When the lungs inhale, the diaphragm contracts and pulls downward. At the same time, the muscles between the ribs contract and pull upward. This increases the size of the thoracic cavity and decreases the pressure inside. As a result, air rushes in and fills the lungs.
What is the thoracic cage?
The thoracic cage (rib cage) forms the thorax (chest) portion of the body. It consists of the 12 pairs of ribs with their costal cartilages and the sternum ((Figure)). The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1–T12). The thoracic cage protects the heart and lungs.
What is thoracic hypoplasia?
ATD is characterized by abnormal development of the rib cage (thorax) resulting in a small thoracic cavity. The characteristic “bell-shaped” chest cavity restricts the growth of the lungs and results in a variable degree of lung hypoplasia and breathing problems (respiratory distress) in the newborn period.
What does thoracic nerve pain feel like?

What will happen if your rib cage move downward?
The rib cage is moved downward and inward resulting in reduced volume of the thoracic cavity. Consequently, the intra- pulmonary pressure goes above the atmospheric pressure and the air rushes out. This is how expiration takes place. Hence the correct answer is option C.
Why is my rib cage getting bigger?
Body Fat Distribution Abdominal fat often increases with age, due at least in part to age-related muscle loss, according to Harvard Health. Inactivity can accelerate this process. Abdominal fat increases the size of your torso and rib cage.

Is thoracic pain serious?

What happens when you breath in and out?
When you inhale (breathe in), air enters your lungs, and oxygen from that air moves to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathed out). This process, called gas exchange, is essential to life.
Will losing weight make my ribcage smaller?
Your body fat and muscle affect your circumference at the ribcage. Yes, your rib cage can become smaller when you lose weight. This occurs due to losing subcutaneous fat, the layer of fat directly below the skin. Weight gain results from consuming more calories than you use in activity.
