Tiyeni timvetse bwino momwe magazi amayendera m'thupi lathu? (Njira Yoyendera Magazi)

Moni! Muli bwanji? Lero tikambirana za dongosolo lodabwitsa komanso lofunikira kwambiri m'thupi lathu. Umenewo ndi dongosolo lathu lozungulira magazi, kapena monga ena amalitchulira, ``Circulatory System``. Nthawi zina mwina mudamvapo kuti limatchedwa ``Cardiovascular System``. Zonsezi ndi mayina a dongosolo lomwelo. Choncho, tiyeni tiwone chomwe chili, momwe chimagwirira ntchito, komanso momwe tingachisungire bwino.

Kodi dongosolo lozungulira magazi ndi chiyani? Mwachidule...

Mwachidule, dongosolo la magazi m'thupi lanu limapangidwa ndi mtima ndi mitsempha yamagazi . Zonsezi pamodzi zimagwiritsa ntchito magazi kunyamula michere kupita ku selo iliyonse m'thupi lathu ndikuchotsa zinyalala m'maselo amenewo.

Ganizirani mtima wanu ngati pampu yamadzi. Pampu iyi imapopa magazi kudzera mu netiweki yovuta ya mitsempha yamagazi m'thupi lanu lonse. Mitsempha iyi imatchedwa mitsempha ndi mitsempha . Magazi awa amanyamula mpweya - mpweya wopatsa moyo womwe timapuma - ndi zakudya ku minofu yanu, minofu, ndi ziwalo. Ndi njira yomweyi yomwe imasonkhanitsa zinyalala ndikuzinyamula kupita nazo ku ziwalo komwe zingachotsedwe.

Kodi ntchito zazikulu za dongosololi ndi ziti?

Dongosolo lathu lozungulira magazi limagwira ntchito zazikulu zitatu:

1. Kunyamula magazi m'thupi lonse.

2. Kunyamula mpweya ndi zakudya m'thupi kupita ku ziwalo zathu, minofu, ndi minofu.

3. Mpweya wa carbon dioxide – mpweya womwe sulinso wothandiza m'matupi athu ndipo umatulutsidwa tikamapuma – ndi kuchotsa zinyalala ndi zinyalala za mankhwala m'ziwalo zathu.

Usana ndi usiku, ngakhale mutakhala m'tulo, mtima wanu umapopa magazi nthawi zonse m'thupi lanu lonse, ngati kuti ukuyenda mozungulira. Ngati titsatira njira ya magazi iyi, imayambira mumtima ndikuyenda m'mitsempha ikuluikulu yamagazi yotchedwa ``Mitsempha yamagazi'' kuti igawire magazi ku ziwalo ndi minofu yathu.

Mkati mwa minofu yathu, mu netiweki ya mitsempha yamagazi yabwino kwambiri yotchedwa capillaries , mpweya womwe uli m'magazi umatulutsidwa ndipo zinyalala zimabwezedwanso m'magazi. Mukachoka m'minofu ndi ziwalo izi, magazi awa amabwerera kumtima kudzera m'mitsempha yamagazi yotchedwa mitsempha. Kenako magazi awa amayenda kudzera mumtima kupita ku mapapo, komwe amaperekedwanso mpweya, ndipo ulendo umayamba. Izi zimachitika kambirimbiri patsiku, sekondi iliyonse yomwe mtima wanu ukugunda.

Tangoganizani, mtima wanu umapopa magazi okwana malita 7,500 m'thupi lanu tsiku lililonse! Munthawi ngati izi, mukamachita masewera olimbitsa thupi, mtima wanu umapopa magazi ambiri. Izi zikutanthauza kuti kayendedwe ka magazi m'thupi lathu kamasinthasintha malinga ndi kuchuluka kwa magazi ndi mpweya womwe thupi lathu limafunikira.

