Thanks for the feedback!
yes. women breath 18 times/min and man 16/min
Children learn faster than adults because their brain is literally growing in size faster, the human brain typically grows until someone turns about 22, but as you age everyth…ing in your body grows at a slower rate.
Infants have faster heartbeats than adults for two reasons. Like most small animals, because they have so much skin for less volume, they lose heat much faster than adults…. As well, infants are growing at astounding rates, and this requires extreme amounts of metabolism to keep up. First, note that it doesn't always. Reasons: Children have higher metabolic rates than adults. Children's hearts are smaller, thus the amount of blood expelled by each beat is less. (Note that the heart rate is "ideally" controlled by the total oxygen required by the body.)
The short answer: The elevated heart rate is required to support the baby's rapid growth. Some Detail Fetal development is dependent upon adequate exchange of gases a…nd nutrients within the placenta. FHR (fetal heart rate) is generally about twice as high as the typical adult resting heart rate in order to support the high nutrient and gas exchange levels as well as the disposal of metabolic waste required for proper fetal development. Typical FHR in a fetus of 20 weeks averages about 155 beats per minute, with the normal range falling between 120 and 180. By term that rate has decreased, averaging 140 within a typical range of 120 to 160. By contrast, a healthy adult typically has a resting heart rate of about 80. Unusually low FHR can cause fetal acidemia, fetal acidosis and other fetal acid-base physiological problems. These, in turn often result in impaired fetal metabolism and impaired development. Throughout a person's life, typical heart rate can be seen to closely parallel rate of growth, steadily declining with the decline of growth in the mid-teens: Fetal - 20 weeks - 120-180 Fetal - term - 120-160 Infancy - 120-160 12-35 months - 80-110 3-5 years - 70-110 6-12 years - 65-110 13-18 years - 60-90 19-61 years - 60-100* *Cardio-vascular diseases account for the increased heart rates of older individuals.
because their hearts beat faster
their bodies tell them that they need more oxygen and so breathe faster to try and get the oxygen their body requires and depends on.
because they have less alveoli
yes dogs breath faster then human because they always have there mouth open so im guessing they do humans only breath like around every second they dont always have there mout…hes open like a dog.
A dog's normal respiratory rate is 18-34 breaths per minute. An adult human's rate is 12-20 breaths per minute.
it depends on if your obese (which you probably are).. so yea
Cause their heart beat is faster than humans
its probably uncomfortable or maybe its sick dont always believe wiki answers i am not giving good info.
because their lungs are smaller and they have more organs to pump blood through
Children have smaller lungs therefore less time is required to fill them with air.
Any small animal's metabolic rate is higher/faster than the larger/bigger ones. And breathing is positively correlated with metabolism. Thus small fish breath faster than larg…e fish.
Kids breathe faster because their lungs are smaller and are softer so they need more air and go really fast for the air like when they run too fast and are out of breath!
