The normal kind that all animals breathe; a mixture of nitrogen, oxygen, argon carbon dioxide and trace amounts of other gases.
The air they breath is the same air that you breath; the atmosphere of the planet Earth.
The most common use of the respiratory system is the exchange of gases. When you exhale carbon dioxide, at the same time you inhale oxygen.
Your lungs circulate oxygen every time you inhale and exhale. They travel through your body when you inhale to the lungs and the lungs store the oxygen, and as you exhale, carbon dioxide from the air is released.
Much like as in a concertina or a piano accordian. Body muscles increase the volume of the chest, and air rushes in to occupy the extra space. Then the body muscles reduce the volume and to avoid being pressurised the air is pushed out.
Speech is normally produced by the intermittent release of expired air and the opening and closing of the glottis (the gap between the vocal cords). However, speech can also be produced by the intermittent retention of air inspired through the mouth. This special technique has been used in Kryia Yoga.
yes sssssssssssssssoooooooooooooooooooooooooo easyyyyyyyyyyyyyyyyyyyyyyyy
Yes, in the sense that it can (and will in time) kill you ... slowly and uncomfortably. What it is is the loss of elastin in the terminal airways. What it does to you is that it allows you to inhale, but not exhale. You adjust by getting a bigger chest, but there is an upper limit to that.
When you exhale and fart at the same time
Strengths of the model: shows accurate organs and inhale and and exhale. Limitations: cant adjust to human conditions, doesn't show change over time.
Water is taken in and utilized by plants for photosynthesis.
In day time trees inhale carbon dioxide and exhale oxygen, making it available in more amount in the park. While at night time, they do the reverse. so the air in day time in the park is more fresh than at night time.
stealthily and clumsily at the same time
It can have from two to 9 period...
