What are the three phases of breathing?
The three phases of breathing are:The Active phase which is known as (inhalation/ inspiration).Phase 2. gas exchange in the lungs also known as (Internal exchange).The Passive phase which is known as (exhalation /expiration).
Do the muscles function in passive exhalation or active inhalation?
Passive means passive - no muscle action is necessary. You must use your muscles to inhale ... and you can use them to speed up exhalation.
Why does inhalation require more energy than exhalation?
Inhalation requires the contraction of the diaphragm, which takes ATP. Exhalation is simply the passive relaxation of that muscle, in which the atmospheric pressure causes the lung to deflate, taking no ATP.
What step in ventilation requires muscle work?
The inhalation phase. During the inhalation phase, the diaphragm contracts and this requires energy expenditure. The exhalation phase, on the other hand, only involves passive muscle recoil of the diaphragm and does not require work or energy.
When you breathe in and out when do your lungs expend?
on inhalation (breathing in) the main muscles used in respiration at rest are the diaphragm at the base of the chest and external intercostals between the ribs. On inhalation the muscles move the ribs and sternum to expand the chest stretching the lungs as they fill with air. On exhalation (breathing out) which is mainly passive -the enlarged lungs recoil and shrink as the intercostals and diaphragm relax. Abdominal pressure pushing the diaphragm upwards to actively compress the lungs back to their resting volume.
Why does it hurt when you breathe out and not in?
Depends on the cause of the pain, but if the pain is from overexertion from intense physical activity, may be due to the muscles involved in respiration. The intercostal muscles between the ribs, and diaphragmatic muscles, both expand and are placed under greater stress during inhalation. Upon exhalation, the release of air allows these muscles to relax without effort, being usually a passive part of the breathing cycle.
What are the active and passive parts of breathing?
passive process
What is the official name for secondhand smoke?
air pollution Passive smoking or passive inhalation.
What is meant by residual volume with reference of breathing?
Exhalation is a passive action that results from elastic recoil and changes in air pressure. When this happens naturally a portion of air remains within the lungs- residual volume. However when exhalation is forced, that is conscious efforts to expel as much air as possible, many of the residual volume can be forced out of the lungs.

What are active and passive smokers?
Active is actually smoking. Passive is standing near active, and breathing in their smoke, indirectly.
What muscle moves down when you inhale and up when you exhale?
During passive breathing the diaphragm moves down for inhalation this pushes the organs of the abdomen down and so pushes the rectus abdominus out, this is why you see your abdomen moving. To assist exhalation the rectus abbominus then contracts pushing the organs back in and so pushing hte diaphrag pack up.
