Croup

Viral croup; Laryngotracheobronchitis - acute; Spasmodic croup; Barking cough - croup

Croup is breathing difficulty and a "barking" cough. Croup is due to swelling around the vocal cords. It is common in infants and children.

Lungs

The major features of the lungs include the bronchi, the bronchioles and the alveoli. The alveoli are the microscopic blood vessel-lined sacks in which oxygen and carbon dioxide gas are exchanged.

Throat anatomy

Structures of the throat include the esophagus, trachea, epiglottis and tonsils.

Voice box

The larynx, or voice box, is located in the neck and performs several important functions in the body. The larynx is involved in swallowing, breathing, and voice production. Sound is produced when the air which passes through the vocal cords causes them to vibrate and create sound waves in the pharynx, nose and mouth. The pitch of sound is determined by the amount of tension on the vocal folds.
