What forces a person to take a breath?
An involuntary reflex. When a person holds his or her breath and manages to continue holding it, eventually the individual will lose consciousness due to the lack of oxygen being supplied to the brain. At this point in time, the person can no longer continue to force the body to suffocate itself, and the body will then begin to breathe again while the person is unconscious.
Actually, it's not the lack of oxygen, it's the build up of carbon dioxide that triggers the autonomic nervous system to force you to breathe.

Well , the average person takes 28,880 breaths a day, so 28,880 times 365 is a grand total of 10,541,200 breaths a year.
The new record for breath-holding is 19 minutes and 21 seconds. . There are tricks to holding your breath for long periods of time, but the practice can be dangerous. . There may be long-lasting health consequences to extreme breath-holding. . A Swiss freediver held his breath underwater fo…r 19 minutes and 21 seconds, according to news reports this week. The gasp-inducing feat beat the previous world record by 19 seconds, and blew away the record of 17 minutes and four seconds that magician David Blaine set on Oprah Winfrey's talk show in 2008. For most ordinary humans, all that breath-holding can be hard to fathom. The feat might also bring up some basic questions about biology. For example: Is it really possible to survive without inhaling for that long? And is it healthy? ( Full Answer )
If humans exhale carbon dioxide and mouth to mouth resuscitation is used to force oxygen into a person isn't the rescuer forcing carbon dioxide not oxygen into the lungs of the person not breathing?
Only a proportion of the air exhaled is carbon dioxide there is plenty of Oxygen there to do what is required under normal circumstances. People don't use all of the oxygen they breath in, a % of it is blown right back out of the body again.
Oxygen is necessary for the muscles, tissues, and organs in your body. It is also extremely important for the brain to function, as a prolonged period of not-enough oxygen to the brain will result in brain damage and more severely brain death. When you breathe, the Oxygen is inhaled into your lun…gs where it diffuses into the blood oxygenating the blood that is lacking oxygen as your heart pumps this non-oxygenated blood to the lungs. Once the blood has been oxygenated by the lungs, the heart continues pumping this blood throughout the body and delivers the oxygenated blood to the various tissues, muscles, and organs in your body. Then this blood is no longer containing oxygen, so the heart continues to pump it back through the heart and to the lungs to be re-oxygenated. And the cycle continues with each breath you take... Oxygen is needed in the reformation of Adenosine Triphosphate (ATP) from ADP in the body. ATP is used in metabolic processes as an energy source and is therefore required for life. ( Full Answer )

For every minute that passes by a normal human adult takes 12 to 20 breathes. That is 720 to 1,200 breaths an hour, 17,280 to 28,800 a day, and 6,307,200 to 10,512,000 a year. To get an accurate answer you would have to calculate the about of breathes a person takes as an infant (25 to 50 breathes p…er minute) and also as a child (15 to 30 breathes per minute).

Let us examine the mechanics of a jumping person. First the person imparts some force on the ground over a small amount of time, this is known as an impulse. This impulse gives the person an upward speed which is reduced, by gravity, to zero at the apex of the jump. Gravity still acting on the perso…n accelerates them back to the earth hitting with the same speed they jumped up with. Because of the symmetry of the problem it will take the same amount of time for the person to go from 0 to 3 feet as it will from 3 feet back to the ground (0 feet). Using the equations of motion we can calculate for how long it would take to free fall from 3 feet at initial velocity of 0. gravity = 32.2 [ft/s^2] Time = (2*3 [feet] / gravity)^0.5 = 0.432 [seconds] Next, using the equations of motion still, we calculate the speed we would hit the ground with falling from 3 feet. Speed = gravity * Time = 9.48 [mph] Knowing our speed and mass we can calculate the amount of momentum we have right as we jump. momentum = mass * speed = 51.81 [lbs*sec] Now here is the interesting part, the amount of force required to achieve that momentum depends on how fast your muscles "twitch". Impulse is force times time. 51.81 [lbs*sec] Force = ------------------- time [sec] This says that if you could apply approx 52 pounds of force for 1 second you would have enough velocity to reach 3 feet above ground. This answer of course is not reasonable as the total time to jump 3 feet and land again is less than one second. A more reasonable time needs to be considered. Think about how a person jumps, first the bend their legs and then very quickly push against the ground. Lets say that this happens in a range of between 0.05 and 0.15 seconds. For a time of 0.05 seconds the calculation is: Force = 51.81/0.05 = 1036 pounds This too may seem unreasonable let us examine the case for 0.15 seconds Force = 51.81/0.15 = 345.4 pounds It seems that the answer may lie somewhere in between those two values. The value for the amount of time could be determined for an individual experimentally. Have a stop watch running and the person of interest performing a jump. Make sure both are in the frame of the camera. Rewind and watch frame by frame to get an estimate of how long the muscles are working. This of course will give you an average value but is probably within the scope of what you are looking for. ( Full Answer )

In the absence of oxygen, the build up of carbon dioxide causes and increase in the hydrogen ion concentration of the blood. It is this increase in hydrogen ions that triggers what is basically a pain response, forcing the urge to breath. It may be interesting to also note that some medications i…ncrease hydrogen ion concentration, and thereby tend to increase rates of respiration. ( Full Answer )
yes, if there is no problem with their lungs.

