BP

BP - kumanikidzwa nenhumbi ropa. Pasina izvozvo, hazvibviri kupedza Implementation of metabolic pezvakaitwa ari nyama dzomuviri. Pamusana kwaari, ropa zvinofamba kuburikidza kweropa hurongwa.

BP zvinoumbwa mukati yakavharika, rirambe richibvira ukuwo - mune venous capillaries uye - ari mutsinga.

Uyezve, pane osmotic kumanikidzwa ropa, izvozvo zvinoenderana wevasungwa pakati chicherwa munyu. Its anokosha yemanyorero anoramba akatsiga. Asi kunyange munhu usingashandi kuchinja zvinogona kuparadza masero matsvuku eropa. For neurohumoral mutemo pakati osmotic kumanikidzwa basa ziya mumasero neitsvo.

Kutaura zvazviri, kuti guru zvichaitawo kuti arterial BP, chinobata:

- simba sunga mumoyo;

- uwandu ropa vabudiswa navo panguva imwe apo mumwe tevererana rutapudzo;

- the kurwisa iyo mudziyo masvingo (peripheral) nokupa ropa aibuda kuchienderera;

- nhamba heartbeats por chairema nguva kushandisa.

Secondary zvinhu achifurira BP - ndiyo nhamba uye viscosity. Uyewo, musiyano iri kumanikidzwa muna abdominal mhango uye thoracal mhango, izvo unovapo nokuda kufamba munguva afemeruke.

The kunonyanyisa BP zvinoitika kana kuderedzwa rworuboshwe ventricle (systole). Saka vabudiswa kwazviri panguva imwecheteyo inenge 70 ml ropa. Kuburikidza capillaries uye zvimwe zviduku midziyo mari yakadaro pakarepo havagoni kuwana kuburikidza. Yeropa, nokuda elasticity ayo, akatambanudza, panguva imwe chete anomutsa uye systolic BP. Muvanhu (utano) vanopfuura makore 16, zvinoita ingabva 110 kusvika 130 mm HG. Art.

Panguva diastole - the kumbomira pakati sunga ari kuruboshwe uye ventricles zvakanaka - the akatambanudza parusvingo guru arteries uye yeropa vanotanga shure. Saka, vakanga kusingachakosheswi ropa capillaries. Uye ayo kufurira anodonhedza pakuguma diastole mu yeropa iri akatura 90 mm HG. Art, uye makuru kadikidiki arteries -. 70 mm HG. Art. Musiyano systole uye diastole iri panoonekwa murume ari muchimiro kufamba kweropa.

The mukuru kure kubva ropa midziyo mwoyo, rezasi kumanikidza mairi. Chokutanga, yokumusoro nhamba inoratidza systolic kufurirwa uye yechipiri yakaderera - nokuti diastolic.

In hombe arteries riri kumusoro ari arterioles zviduku. In yezwi rirambe richibvira mubhedha BP kunodzikira, zvakawanda muwisira tsinga uye rinosvika kunyange kunaka tsika muchanza mutsinga.

Usaruyera zviri pamutemo haana nyore zvikuru mutsinga kana capillaries. Naizvozvo, munhu kumanikidza ukoshi haanzverwi pamusana pakutsunga yaro arteries.

Performance yaro anowanzoita pakuti sei munhu mupenyu, zvaanoita, ine nomumwe zvinhu. With zera, uwandu kufurirwa shanduko. Uye kunowedzera yakawedzera mupfungwa, mumuviri basa. Panguva iyoyowo, vatambi, vanhu vari kuramba kushanda zvakaoma miviri uye kunogona kuderera.

Systolic BP vana pakutsvaga nzira 80 + 2a, izvo pamwe - ndiro zera (mumakore).

The zvigadziriswe kuripo mumuviri uye kudzora padanho kufurirwa, kubvumira kuti kudzokera zvakajairika pashure zviduku nokufamba somugumisiro mupfungwa kana mumuviri basa.

Kana vari kuputswa, pane kuramba shanduko ayo zvichikwira, ipapo kutaura pamusoro neBP, kana pasi, zvino anouya hypotension.

Kazhinji, munhu anoziva ropa ravo kumanikidzwa kuita kwomuzvarirwo. Uye chero kutsaudzira mu kana mirayiridzo ngaive chikonzero kuenda kwachiremba nokuti zvikonzero kuti anokonzera ichi chinoratidza yakatarwa. Somuenzaniso, mune zvirwere zvinotapuriranwa, mwoyo, kana nomuchetura rinowanzoberekera hypotension. Uye pamwechete itsvo zvirwere, kwemakemikari anobudiswa nenyonganiso - neBP.
