Kweropa maitiro

Ezvinhu chero muviri mhuka ine boka kweropa zvomukati, izvo zvinobatanidzwa muropa riparadzirwe. Somugumisiro zvarakanga kushanda iri akatamisira rworudyi okisijeni uye zvinovaka muviri, hormone munyu uyewo zvimwe zvinokosha zvinhu. Mukuwedzera, kufamba kweropa hurongwa anoita basa rechipiri. Zvinotora masero uye dongo Exchange zvinotora kubva mumativi ose muviri aumba mairi carbon dioxide. A kunzwisisa samambure umo zvakakodzera kushanda muviri zvinhu zvakakumikidzwa munyika yose ezvinhu ayo, aumba kubva midziyo, mwoyo uye neropa pacharo.

System oparesheni, kupa nhengo zvose zvinovaka muviri, kwakavakirwa basa myocardial tsandanyama. Ndiko, kuita mashandiro pombi, kupomba ropa panguva kumhanya. Kukosha ichi uwandu akaenzana mamita ane gumi nerimwe chete wechipiri. Apo sunga komoyo tsandanyama mu Urume kumanikidzwa kunoitika, izvozvo inonzi kunyanyisa. Zviri pamusoro ratinoona. Kunwisa kushushikana mune okurapa inonzi ropa. chipimo Its chinotanga kutaridza razero ukoshi vakaenzana kukura kusvika mumhepo kumanikidzwa. Mukati miniti rimwe basa rinoitwa munguva quiescent mamiriro womuviri, mwoyo pumps kuburikidza pacharo substantially 3,6 litres ropa kuti tirambe dzomunyika voltage ikabereka. BP anotora kunonyanyisa kukosha kwayo panguva bumbiro remitemo iri rutapudzo (systole). Kana myocardial kutandara (diastole), dzomunyika voltage anodonhedza kuti Zero.

The kweropa maitiro samambure wayo transmits ropa riyerere. Nepano midziyo, Pakusuma mvura ane arambe achirema pamusoro 1,06 magiramu muzana cubic sendimita. Blood kuyerera anozunungusa kuburikidza hurongwa, kusanganisira arteries uye mutsinga makuru. Izvi midziyo bazi kakawanda uye zvishoma nezvishoma kuderera kukura nemaduku capillaries. Ropa kuyerera zvinofamba panguva kumhanya iyo inopiwa mwoyo mutinhimira. On kufamba nemvura Kunochinjawo dzomunyika kunetsana uye dhayamita mudziyo lumen. Arteries Apfuura kuburikidza neropa rukova pa makumi mashanu masendimita por wechipiri. Mune mutsinga ukoshi hwayo iri makumi maviri masendimita / s. The capillaries ndivo kupfuura yakaderera nokukurumidza nokuda kwavo dhayamita duku. Zviri millimeters por wechipiri asingasviki maviri. Kana ichi kumanikidzwa pulses vari woutsinye mu capillaries.

Bhuku kweropa hurongwa chikuru zvikuru kupfuura mari muropa muviri. Rakazara chete makumi mana namazana. In ichi pane chikonzero. Kana mamiriro ezvinhu simuka kuti zvinoda zvakawanda ropa riyerere kuti nhengo, zvichaita kufamba mugwara.

Anatomy kwemwoyo uye ropa midziyo nguva Dzinogara anobvumira ropa iri Triangle, rinosanganisira mapapu, tsandanyama, myocardium uye chiropa. Panyaya iyi, anodiwa zvokudya achipfuura arteries uye capillaries, uye kuwana musero rose muviri womunhu, inobatsira kuti chakaipa nokushanda kwenhengo dzomuviri. Kana achiumba cardiac tsandanyama uye vascular pathological mananara kuitika kweropa zvirwere. zvirwere izvi zvinosanganisira:

- chenjera rheumatic fivhiri mhando;

- ischemic chirwere mwoyo mhasuro;

- nezvirwere izvo pamwe kuwedzera BP;

- rheumatic chisingaperi mwoyo chirwere;

- kutyora pulmonary riparadzirwe ropa;

- cerebrovascular chirwere;

- chirwere of capillaries uye arteries;

- zvirwere mutsinga, nhengo dzinobudisa midziyo uye nodes;

- vamwe midziyo uye mwoyo chirwere.

Kweropa ezvinhu, uyewo utano hwake hwakada akatarira nesayenzi yezvokurapa. Chikonzero ichi ndivo vanoshorwa Statistical umboo kuti akaisa mwoyo uye vascular chirwere pakutanga munyika tichitarisa huno.
