Respiratory Rate

Function of the Respiratory system

maintain correct levels of carbon dioxide and oxygen in body tissues

What happens when CO2 levels rise?

H ions increase because CO2 combines with H2O to form carbonic acid

What happens to chemoreceptors during normal breathing when CO2 levels rise slightly above normal?

become stimulated due to a rise in CO2 induced H+ concentration and the resulting drop in pH

Regulation of respiration by CO2 induced H+ ion concentration is a example of what?

negative feedback

Hyperventilation results in

exhaling to much CO2, causing the pH of the blood to increase

What happens when too much CO2 is blown off?

The medullary respiratory center is less activated, resulting in shallow, slow respiration, causing too little intake of CO2

How do you reverse the effects of hyperventilation?

need to increase blood CO2 levels, the easiest way is to breathe into a paper bag
