Some people train themselves to regulate their heartrate by relaxing and other methods. The slower your heartrate the less oxygen you use so the longer you can hold your breath. It is also mental strength, you can probably hold your breath longer than you think, if you just force yourself.

What is the difference between a fact and an opinon?
an opinion is what you think about it a fact is something true about it. like dolphins can't stay under water for 5 hours that is a fact and an opinion is like dolphins are cute some body might think that dolphins aren't cute but dolphins can't stay under water for 5 hours that is a fact because dolphins really can't stay under water for 5 hours or they wouldn't be living any more and we wouldn't have any dolphins and they would be extinct They would have to come up and breathe for air about every 30 min. to a hour.they can hold their breath longer than we can so that is still amazing to some people but other people might think that it is not cool but to me i think that is awesome cause nobody can hold their breath that long.that is the story between a fact and an opinion
What is the functions of diaphgram?
The function of the diaphragm is to go up when you inhalewhen you exhale it goes down it helps you breath so when you breathe say "Thank you diaphragm I think your special because if it wasn't for you I would be dead the first breath I take" SO REMEMBER ALWAYS BE CAREFUL AROUND YOUR DAIPHRAGM!!!!
When you hold your breath your brain sends a message to the diaphragm and rib muscles telling them to breathe . why is this?
The brain uses a CO2 - O2 feedback system. CO2 rises as O2 is depleted. The brain receives signals of rising CO2, and triggers the diaphragm.Incidentally, this system becomes reversed in emphysema and severe lung conditions. The brain becomes accustomed to rising CO2. IF too much O2 is administered externally, it will stop the brain from signalling the next breath. So while a person with healthy lungs can tolerate external O2 at 8 liters per minute, people with emphysema can only tolerate no more than 2 liters per minute---or the person will stop breathing.
