Introduction:
Hyperventilation is the process of taking in of extra amounts of O2 at an abnormally rapid rate and hypoventilation is the process of taking in of lesser amount of O2 than normal intake of oxygen intake. A person can hyperventilate and can hypo ventilate according to his own will. Due to hyperventilation and hypoventilation the levels of CO2 and
Answer to Problem 1U
Correct answer:
If someone holds his breath for a long time his body CO2 levels are likely to increase and his
Explanation of Solution
Reason for the correct statement:
By the process of hypoventilation, CO2 gets accumulated in a person’s body. CO2 forms carbonic acid and hence the level of
On holding the breath for a long time there will be accumulation of CO2 because there will be no intake of oxygen. This implies that by holding the breath for a long time the levels of carbon dioxide will increase.
Option c. is given as “increase; decrease”.
As, “if someone holds his breath for a longer time the levels of carbon dioxide will increase and the value of
Hence, the option c. is correct.
Reason for the incorrect statements:
Option a. is given as “increase; increase”.
The value of
Option b. is given as “decrease; increase”.
Levels of carbon dioxide will decrease if a person does not take breath and consequently his value of
Option d. is given as “decrease; decrease”.
On holding the breath there will be accumulation of CO2 so there will be an increase in the levels of CO2 so its value will decrease, so it is a wrong answer.
Hence options a., b. and d. are incorrect.
There will be hypoventilation in case of holding of breath by a person and subsequently the levels of CO2 will increase and as per its consequences the

- Most of the CO2 is transported through the bloodstream as…arrow_forwardDescribe what happens in the respiratory system when you run to catch a bus by placing the following in order (#1-7). Consider that the running will have caused an increase in cellular respiration, which results in an increase in CO2 (this is the change in the variable). The increase in CO2 will be detected by the brain, which will ultimately cause an increase in ventilation. Blood CO2 levels increased and O2 levels decreased. Increased ventilation results. Chemoreceptors detect decreased O2 and increased concentration of CO2/decreased pH. Return to normal CO2 and O2 levels. Respiratory centers increases its stimulation of spinal nerves (phrenic and intercostal). Increased frequency and degree of contraction of respiratory muscles. Central and peripheral chemoreceptors stimulate the respiratory centers in the brainstem. Increased cellular respiration in response to the running.arrow_forwardProlonged panic attack, that is characterized by hyperventilation, can lead to: Select one: a. Respiratory alkalosis b.