Chimodzi mwa ntchito zazikulu za dongosolo lathu lozungulira magazi ndikupereka magazi nthawi zonse ku ubongo ndi mtima.Chifukwa, ngati ubongo sulandira kuchuluka kwa magazi kofunikira, ukhoza kutaya chidziwitso mkati mwa masekondi ochepa. Ngati magazi asiya kuyenda kwa mphindi zinayi, ubongo ukhoza kuwonongeka. Mofananamo, ngati mtima sulandira magazi okwanira, ntchito yake yopopera madzi imayamba kulephera msanga.

Ndiye, magazi awa amalowa bwanji m'thupi lonse?

Dongosolo lathu loyendetsa magazi, kapena kuti ``Cardiovascular System``, limagwira ntchito mothandizidwa ndi mitsempha yamagazi. Mitsempha ina yamagazi (``Veins```) imabwezeretsa magazi mumtima, pomwe mitsempha ina yamagazi (``Mitsempha yamagazi``) imachotsa magazi mumtima.

Mitsempha yanu yamagazi, pamodzi ndi mtima ndi mapapo anu, zimapopa magazi m'thupi lanu lonse mosalekeza. Umu ndi momwe zimagwirira ntchito:

1. Magazi omwe alibe mpweya wabwino amapopedwa kuchokera ku ventricle yakumanja ya mtima kupita ku mapapo. Magazi awa amayenda kudzera mu thunthu la mapapo (mtsempha waukulu wa mapapo).

2. Mpweya umawonjezeredwa ku magazi awa mkati mwa mapapo anu.

3. Mitsempha ya m'mapapo imanyamula magazi olemera mpweya kuchokera m'mapapo kupita ku atrium yakumanzere ya mtima.

4. Kuchokera ku atrium yakumanzere, magazi olemera mpweya amatumizidwa ku ventricle yakumanzere. Gawo la minofu la mtima limapompa magazi kupita ku thupi lonse kudzera m'mitsempha.

5. Pamene magazi akuyenda m'thupi lonse komanso m'ziwalo, amapereka zakudya, amagawa mahomoni, komanso amasonkhanitsa zinyalala.

6. Kenako, mitsempha imabweretsa magazi omwe alibe mpweya wokwanira komanso okhala ndi mpweya woipa wa carbon dioxide kumtima. Kuchokera mumtima, magaziwo amatumizidwanso ku mapapo.

7. Mkati mwa mapapo, mpweya wa carbon dioxide umatulutsidwa ndipo mpweya wa oxygen umawonjezeredwa m'magazi posinthana. Kenako, mukatulutsa mpweya, mpweya wa carbon dioxide umatulutsidwa.

Njira yopezera mpweya kuchokera m'mapapo ndikubwerera kumtima imatchedwa pulmonary circulation . Njira yoperekera magazi okhala ndi mpweya m'thupi lonse imatchedwa systemic circulation .

Kodi dongosololi lili kuti?

Mtima wanu uli pakati pa chifuwa chanu. Umalumikizidwa ndi mitsempha yamagazi yomwe imanyamula magazi m'thupi lanu lonse.

Kodi ziwalo za dongosolo lozungulira magazi ndi ziti?

Mtima wanu ndi mitsempha ya magazi ndi zomwe zimapanga dongosolo lozungulira magazi. Chigawo chilichonse chili ndi ntchito yake yothandiza kusuntha magazi m'thupi lanu lonse. Umu ndi momwe maselo athu amapezera mpweya ndi michere komanso momwe zinyalala zimachotsedwera.

Kodi mbali zinayi zazikulu za dongosolo lozungulira magazi ndi ziti?

Mbali zazikulu za dongosolo la magazi ndi izi:

• Mtima: Ichi ndi chiwalo chopangidwa ndi minofu. Chimapopa magazi m'thupi lonse. Mtima ndi chiwalo chokhacho chomwe chimagwira ntchito m'mitsempha yamagazi. Mapapu anu ndi a m'mitsempha ya kupuma.
• Mitsempha yamagazi: Iyi ndi machubu opyapyala, a minofu omwe amanyamula magazi okhala ndi mpweya kuchokera mumtima kupita ku ziwalo zonse za thupi. Mtsempha waukulu kwambiri m'thupi lathu ndiMitsempha ya mtima imayenda kuchokera ku aorta, kenako ikachoka pamtima, imagawikana kukhala mitsempha yaying'ono (arterioles).
• Mitsempha: Mitsempha iyi imanyamula magazi opanda mpweya kubwerera kumtima. Mitsempha imayamba ndi yaying'ono (ma venule) kenako imakula ikayandikira mtima. Mitsempha ikuluikulu iwiri (vena cava yapamwamba ndi vena cava yapansi) imanyamula magazi kupita kumtima. Mitsempha ya m'miyendo yanu ili ndi ma valve omwe amaletsa magazi kuyenda m'mbuyo.
• Ma capillaries: Mitsempha yamagazi iyi imalumikiza mitsempha yaying'ono kwambiri (arterioles) ndi mitsempha (venule). Makoma a mitsempha yamagazi ndi ofooka kwambiri, zomwe zimathandiza kuti mpweya, carbon dioxide, michere, ndi zinyalala zidutse kuchokera m'magazi kupita ku maselo, komanso kuchokera ku maselo kupita ku magazi.

Kodi dongosolo la magazi limawoneka bwanji? Kodi ndi lalikulu bwanji?

Mungaganize kuti mtima ndi malo opopera magazi m'thupi. Umalumikizidwa ndi netiweki ya mitsempha yamagazi yomwe imafalikira m'thupi lonse.

Ngati munaonapo mapaipi amadzi kapena mapaipi a zimbudzi pansi pa msewu, mukudziwa kuti ndi akuluakulu. Mapaipi amenewa amagawikana kukhala ang'onoang'ono omwe amabweretsa madzi m'nyumba ndipo amanyamula zimbudzi. Mofananamo, mitsempha yamagazi yomwe imanyamula magazi kupita ndi kuchokera mumtima ili ngati mapaipi akuluakulu omwe ali pansi pa msewu. Ndi mitsempha yamagazi yayikulu kwambiri m'thupi. Mukachoka pamtima, nthambizi zimagawikana kukhala mitsempha yamagazi yaying'ono yomwe imathandiza kufalitsa mpweya m'thupi lonse ndikuchotsa zinyalala.

Mitsempha yamagazi imapangidwa ndi zigawo za minofu yolumikizana, minofu, ndi ulusi wotanuka. Minofu ya mitsempha yanu yamagazi imalamulira kukula kwake. Izi zimakhudzanso kuthamanga kwa magazi . Mitsempha yamagazi ikakula, izi zimatchedwa ``Vasodilation,'' ndipo kuthamanga kwa magazi kumachepa. Mitsempha yamagazi ikachepa, izi zimatchedwa ``Vasoconstriction,'' ndipo kuthamanga kwa magazi kumawonjezeka.

Mtima wanu umapangidwa ndi minofu ndi minofu ina. Magazi amadutsa m'zipinda zinayi.

Mtima wanu nthawi zambiri umakhala ngati chibwano chanu. Koma ngati muli ndi matenda a mtima, ukhoza kukhala waukulu kwambiri. Mitsempha yanu yamagazi imathamanga thupi lonse, kuyambira pamwamba mpaka pansi. Kotero netiweki iyi ndi yayikulu monga momwe mulili wamtali komanso wotakata. Ndipotu, pali mitsempha yamagazi yoposa makilomita 60,000 m'thupi lathu!

Mtima wamba umalemera pakati pa ma ounces 8 ndi 12, koma izi zimatha kusiyana malinga ndi jenda, kulemera kwa thupi lonse, komanso matenda.

Kodi matenda ndi matenda otani omwe amakhudza dongosolo la magazi ndi chiyani?

Mavuto ambiri omwe amakhudza mbali zina za kayendedwe ka magazi amayamba chifukwa cha kuyenda pang'onopang'ono kwa magazi m'mitsempha yamagazi. Popeza mitsempha yathu yamagazi imapereka mpweya m'thupi lonse, ngati mitsempha ina yamagazi yatsekedwa, zimakhala zovuta kupereka mpweya umenewo.

