Kodi magazi amayenda bwanji m'thupi lanu lonse? (Kuyenda kwa Magazi ndi Dongosolo Loyenda kwa Magazi) Tiyeni tipeze yankho m'njira yosavuta!

Kodi munayamba mwadzifunsapo kuti chinthu ichi chotchedwa magazi chimayendera bwanji matupi athu popanda vuto lililonse? Kodi sizodabwitsa? Sekondi iliyonse yomwe mtima wathu ukugunda, kampompo kakang'ono aka kamayendetsa magazi kudzera mu dongosolo la machubu m'thupi lathu lonse. Ichi ndi chomwe timachitcha 'Cycle Circulatory System' . Machubu awa ali ngati machubu osinthasintha omwe amanyamula magazi kupita ku gawo lililonse laling'ono la thupi. Chabwino, tiyeni tikambirane za izi mwatsatanetsatane?

N’chifukwa chiyani magazi ndi ofunika kwambiri kwa ife?

Magazi ndi gawo lofunika kwambiri pa miyoyo yathu. Tangoganizani, ndi magazi awa omwe amathandiza selo lililonse laling'ono ndi minofu m'thupi lathu kuti likhale ndi moyo ndikugwira ntchito. Nazi zinthu zazikulu zomwe zimachitika ndi magazi:

• Magazi amanyamula mpweya ndi michere yofunika kwambiri m'thupi lathu, monga momwe amabweretsera chakudya ndi zakumwa m'nyumba zathu.
• Magazi amathandizanso kuchotsa mpweya woipa wa carbon dioxide ndi zinyalala zina zomwe zimasonkhana m'thupi ndi kuzitulutsa m'thupi, monga momwe zimakhalira ndi kutaya zinyalala m'nyumba mwanu.
• Chifukwa cha zonsezi, magazi ndi ofunikira kuti tipitirize kukhala ndi moyo komanso kuti ziwalo zonse za thupi lathu zikhale zathanzi .

Kodi mukumvetsa kufunika kwa magazi?

Pali mitundu itatu ikuluikulu ya mitsempha yamagazi!

Pali mitundu itatu ikuluikulu ya mitsempha yamagazi yomwe imathandiza kusuntha magazi awa m'thupi lathu. Monga momwe misewu ilili ndi misewu ikuluikulu, misewu yaying'ono, ndi misewu ya m'mbali.

1. Mitsempha yamagazi - mitsempha yamagazi yomwe imanyamula magazi oyera kuchokera mumtima

Mitsempha yamagazi ndi mitsempha yamagazi yomwe imanyamula magazi ochulukirapo omwe ali ndi mpweya (nthawi zambiri amawonetsedwa muzithunzi zofiira) ndi michere kuchokera mumtima mwathu kupita ku minofu ina yonse m'thupi. Taganizirani ngati mtima ndi pampu yamadzi, ndipo mitsempha yamagazi ili ngati mapaipi akuluakulu omwe amanyamula madzi oyera kuchokera papampuyo kupita kumunda wonse.

• Dongosolo la mitsempha yamagazi limeneli limayamba ndi aorta, mtsempha waukulu kwambiri wamagazi womwe umatuluka mumtima. Uli ngati chitoliro chachikulu kwambiri chomwe chimatuluka mu thanki lalikulu la madzi.
• Izi zimanyamula magazi okhala ndi mpweya wochuluka kuchokera mumtima kupita ku minofu yonse ya thupi.
• Pamene mukupita kutali ndi mtima, mitsempha iyi imagawikana kukhala nthambi, pang'onopang'ono imayamba kuchepa. Monga momwe mtsinje waukulu umagawikira kukhala mitsinje ing'onoing'ono.

Choncho, ntchito yaikulu ya mitsempha yamagazi ndi kugawa magazi abwino m'thupi lonse .

2. Ma capillaries - malo ocheperako osinthira ndalama

Ma capillaries ndi netiweki ya mitsempha yamagazi yaying'ono kwambiri komanso yopyapyala kwambiri. Izi ndi zomwe zimalumikiza mitsempha iwiri ikuluikulu yamagazi, mitsempha yamagazi ndi mitsempha yamagazi. Taganizirani izi ngati mndandanda wa misewu yaying'ono ya m'mbali pakati pa misewu iwiri ikuluikulu.

• Makoma a mitsempha yamagazi iyi ndi opyapyala kwambiri, ngati ukonde.
• Makoma opapatizawa amalola zinthu zabwino monga mpweya ndi michere kupita ku maselo a minofu kuchokera m'magazi, komanso zinthu zosafunikira monga carbon dioxide ndi zinyalala zomwe zimapangidwa m'maselo a minofu kubwerera m'magazi . Zili ngati kusinthana katundu pamsika.

Ndipotu, kusinthana kofunikira kumeneku pamlingo wa maselo a thupi kumachitika kudzera m'mitsempha yaying'ono iyi. Ndi yaying'ono kwambiri, ina ndi yopyapyala kuposa tsitsi lathu! Koma ntchito yomwe amagwira ndi yayikulu, sichoncho?

3. Mitsempha - mitsempha yomwe imanyamula magazi oipa kubwerera kumtima

Mitsempha ndi mitsempha yamagazi yomwe imanyamula magazi "odetsedwa" kapena "odetsedwa" (nthawi zambiri amawonetsedwa pabuluu pazithunzi) kuchokera ku minofu ya thupi lathu kubwerera kumtima. Ili ngati dongosolo la mapaipi lomwe limasonkhanitsa madzi ogwiritsidwa ntchito ndikubwezeretsa ku thanki.

• IziMitsempha yamagazi imanyamula magazi okhala ndi mpweya wochepa komanso mpweya wochuluka wa carbon dioxide kuchokera m'thupi kupita kumtima.
• Pamene mitsempha iyi ikuyandikira mtima, imalumikizana pamodzi ndikukula. Monga momwe mitsinje yaying'ono imalumikizirana kupanga mtsinje waukulu.
• Pomaliza, mtsempha waukulu wotchedwa `superior vena cava` umabweretsa magazi kuchokera kumutu ndi m'manja kupita kumtima. Mofananamo, mtsempha waukulu wotchedwa `inferior vena cava` umabweretsa magazi kuchokera m'mimba ndi miyendo kupita kumtima.

Kotero ntchito yaikulu ya mitsempha ndi kubweretsa magazi okhala ndi zinyalala zomwe zimasonkhana m'thupi kubwerera kumtima ndikuzitsogolera kuti ziyeretsedwe .

Kodi dongosolo la mitsempha yamagazi ili lalikulu bwanji kuposa momwe mukuganizira?

Tsopano mutha kuona momwe dongosolo la mitsempha yamagazi, mitsempha yamagazi, ndi mitsempha yamagazi lilili lovuta m'thupi lathu. Kodi mukudziwa kuti dongosolo lonse la mitsempha yamagazi - ndiko kuti, mitsempha yonse yamagazi, mitsempha yamagazi, ndi mitsempha yamagazi pamodzi - ndi lalitali kuposa makilomita 60,000 ! Magazi athu amayenda m'dongosolo lalikululi nthawi zonse. Zili ngati misewu mumzinda, yokhala ndi magalimoto opita uku ndi uku nthawi zonse. Choncho amene amathandiza kupopa magazi onsewa m'thupi lonse ndi mtima wathu. Ndiwo amene akutsogolera ntchitoyi yonse.
