Shin kun taɓa yin mamakin dalilin da yasa muke gumi idan muka gudu muka yi wasa, dalilin da yasa muke rawar jiki a ranar sanyi, ko kuma yadda za mu iya zama a farke ko da mun ɗan ci abinci a makare lokacin da muke jin yunwa? Bayan duk wannan akwai wani tsari mai ban mamaki da ke cikin jikinmu. A yau za mu yi magana game da wannan tsari mai ban mamaki wanda yake da mahimmanci ga rayuwarmu, wanda ake kira Homeostasis.
Mene ne homeostasis kawai?
A taƙaice dai, homeostasis tsari ne da jiki ke kula da yanayin cikin jikinmu, kamar zafin jiki , matakan sukari , da kuma yawan ruwa, a kowane lokaci, ba tare da la'akari da yadda yanayin waje ke canzawa ba. Yana kama da 'aikin gwaji' a cikin jikinmu. Muddin wannan tsari yana aiki yadda ya kamata, muna cikin koshin lafiya. Amma idan aka samu matsala a wannan daidaito , zai iya haifar da rashin lafiya har ma da mutuwa.
Ka yi tunanin na'urar sanyaya daki (AC) a gidanka. Idan ka saita shi zuwa 24°C, idan zafin ɗakin ya wuce wannan adadin, na'urar sanyaya daki (AC) tana kunnawa ta sanyaya ɗakin. Idan zafin ya faɗi ƙasa da 24°C, na'urar sanyaya daki tana kashewa kuma tana barin zafin ya koma yadda yake. Homeostasis wani abu ne kamar haka. Jikinmu koyaushe yana ƙoƙarin kiyaye komai a wani 'lokaci'.
Ga wasu muhimman abubuwa don kiyaye jikinmu ya daidaita ta wannan tsari:
| Ma'aunin sarrafawa | Bayani mai sauƙi |
|---|---|
| Zafin Jiki | Kula da yanayin zafi mai kyau ta hanyar gumi a lokacin zafi da kuma rawar jiki a lokacin sanyi. |
| Ciwon Jini | Rage matakan sukari ta hanyar amfani da insulin da glucagon hormones. |
| Hawan Jini | Sarrafa hawan jini ta hanyar canza bugun zuciya da faɗin jijiyoyin jini. |
| Ruwa da Electrolytes | Koda yana kula da daidaiton ruwan jiki ta hanyar canza yawan fitsari. |
Ta yaya wannan tsari yake aiki?
Tsarin homeostasis yana aiki ta hanyar haɗakar manyan sassa uku. Bari mu yi tunaninsa kamar tsarin tsaro.
1. Mai karɓa: Wannan shine 'sentinel' a jikinmu. Duk wani canji a cikin muhalli a ciki ko wajen jiki (misali, ƙaruwar zafin jiki, raguwar hawan jini ) waɗannan masu karɓa ne suka fara gano shi. Waɗannan na iya zama ƙwayoyin halitta ko kyallen takarda. Da zarar an gano canjin, wannan 'sentinel' yana aika saƙo zuwa cibiyar sarrafawa.
2. Cibiyar Kulawa: Wannan ita ce 'Ofishin Tsaro'. Wannan cibiyar galibi tana cikin kwakwalwarmu (musamman a wani ɓangare da ake kira Hypothalamus). Bayan karɓar saƙon daga 'mai gadi', wannan cibiyar ita ce ke yanke shawara kan abin da za a yi. Tana ba da umarni kamar, "To, zafin jikinka ya fi na yau da kullun, kana buƙatar rage shi."
3. Mai Tasiri: Wannan shine wanda ke ɗaukar 'Aikin'. Shi ne wanda ke aiwatar da umarnin da ya fito daga cibiyar sarrafawa. Misali, idan zafin jiki ya ƙaru, glandar gumi tana aiki kuma tana fara gumi bisa ga saƙon da ke fitowa daga cibiyar sarrafawa. Sannan jiki ya huce. Lokacin da hawan jini ya ƙaru, ayyuka kamar rage bugun zuciya ko faɗaɗa jijiyoyin jini suna faruwa.
A taƙaice dai, na'urar firikwensin tana gano bambanci, cibiyar sarrafawa tana yanke shawara, kuma na'urar kunna wutar lantarki tana aiwatar da wannan shawarar. Haɗin kai tsakanin waɗannan ukun ne ke kiyaye daidaiton jiki.
Tsarin Ra'ayoyin Masu Ba da Shawara
Jikinmu yana da manyan hanyoyi guda biyu don kiyaye wannan daidaito.
- Ra'ayi Marasa Kyau: Wannan ita ce hanyar da aka fi amfani da ita a cikin homeostasis. Abin da ke faruwa idan wani abu ya wuce matakin da aka saba, shine a mayar da shi zuwa matakin da aka saba. Kamar AC. Idan zafin jiki ya karu, ana rage shi. Idan matakin sukari ya karu, ana rage shi. Idan hawan jini ya karu, ana rage shi. Kullum yana faruwa ne ta hanyar yin wani abu sabanin canjin da kuma samar da daidaito.
- Ra'ayi Mai Kyau: Wannan ya ɗan yi wuya kuma ya bambanta. Wannan ya ƙunshi ƙara da hanzarta wani tsari da ke akwai. Mafi kyawun misali shine zubar jini .

Wani misali na wannan nau'in amsawa mai kyau shine matsewar mahaifa yayin haihuwa.
Me yasa homeostasis yake da mahimmanci a gare mu?
Homeostasis shine rayuwarmu. Ba tare da wannan tsari ba, ƙwayoyin da ke jikinmu ba za su iya aiki ba. Ka yi tunanin cewa zafin jikinmu yana canzawa kawai tare da zafin muhalli. Don haka, a cikin matsanancin zafi, ƙwayoyinmu na iya mutuwa.
Wannan rashin daidaito shine tushen cututtuka da yawa .
Misali, Ciwon suga (Diabetes Mellitus) wani rugujewa ne a tsarin homeostasis wanda ke sarrafa matakan sukari a jini. Yawanci, matakin sukari da ke ƙaruwa lokacin da muke cin abinci yana ƙarƙashin ikon insulin, wanda pancreas ke fitarwa. Lokacin da matakin sukari ya ragu yayin yunwa, ana fitar da Glucagon hormone don dawo da shi zuwa al'ada. A cikin ciwon suga, wannan tsari ba ya faruwa yadda ya kamata. Shi ya sa dole mu sha magunguna na waje don dawo da wannan daidaito.
Saboda haka, idan ka ji rashin daidaito ko canji mai ɗorewa a jikinka, yana da matuƙar muhimmanci ka yi magana da likitanka game da shi. Da magani mai kyau, sau da yawa ana iya dawo da matsalar homeostasis.
Me za mu iya yi don kiyaye wannan daidaito?
Ƙananan canje-canje a rayuwarmu na iya ba da babban ƙarfafawa ga wannan tsarin mai ban mamaki.
