Question

When homeostasis is disturbed by increasing CO2 level & decreasing pH and O2 levels are cardioacceleratory centers stimulated or inhibited?

Answer 1

Explanation:When homeostasis is disturbed by increasing CO2 levels and decreasing pH and O2 levels, the cardioacceleratory centers in the medulla oblongata of the brainstem are stimulated.

This is because the body responds to the increase in CO2 levels and decrease in pH by triggering the respiratory center in the medulla oblongata to increase the rate and depth of breathing, which in turn increases the delivery of oxygen to the tissues and removes excess CO2. The increase in respiratory rate and depth is accompanied by an increase in heart rate and contractility, which is mediated by the cardioacceleratory centers in the medulla oblongata. This response helps to restore the balance of oxygen and carbon dioxide levels in the body and maintain homeostasis.

Answer 2

The two religions that were the fastest growing during the Second Great Awakening were Methodism and Baptism.

When homeostasis is disturbed by increasing CO2 level and decreasing pH and O2 levels, the cardioacceleratory centers are stimulated. This is because these changes are detected by chemoreceptors in the carotid and aortic bodies, which then send signals to the cardioacceleratory centers in the medulla oblongata to increase heart rate and respiratory rate in order to restore homeostasis.