Asthma is a complex medical problem in which both airway inflammation, bronchoconstriction, and excess mucous production play a role in causing shortness of breath. Bronchoconstriction causes a decreased diameter of the small airways, which makes air passage more difficult. Inflammation and excess m…ucous production cause plugging of these smaller airways, making air movement impossible and resulting in air trapping. As a result, a patient with asthma can take a breath in, but cannot exhale all of that air. ( Full Answer )

In a first aid situation you put your ear to a persons mouth and look for sings of chest movement.
The ribs themselves don't expand, but the muscles in between the ribs (the intercostal muscles) contract which pulls the ribs upwards and outwards. This expands the thoracic cavity, the pressure inside the thoracic cavity (and therefore lungs) will therefore become lower than the atmospheric pressur…e, so air is drawn in. (Air moves from areas of higher pressure to lower pressure) ( Full Answer )
you need to breath in order for ur blood flow and ur blood has to flow to the heart wen ur running ur heart is going fast cuz it needs the blood to flow faster so u can keep going and wen ur done running ur blood is going soo fast you need to breath fast

give breaths without chest compressions for adults give 1 breath every 5-6 seconds about 10-12 breaths per minute
Look, listen and feel. Look for chest rise, listen for airflow, and feel for air on your cheek. Also, take a CPR class!
If you do not suspect that there is a head, neck or upper back injury, first tilt the head way back to open the airway. Next put your face next to the person's mouth and nose and look at their chest. Then, for 10 seconds, Look, Listen, and Feel -- Look for the chest to rise and fall, Listen for th…e sound of breath from the nose or mouth, and Feel on the side of your face for the person's breath. If you do not detect any signs of breathing within the 10 seconds, begin CPR. . If you do suspect an injury to the head, neck or upper back, do not tilt the head back to open the airway. Instead, perform a jaw thrust to open the person's airway. If you are not sure how to do it, just grab their chin and pull it forward as far as it will go without moving the head. ( Full Answer )
Is it likely that when a person takes a breath they are inhaling the atoms of Shakespeare's last breath?
A very basic estimate to answer this question is to calculate how much air you breath in and out with each breath, and then compare that to the amount of air we could breathe in the atmosphere. The diameter of the earth is about 13000 km. Let's assume that atmospheric pressure is 1 ATM from sea l…evel to 1 km in altitude. Calculate the volume in this slice of atmosphere (ID = 13000 km, OD = 13001 km). Humans breathe in about 500 mL of air per breath. Compare these two numbers for your basic estimate. Of course this is not really right. CO2 that shakespeare breathed out is probably part of a tree or stuck at the bottom of the ocean, but that's no fun to calculate. ( Full Answer )
The average Adult will take 15 to 20 full resperations in a relaxed state per min
When you breath out, you always breath out water vapor along with air. However, you can't usually see the water vapor because the water molecules are not close enough to form individual droplets. Individual droplets can be seen at the dewpoint. The dew point is associated with relative humidi…ty. A high relative humidity indicates that the dew point is closer to the current air temperature. If the relative humidity is 100%, the dew point is equal to the current temperature. Cool air can hold less moisture, which is why dew forms on the ground overnight, when the air cools. Back to your question: If the air has a higher humidity, you'll be able to see your breath at a higher temperature. If the air has low humidity, it will take a cooler temperature to be able to see your breath. This is why you can see your breath in the winter much more easily than in the summer. ( Full Answer )

What is The maximum amount of air a person can exhale after taking the deepest breath possible is the?
The vital capacity. Â In a normal, healthy adult human, it is about 4-5 liters. \n
Yes, when you inspire you take in a breath; when you expire you breathe out.
It takes approximately 3 seconds to breathe in and 3 seconds to breath out for regular breathing. It will be less time the faster your respiration rate is.
You breath in oxygen for your blood to take to your brain so you can think. If you run low on air you become tired and yawn so you get more air to your brain.
Because your body is Oxygen Debt, and lactic acid is being produced in the muscles at a higher rate, so your body pumps blood to these muscles, quicker, to remove the lactic acid and supply them with glucose.
When they make that noise when their mouth opens, they are sweating. they don't have skin to sweat through so they breath through their mouth.
A newborn usually takes their first breath in the first minute of life, out of the womb. After a long or difficult labor, there is sometimes a short delay in those first minutes - this is not a medical emergency as long as the umbilical cord is still attached and pulsating the infant is being oxygen…ated by the placenta. The attending Mid-Wife, Nurse or MD will begin stimulating the baby by wiping his or her body vigorously with a towel or blanket, if this doesn't cause the baby to take a breath, they may thump the sole of the baby's foot to cause him or her to cry out which also leads to a breath. During the last trimester of pregnancy, a baby can be seen taking practice breaths, during an ultrasound exam. ( Full Answer )

