Being overweight increases the mass of tissue that has to be moved by the inhaled air as the diaphragm pulls down. This can make it harder to breathe and at the same time limits the volume of air that enters. So one must breathe faster to get the same amount of oxygen, even as the greater mass of the body requires even more oxygen. So generally, breathing rate goes up with additional weight.
yes . . depending on availability of oxygen, breathing rate changes
yes, it will
Yes it does.
yes
Carbon dioxide
No. What you may be thinking of is aerobic respiration (normal breathing), for which the breathing rate (as well as heart rate) is typically a bit slower in men.
exercise and weight
Yes
The smaller the size of a tropical fish the faster their breathing rate will be. The smallest fish will have the fastest breathing rates.
they both are related by age, size, weight, activity level , and heath.
The breathing rate and pulse rate are related proportionally. If the breathing rate increases, so does the pulse rate. The pulse rate is an indication of the breathing rate.
Yes the altitude of the area does affect the breathing rate becaue the higher you go the lower the air pressure and the the lower you go the lower the air pressure.
