurumidza zviratidzi mhango mutsinga vakaenzana masendimita anenge 25 / Maminitsi uye kashoma kupfuura kukosha ichi.

Volumetric kuyerera velocity

Kutsunga ropa vhoriyamu misha nokukurumidza inobva dzaona yaipedzerwa kana kuita zvedenderedzwa kuburikidza vascular ezvinhu pamusoro chairema nguva. Muchiitiko chino, inobviswa hunokonzera kufamba kweropa kuburikidza nhumbi, sezvo paine nzira conductive nguva dzose inopfuura zvakaenzana ropa muzana chikwata nguva.

The kupera nguva redunhu ndiyo nguva iro ropa rine nguva kuenda kuburikidza zviduku kufamba kweropa. Kana utano mwoyo kushanda uye kuvapo vanenge 70-80 anorova paminiti izere kufamba kweropa kuburikidza nhumbi pamwe okuguma redunhu kunoitika anenge 22-23 seconds.

Zvinhu kuita kuti ropa riyerere vanoshingaira

Pakusarudza, t. E. The koshesa chinhu inopa nomazviri kufamba kweropa kuburikidza nhumbi, ndiro basa pomwoyo. Zvisinei, pane zvakawanda zvakafanana kuchikosha inonzi upiyona aibuda zvinhu, ramakagadzwa zvinofanira pachena:

• namahwindo zvakaita vascular hurongwa;
• Sarudza zviratidzi kumanikidzwa kusiyana muchanza tsinga, yeropa nemidziyo;
• elasticity, iyo elasticity mudziyo masvingo;
• kushanda mwoyo vharuvhu mudziyo kuti anopa ropa kufamba chete divi;
• kuvapo tsandanyama, nhengo, intrathoracic kumanikidzwa;
• kufema basa, zvinoita kuti kubvisa ropa chokupfeka.

Training of kumwoyo

Healthy mutemo ropa riyerere kuburikidza midziyo zvinogoneka chete kutarisirwa mwoyo wake kurovedza. Munguva muchinjikwa-kudzidzisa vanoda kuti zvinyama oxygenation inowedzera yekudyidzana. Somugumisiro, kuti nechokwadi upenyu muviri mwoyo une kupomba zvikuru ropa pane pamwe muviri nokuva ezvinhu zororo.

Vanhu vane basa, anenge immobile mararamiro, zvikuru zvikonzero kufamba kweropa kuburikidza nhumbi - izvi chete rokumuka kwemwoyo. Zvisinei, nguva dzose ari pasi kunetseka, pasina activation kuti ebetsero zvinhu ropa kuyerera, mwoyo tsandanyama iri zvishoma nezvishoma kutanga kupera. Izvi Muitiro kunotungamirira mwoyo kuneta sezvo kusimbisa ropa wedzerai nyama uye nhengo kunoitika pfupi, pfupi. Pakupedzisira, kushaya basa rose nomuviri, zvainanga kutamira ropa, inoenda anyatsoona Kushatiswa mwoyo.

Kurovedzwa zvinofamba vanhu vasiri mutorwa kune dzose kurovedza muviri, kana zvemitambo kana mabasa nokuda kwebasa, vane mwoyo utano hwakasimba. Kurovedzwa pomwoyo anokwanisa kupa yakatsiga ropa makopi pasina kuneta kwenguva yakareba. Naizvozvo, kushingaira pafoni mararamiro, musoro pfungwa alternation rokuzorora uye muviri kubatsira kusimbisa mwoyo uye kumwoyo yose.
