Medicine Respiratory disease is a medical term that encompasses pathological conditions affecting the organs and tissues that make gas exchange possible in higher organisms, and includes conditions of the upper respiratory tract, trachea, bronchi, bronchioles, alveoli, pleura and pleural cavity, and the nerves and muscles of breathing.
Upper respiratory tract infection common cold however, sinusitis, tonsillitis,pharyngitis and laryngitis are Lower respiratory tract infection pneumonia, tuberculosis Diagnosis Respiratory diseases may be investigated by performing one or more of the following tests Chest x-ray Pulmonary function test Computed tomography scan Culture of microorganisms from secretions such as sputum Bronchoscopy Biopsy of the lung or pleura Ventilation — perfusion scan Ultrasound scanning Epidemiology Respiratory disease is a common and important cause of illness and death around the world.
The thoracic cavity then returns to its smaller size. Air moves from an area where pressure is high to an area where pressure is lower. Contraction of the abdominal muscles pushes the abdominal organs against the underside of the diaphragm, thus elevating it and making more dome shaped.
They are traditionally divided into upper respiratory tract infections and lower respiratory tract infections. Respiratory muscles are responsible for the changes in the shape of the thoracic cavity that causes the air movements involved in breathing.
Restrictive lung diseases Restrictive lung diseases also known as interstitial lung diseases are a category of respiratory disease characterized by a loss of lung compliance, causing incomplete lung expansion and increased lung stiffness.
Contraction of the inspiratory muscles increases the volume of the thoracic cavity and reduces the air pressure within it, drawing air in the lungs.
Respiratory diseases can be classified in many different ways, including by the organ or tissue involved, by the type and pattern of associated signs and symptoms, or by the cause etiology of the disease. Respiratory tract infections Infections can affect any part of the respiratory system. The result is to further shorten or decrease the top to bottom size of the thoracic cavity.

Muscles of respiration that are classified as inspiratory muscles include the diaphragm it is the dome-shaped muscle seperating the abdominal cavity from the thoracic cavity.
