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.
The ribs expand during inhalation. This creates negative pressure on the lungs and draws air into them. During exhalation the rib cage gets smaller, compressing the lungs, in a sense, and forcing air out.
Ribs are bones, but lungs contribute to breathing and they are a muscle organNo, your Lungs ARE NOT A MUSCLE. Your diaphragm is the main muscle in inhalation, which opens your lungs (works by creating a negative pressure in your lungs i.e. the pressure outside your chest cavity is more than the pressure in your lungs, causing air to enter your lungs).However, during forced inhalation and exhalation your intercostal muscles and rectus abdominus muslces play a part in exhalation (forcing air out). scalenes lift up your rib cage to allow maximum inhalation.
Presence of redness or swelling,especially over 5 mm (1/4 inch.indicates an allergic response.Following allergen inhalation, reduction in exhalation capacity of more than 20%,and for at least 10-20 minutes.Gastrointestinal symptoms within 24 hours.
When you exhale, pressure increases in the lungs to cause exhalation- this also further constricts the bronchioles, however, making it harder to exhale. The pressure decreases again for inhalation, relieving the bronchioles andmaking it easier for the air to flow again. This is why wheezing is usually worse during exhalation.
This is called sinus arrhythmia. It is a normal phenomenon where the heart rate increases during inhalation and decreases during exhalation. It is more commonly seen in younger individuals and can be a normal finding.
no it relly does not
The diaphragm moves down to make the lungs expand (inhalation)
Simply put because mammalian cells require more sustained energy.
They require more energy then single-celled organisms
If you take energy in the form of heat, from water it will freeze and so is not water any more.
Muscle cells, especially those found in the heart and skeletal muscles, require a significant amount of energy to perform their functions. Therefore, they would need to have more mitochondria to meet their high energy demands.
by eating more and hunting and that gives you the ability to work.that makes the energy for the cheetah or what every animal need is energy.
