There are four sets of muscles that control the respiratory system:
- The Diaphragm
- The Intercostal Muscles
- The Abdominal Muscles, and
- The Accessory Muscles

∙ 15y agoIt'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.

∙ 13y agoThe 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.]

Structure of muscle?
the sacromere, contains two kinds of filaments.
What tissue is a skeletal muscle?
skeletal muscle is just a form of muscle that is striated. The other two kinds are cardiac and smooth. It is just muscle tissue.
What are two kinds of problems for your muscles?
Muscle pain and broken bones
What are two kinds of muscle tissues?
Two types of muscle in the human body are striated muscle. Striated means "striped" and is the type of muscle that moves the body. Smooth muscle does not have the striped appearance and is not under conscious control.
What is the quickness of muscle called?
I think you are thinking of fast twitch muscles. There are two kinds fast twitch and slow twitch.
What muscle helps with food digestion and breathing?
Previous answer: "involuntary muscles"This answer is not accurate. While breathing muscles do act involuntarily, they can also be activated voluntarily. The two primary muscles responsible for breathing are the diaphragm and the tranversus abdominus. The diaphragm is the primary muscle for inhalation, if you're breathing correctly. The transverse is the primary muscle for forced exhalation.Since both muscle, when contracting, move inward into the abdominal cavity, where your organs of digestion are, they move the internal organs, essentially creating an internal massage mechanism for the large and small intestines, which helps keep smooth motion going in the involuntary pyloric (intestinal) muscles.
How many muscles does it take to blink?
It is not clear exactly how many muscles it takes to blink. Some of the muscles that are involved in the blinking process include orbicularis oculi and the levator palpebrae superioris muscle.
What muscle to you stretch when touching your toes?
The muscle that forms the calf of your lower leg is the muscle that helps you lift to your toes. This muscle is called the gastrocnemius.
What are the two phases of breathing?
The two phases of breathing are breathing in and breathing out. Humans breathe in oxygen and they release carbon dioxide when they breathe out.
What are the two kinds of xylem and their functions?
1. Centripetal xylem 2. Centrifugal xylem both types are involved in conduction
What are the two primary functions of the cerebellum?
The cerebellum is involved in the coordination of voluntary motor movement, balance and equilibrium and muscle tone.
What is the Large muscle that helps mammals breathe?
The diaphragm is the primary muscle involved with breathing. When you want to take a breath in (inhale) you contract your diaphragm. This makes the thoracic cavity larger, decreasing the pressure in the thoracic cavity and generating a vacuum. Air is drawn into the lungs because of the creation of this intra-thoracic vacuum. When you relax your diaphragm the elasticity of your lungs will force air back out (exhalation).
