Yevanhu mwoyo anatomi

Anatomy uye physiology kwemoyo vagara kukwezvwa vatsvakurudzi. Izvi zvinonzwisisika, nokuti mwoyo - ndiro chete muviri anoshanda autonomously. Kubva basa rake kunobva mukuru ezvinhu muviri, utano uye chirwere. Kutaura zvazviri, pamwe urove muviri wokutanga, upenyu hwevanhu rinotanga rokupedzisira kava nawo anomira.

mwoyo yevanhu anatomi rakanyatsojeka kunzwisisa - muviri anoita basa guru, kupa muviri wose neropa. Externally, mwoyo une chimiro cône, negomba mukati uye vakamiswa pamwe musculo-fibrous rukoko. Nheyo kushanda kwomwoyo vagara vandifungira ayo mamiriro. Afanane maviri mudariro pombi: wokutanga Danho iri ventricle, iyo pumps ropa mukati atrium, uye wechipiri Danho - atrium pumps ropa mukati yeropa. Zvingangoitika kupomba ropa inowanika kuburikidza atrioventricular septum - kuti zvinoshanda uye pisitoni, uye vharafu.

Anatomy womwoyo, pasinei ramakanzi bhuku canons zvachose nomumwe. Kunyange wawo, rinogona anosiyana zvichienderana zvinhu zvakawanda. Zvayaiva mwoyo zvakare kwete chete - nokuti vanhu vakawanda izvozvo akasiiwa ane zvaizopedza kusvika nepakati, uye mune dzimwe zviri zvava nepakati, uye kunyange iya kurudyi. Gogonera mwoyo uye arşive parameters - kakawanda unoratidzwa kumusoro uye kujekesa nechepasi, asi nhamba nhamba idzi dzose dzakasiyana-siyana (zvikurukuru kunoenderana mhando bumbiro). Mwoyo gobvu Paavhareji neeSultan kubva maviri namakumi mashanu mazana matatu namakumi matatu magiramu.

Anatomy mwoyo, sezvo vazhinji kunzwisisa nhengo zvakakwana kudzidza kufambidzana. Mwoyo une bhegi mwoyo yainzi pericardium. Inoitwa, akavapindurawo, vatatu akaturikidzana izvo dzakasiyana ukobvu, zvakasiyana specificity dzavo uye mabasa akasiyana mabasa. Maererano nemamiriro mwoyo rakakamurwa makamuri mana - the dhipatimendi. It asara uye ventricles kurudyi, kuruboshwe uye atria zvakanaka. Pakati kuruboshwe nezvakarurama mativi mukana partition. Zvakarurama atrium runoyerera kupinda negomba Vienna, uye kuti atrium kuruboshwe anofambirana pulmonary tsinga. Kubva ventricle kuruboshwe kunze vachikwira yeropa, uye kubva kurudyi - the pulmonary tsinga.

mwoyo anatomi wakananga nechokwadi chokuti ventricles havasi yunifomu mu ukobvu yavo. Somuenzaniso, kuruboshwe ventricle iri mumadziro mukobvu (katatu mukobvu kupfuura madziro kurudyi), sezvo kuruboshwe ventricle pumps ropa racho systemic riparadzirwe, naro kupararira yose muviri. Somugumisiro, mune hombe denderedzwa uye BP zvakawanda.

Kuti mwoyo pasingaguti chete ropa rakarasirwa mumwoyo ane mavharuvhu. Panguva imwe nguva mavharuvhu akavhara nzvimbo ropa aibuda, kana kurivhura. Saka, pane ropa riyerere iri achida mirayiridzo.

Kana anatomi mwoyo haina kuvaremedza pathological mananara, iro mutinhimira basa mwoyo. Cardiac basa unogona kuparadzaniswa zvinogara - imwe kutenderera ine muzvikamu zvitatu. Danho rokutanga rutapudzo rimwe atriums ropa yakazara. Kuburikidza akazaruka mavharuvhu ropa anopinda ventricles, izvo zvinozoita akaderedzwa, ndiEzekieri atrium - kuzorora. Panguva ino, basa rake kunoita vharuvhu kuvhara yokururamisa ropa. Munyaya inotevera kutotanga - kumbomira, ropa runoyerera nyore, apo moyo wakazorora. Izvi zvinoitika rebei - mahwanda wechipiri.

Anatomy mwoyo, uye basa rake - chinhu chakaoma kunzwisisa chaiyo. Pashure innervation zviri mumwoyo tsandanyama kunoitika nokuda zvakasiyana-siyana dzakadai ukama pakati huta uye kwemakemikari anobudiswa enyika, pamberi yakakwana yakawanda potassium ions uye calcium yakawanda. Kuti kudzidza basa mwoyo uye kugadzirisa matambudziko nemoyo basa, kuti unonzi, electrocardiograph. Achibatsirwa chidzidzo ichi, vakawanda hwakagara zvokuongorora kuti cardiac pathologies.