Nazi mavuto ena omwe amakhudza dongosolo la magazi:

• Kuthamanga kwa magazi
• Cholesterol yambiri
• Arrhythmia (kugunda kwa mtima kosazolowereka)
• Matenda amtima
• Kulephera kugwira ntchito kwa valavu ya mtima
• Kulephera kwa mtima ('Kulephera kwa mtima' - kufooka kwa minofu ya mtima wanu)
• Aneurysm nthawi zambiri imapezeka mu aorta kapena ubongo.
• Stroke
• Atherosclerosis - kuchuluka kwa ma plaque m'mitsempha yanu
• Matenda a mtima
• Matenda a mitsempha yamagazi ( monga, kutsekeka kwa mitsempha yakuya ndi pulmonary embolism)

Kusintha moyo wanu mosavuta komanso malangizo oti musunge dongosolo lanu la magazi kukhala lathanzi

Pali zinthu zambiri zomwe mungachite kuti mtima wanu ndi mitsempha yamagazi zikhale zathanzi. Nazi zina mwa izo:

• Chitani masewera olimbitsa thupi nthawi zonse. Yesetsani kuchita masewera olimbitsa thupi osachepera mphindi 150 pa sabata.
• Kugona mokwanira usiku uliwonse.
• Kulamulira kuthamanga kwa magazi.
• Kuwongolera kuchuluka kwa cholesterol m'magazi.
• Kupewa zinthu zopangidwa ndi fodya.
• Kudya zakudya zopatsa thanzi la mtima. Mwachitsanzo, zakudya zokhala ndi ulusi wambiri komanso mafuta ochepa okhuta.
• Kusunga kulemera koyenera kwa inu.
• Kusunga shuga m'magazi mwabwinobwino.
• Pezani njira zabwino zochepetsera nkhawa.

Kodi nkhani ya magazi ofiira ndi abuluu ndi yoona? Kodi mitsempha yamagazi nthawi zonse imakhala ndi magazi okhala ndi mpweya?

Anthu ena amaganiza kuti magazi abuluu amayenda kudzera m'mitsempha m'mbali zina za thupi lathu. Koma kwenikweni, dontho lililonse la magazi athu ndi lofiira. Magazi amapeza mtundu wofiira kuchokera ku puloteni yokhala ndi iron yotchedwa hemoglobin . Izi zimapezeka m'maselo ofiira a magazi. Anthu ena amatcha magazi omwe ali ndi mpweya wambiri kuti "magazi ofiira."

Mitsempha yanu imanyamula magazi omwe ali ndi mpweya wochepa. Nthawi zina izi zimatchedwa "magazi abuluu" chifukwa mitsempha yanu imatha kuoneka yabuluu pansi pa khungu lanu. Koma magaziwo ndi ofiira kwenikweni. Mitsempha imakhala yabuluu wakuda chifukwa cha mpweya wochepa.

Mitsempha yamagazi imanyamula magazi ambiri okhala ndi mpweya. Komabe, pali zosiyana ziwiri: mtsempha wamagazi wa m'mapapo ndi mtsempha wamagazi wa m'mapapo. Mtsempha wamagazi wa m'mapapo umanyamula magazi opanda mpweya kupita nawo ku mapapo. Mtsempha wamagazi wa m'mapapo umanyamula magazi okhala ndi mpweya kubwerera kumtima.

Pomaliza, zomwe muyenera kukumbukira! (Uthenga Wopita Nawo Kunyumba)

Dongosolo lanu la magazi ndi lodabwitsa lomwe limagwira ntchito yofunika kwambiri kuti mukhale ndi moyo, limapereka mpweya ndi michere nthawi zonse. Muli ndi mphamvu zolimbitsa mtima wanu ndi mitsempha yamagazi.Kusiya kusuta fodya, kudya zakudya zabwino, kuchita masewera olimbitsa thupi, komanso kuwongolera kuthamanga kwa magazi ndi kuchuluka kwa cholesterol m'magazi ndi zabwino pa kayendedwe ka magazi. Funsani dokotala wanu zomwe mungachite kuti muteteze ndikulimbitsa mtima wanu ndi mitsempha yamagazi. Khalani ndi thanzi labwino!
