In humans what happens when breathing rate increases?

Question

a)additional oxygen will diffuse into the blood as carbon dioxide diffuses outt of the blood in the lungs

b)changing os stored chemical energy in food molecules to a form usable by organism

c)conversion of light energy into the chemical bond energy of organic molecules

d)removal of oxygen from the cells of an organism

Answer 1

a)

Answer 2

breathing is controlled by specialized centers in the brainstem, which automatically regulate the rate and depth of breathing depending on the body’s needs at any time. When carbon dioxide levels increase in the blood, it reacts with the water in blood, producing carbonic acid. Lactic acid produced by anaerobic exercise also lowers pH. The drop in the blood's pH stimulates chemoreceptors in the carotid and aortic bodies in the blood system to send nerve impulses to the respiration centre in the medulla oblongata and pons in the brain. These, in turn send nerve impulses through the phrenic and thoracic nerves to the diaphragm and the intercostal muscles, increasing the rate of breathing.

This automatic control of respiration can be impaired in premature babies, or by drugs or disease.


Examples
For instance, while exercising, the level of carbon dioxide in the blood increases due to increased cellular respiration by the muscles, which activates carotid and aortic bodies and the respiration center, which ultimately cause a higher rate of respiration.

During rest, the level of carbon dioxide is lower, so breathing rate is lower. This ensures an appropriate amount of oxygen is delivered to the muscles and other organs. It is important to reiterate that it is the buildup of carbon dioxide making the blood acidic that elicits the desperation for a breath much more than lack of oxygen.

Answer 3

This isn't a very well written question but the best answer is:
a)
The other choices are absurd.

When a human being hyperventilates, he/she blows off a lot of CO2 and without increasing FIO2, the main effect will by respiratory alkalosis and if uncompensated metabollically rapidly enough will lead to bad things. This is a not a practical question, it's a question of philosophy, frankly.

Answer 4

the common is 12 to sixteen in keeping with minute. known is a thoroughly distinctive tale, as each and every individual has variables that element into what's known for them. case in point, somebody it is bodily energetic on a ordinary foundation, does not smoke, takes no drugs, drinks little or no caffeine, and the checklist is going on, might have a classic resting respiratory cost of 10. Take that very same individual and enable them to smoke, drink 8 cups of espresso in keeping with day, drink 3 glasses of iced tea, and their known resting respiratory must be 17. The time era "at relax" has some variables to contemplate besides. Do you think approximately somebody "at relax" while they are reclined staring at television? in the event that they are staring at a soccer recreation, or a racing experience, their respirations could be bigger than in the event that they have been merely reclined without exterior stimuli. i comprehend, that grow to be too lots for this sort of easy question. it relatively is merely that the question has no easy answer. the common physique temperature for human beings is ninety 8.6 F. My mom, 2 brothers, a sister, and that i all have a classic physique temperature of ninety six.8 F. If we take our temperature and it reads ninety 9.0 F, we've a fever. extra odd yet, we tend to drop a level or 2 if we get ill. by potential of how, my at relax respiratory is 10, without exterior stimuli.
