Gurgling sounds heard as air passing through moist secretions in the respiratory tract.

Inside the cheek or mouth, or the gum beside the cheek.

Enveloped viruses bud though the cell membrane of infected cells acquiring the membrane as the base of its envelope. Major viral matrix proteins hemagglutinin and neuraminidase poke though the envelope and carry it with them enveloped around the capsid (protein body). An infected cells will typically assemble thousands of viruses, the membrane will slowly be depleted and the cell will die.

The small airways of the lung extending from the bronchi to the alveoli.

A combination of substances in aqueous solution that resists changes in hydrogen ion concentration when a strong acid or a strong base is added to the mixture.

BAL; a flexible catheter is placed in the suspect area of the lung. Saline is then released into the area and drawn back through the catheter to be used as a test sample to aid in diagnosing infection/pneumonia; may be performed by a camera (requires equipment, pulmonologist and technician) or blind (small, mini catheter) by a trained respiratory therapist or nurse.

A fluid filled blister more than 5mm in diameter with thin walls. A bulla on the skin is a blister; a bulla within the tissues is more often referred to as a bleb (e.g. on the pleura – the membrane covering the lung.
