2. Which muscles are involved in breathing and how they work?
Answers
Explanation:
The diaphragm is the main muscle used for breathing. The muscles between your ribs, called intercostal muscles, play a role in breathing during physical activity. Abdominal muscles help you breathe out when you are breathing fast, such as during physical activity. Muscles of the face, mouth, and pharynx.
Explanation:
diaphragm is the major muscle responsible for breathing. It is a thin, dome-shaped muscle that separates the abdominal cavity from the thoracic cavity. During inhalation, the diaphragm contracts, so that its center moves caudally (downward) and its edges move cranially (upward). Your lungs are a pair of organs in your chest.They have a spongy texture and are pinkish-gray in color.
When you inhale (breathe in), air enters your lungs and oxygen from the air moves from your lungs to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathe out). This process is called gas exchange and is essential to life.
In addition to the lungs, your respiratory system includes the trachea (windpipe), muscles of the chest wall and diaphragm, blood vessels, and tissues that make breathing and gas exchange possible. Your brain controls your breathing rate (how fast or slow you breathe), by sensing your body’s need for oxygen and its need to get rid of carbon dioxide.
Healthy lifestyle habits, such as physical activity and not smoking, can help prevent lung injury and disease.