How can a person with mental illness be forced to take treatment but not a patient who has an organic brain injury?
No one can be forced into treatment. Anyone proved to be a danger to them self or others can be placed on a 48 - 72 hour hold - where they are offered treatment and are able to refuse. Once deemed past the danger point they may be free to leave, depending on the stipulations of the hold. Very occa…sionally the courts (along with appropriate medical advisors) will order someone to be held until they are well enough to function in society. This is rarely granted due to our Civil Rights. ( Full Answer )

Your volume increases, but your mass doesn't increase significantly. Try swimming: after inhaling, it is easy to float; after exhaling, you tend to sink.
We first try to give the person oxygen. Keep the person in straight position, then blow air in his/her mouth or nose & push in his/her chest.Then you immediately call a doctor.
By themselves - they can't. But these days we have machines and contraptions that help us with that. Diving gear, diving bells, submarines etc all allow people to breathe underwater.
No human being can breathe underwater unless they obtain gills. We are not able to draw in oxygen from H2O.
yes. but if you hold your breath for longer underwater you can eventually hold your breath for longer everytime due to endurance
you inhale through your nose for as long as you can hold it, then you exhale through your mouth taking out all the air. do it several times and you will feel a bit calmer
Ventilation occurs under the control of the autonomic nervous system from parts of the brain stem, the medulla oblongata and the pons. This area of the brain forms the respiration regulatory center, a series of interconnected brain cells within the lower and middle brain stem which coordinate respir…atory movements. The sections are the pneumotaxic center, theapneustic center, and the dorsal and ventral respiratory groups. This section is especially sensitive during infancy, and the neurons can be destroyed if the infant is dropped and/or shaken violently. The result can be death due to "shaken baby syndrome". ( Full Answer )
Like I don't even want to know why you want to know this but yes they can, if they can fit. Now how long before they hyperventilate? That's something you should really care about, Ted Bundy.
Yes. In order for anything massive to accelerate, a force must be exerted. Your lungs have mass, and go from being stationery, to moving at a more or less steady speed, to stationery and then back again. The accelerate throughout this process and thereby experience a force.
They take 70-90 a minute so multiply 70 well i would do 80 cause the middle number between 70-90 is 80 x 60 which equals 4800 and if you sleep 8 hours you breath about 38400 times a night cause you multiply 4800 by 8 and it = 38400 .
because it comes automatic . Breathing is partially controlled by the voluntary nervous system and partially controlled by the autonomic nervous system. While the voluntary nervous system can hold your breath for a period of time (I have been able to do a bit over 3 minutes), the autonomic… nervous system eventually kicks in and forces you to breath. When you aren't thinking about breathing, the autonomic nervous system automatically keeps you breathing at a fixed rate needed to keep blood oxygen levels adequate for your current level of exertion. This is an automatic feedback system. ( Full Answer )
The obvious force is gravity. This is the effect of space-time being warped by the mass of the earth, but it is more simply what pulls us towards the ground. Then there is the force of air resistance or drag which increases with downward speed to a point where it balances the gravitational pull. The…re is also another force, centrifugal force which tends to act at right angles away from a spinning body. If you intentionally spin in freefall, you can feel a tingling in your fingers and toes as the blood rushes outwards. This is the effect of centrifugal force.

the phenomenon of breathing is absent in plants as plants do not have lungs. However, the gaseous exchange through stomata and lenticel provide oxygen for respiration. During day time oxygen is available to the plants from the process of photosynthesis.
The stethoscope is used to listen to breath sounds in order to findserious lung / chest disorders. Depending on the sound it canindicate a number of illnesses. The 4 main sounds are: Rhonchi - This basically sounds like a "snoring sound" Rales - Described as clicking, rattling or bubbling. Wheezing …- sort of a high pitched whistling noise Stridor - harsh vibratory sound Rhonchi occurs when the airway is obstructed Rales will occur when air opens up spaces that are normally closedto airflow Wheezing can indicate an inflamed and/or narrowed airway such asbronchial tube Stridor occurs when the trachea has a blockage ( Full Answer )
