What are two kinds of muscle involved wth breathing?

Answer 1

There are four sets of muscles that control the respiratory system:

• The Diaphragm
• The Intercostal Muscles
• The Abdominal Muscles, and
• The Accessory Muscles

Answer 2

It's more than two muscles. When you inhale, your diaphragm contract, lowers, and decreases the pressure in the thoracic cavity (where your lungs are), thus causing air to enter the lungs. If you're exercising or having trouble breathing, your intercostal muscles (the ones between your ribs) can also help with this. There are three layers of intercostal muscles pointing in different directions.

When you exhale, the elasticity of your lung alveoli and your chest wall make this an almost passive motion. If you force an exhale more quickly, that uses your abdominal muscles such as the rectus abdominus.

Answer 3

The diaphragm muscles and the intercostal muscles.

When breathing in, the intercostal muscles move the ribcage upwards and outwards and the diaphragm muscles contract to pull the diaphragm downward.

[This creates a difference in pressure within the lungs to that outside (it has a lower pressure). In this way air is sucked in to equal out the pressure. When breathing out, the muscles relax and the volume of the lungs is reduced, pushing out the air.]

Answer 4

diaphram and tracia

Also the rib muscle

Answer 5

Main muscle is diaphragm. Also intercostal muscles are important

Answer 6

Internal and external intercostals. Internal intercostals control exhalation, external intercostals control inhalation.
