Because it is much smaller than an adult heart. The smaller the heart the faster it beats. The heart of a marathon runner for example, which has grown through the training may only beat at 35 -40 when asleep. It's important to remember that a baby also breathes faster. This is because a baby's lungs are not fully developed. A baby's lungs have decreased alveolar surface area, which is essential for air exchange with the blood. There is also increased anatomical dead space where air taken in can not be made available for air exchange. For these reasons, the baby must breathe faster to move more air in and out of his lungs in order to make enough oxygen available to the relatively few alveoli. The oxygen is absorbed into the blood cells, which must move quickly through the baby's developing lungs, so that more blood can absorb oxygen. Thus, the baby's heart must beat much faster to make enough deoxygenated blood available for gas exchange in the developing lungs.
What else can I help you with?
Why is the breathing rate of adults is different from children?
Because they have a higher metabolism rate and a faster heartbeat. It is also possible that the lungs are not as efficient since they are still growing.

Why do women and children have faster breathing rate?
smaller lungs
What breathing faster mean in newborn?
Newborns breathe at a much faster rate than adults and even older children. Normal adults take about 12-20 breaths per minute. Most newborns take between 40 and 60 breaths per minute. So if the newborn is breathing faster than adults, that's no cause for concern. But if she is breathing significantly faster than other newborns, then there may be something going on that needs medical attention.
What causes increased respiratry rate in children?
Children are growing at faster rate. They need more oxygen for the increased metabolic activities. So the heart rate as well as the respiratory rate of children is higher as compared to adults.
What is the average breathing rate for adults during exercise?
The average breathing rate of adults during exercise is 40 to 50 breath per minute.
Whose heart rate is faster kids or adults?
Kids heart rate is faster.
Why is a child's heart beat much faster than an adults?
As you age, your heart rate declines. Also, children usually have more energy than adults.
Do children lose weight faster than adults?
Ultimately, it depends on the diet. If you're overeating you won't lose weight even if you are a kid. When we have low metabolism rate, body cannot burn more calories, high metabolism helps us to burn more calories. Children have fast metabolism rate when we compared to adults and teenagers. That is the reason children lose weight faster than adults.
Is the breathing rate of children different from adult?
Because they have a higher metabolism rate and a faster heartbeat. It is also possible that the lungs are not as efficient since they are still growing.
Do teens have a faster heart rate or adults?
yes
Who has the fastest heart rate children or adults?
children
