Respiratory System

Pneumothorax is a condition where air enters the pleural cavity, leading to lung collapse.

The larynx provides a patent airway, routes food and air into correct channels, and produces voice.

Gas exchange occurs primarily in the alveoli.

Asthma is a common respiratory disorder characterized by inflamed airways and difficulty breathing.

Air passes through the nose, nasal vestibule, nasal conchae, nasopharynx, oropharynx, laryngopharynx, and trachea.

Alveoli are tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide occurs.

Pleurisy is inflammation of the pleura, the membranes surrounding the lungs, causing sharp chest pain.

The trachea, or windpipe, provides a clear airway for air to enter and exit the lungs.

Bronchi are the main passageways that branch from the trachea into the lungs.

The conducting zone includes structures that transport air (like the trachea and bronchi), while the respiratory zone is where gas exchange occurs (like the alveoli).
