when you inhale..(take in oxygen)..the air fills up the lungs, the ribcage expands and the muscle sheet called the diaphragm pushes downward and flattens as you inhale ..whn you ehale the muscle returns back to domed-shape

What structure lines the medullary cavity?
endosteum
Which structure contain the nasopharyngeal with the tympanic cavity?
Tympanic membrane
What is the name of the skeletal structure which surrounds the chest cavity?
Ribs
What is a structure through which air passes when inhaling?
Sinus cavity
How is intrapleural pressure maintained?
Intrapleural pressure is the pressure difference between the lungs and the pleural cavity of the lungs.
What makes move into and out of the lungs?
Pulmonary ventilation or breathing has two phases. Inspiration or inhalation moves air into the lungs and expiration or exhalation moves air out of the lungs. The lungs are enclosed within the thoracic cavity. Thus changes in the shape and size of the thoracic cavity result in changes in the air pressure within that cavity and in the lungs. This difference in air pressure causes the movement of air into the lungs. Air moves from an area where pressure is high to an area where pressure is low. Respiratory muscles are responsible for the changes in the shape of the thoracic cavity that cause the air movements involved in breathing.The abdominal diaphragm is (or should be) the major muscle driving respiration.Source(s):Structure and function of the body

What causes a pressure chage in the chest cavity during breathing?
The movement of the rib cage changes the air pressure in the chest cavity depending on the physical activity the person is performing. If they are running, the air pressure will be constantly increasing and decreasing, leading to stress on the rib cage.
Which describes the action of the diaphragm and chest cavity when you exhale and squeeze air from the lungs?
it will changes the air pressure in the thoratic cavity by increasing or decreasing the thoratic volume
What muscular structure separates the thoracic and abdominopelvic cavity?
The diaphragm separates the abdominal from the thoracic cavity.
What is abdominal cavity What structure separates it from the thoracic cavity?
Diaphragm
What structure separates the thoracic cavity from the abdominal cavity?
The diaphragm
Which structure separates the thoracic cavity from the abdominal cavity?
Diaphragm
What cavity contains the lungs and what structure divides it from the abdominal cavity?
The lungs and heart are found in the thoracic cavity and that cavity is superior to the diaphragm.
What structure separates the cranial cavity and thoracic cavity?
The cervical spine, or the neck.
What structure divides the thoracic cavity into right and left hemithorax?
chest cavity
What structure lines the medullary cavity?
endosteum
