CHEMICAL REGULATION

• Chemoreceptors

- Peripheral

- Central

- Pulmonary and Myocardial

• Effect of pO2, pCO2 and H Concentration on

Respiration

- Effect of Hypoxia

- Effect of Hypercapnia

- Effect of Arterial pH

- Interaction of pO2, pCO2, and pH in Regulation of

Respiration

Nafas quyidagi mexanizmlar yordamida boshqariladi:

-respirator reflekslar- ularning yuzaga kelishida quyidagi retseptorlar ahamiyatli :cho’zilishni sezuvchi retseptorlar, irritant retseptorlar, J- retseptorlar, ko’krak qafasu devorining retseptorlari

- kimyoviy kontrol mexanizm- arterial qondagi CO2 O2, H ionlari konsentratsiyasiga bog’liq bo’lib, kimyoviy retseptorlar orqali boshqariladi.
