(Source google.com)
The lungs are a pair of spongy,
air-filled organs located on either side of the chest (thorax). The trachea
(windpipe) conducts inhaled air into the lungs through its tubular branches,
called bronchi. The bronchi then divide into smaller and smaller branches
(bronchioles), finally becoming microscopic. The bronchioles eventually end in
clusters of microscopic air sacs called alveoli. In the alveoli, oxygen from
the air is absorbed into the blood. Carbon dioxide, a waste product of
metabolism, travels from the blood to the alveoli, where it can be exhaled. The progression of air through either the mouth or the nose, travels through the nasopharynx, oropharynx, larynx, and the trachea (windpipe). The air passes down the trachea, which divides into two main bronchi; these branch to the left and right lungs where they progressively subdivide into a system of bronchi and bronchioles until the alveoli are reached. These many alveoli are where the gas exchange of carbon dioxideand oxygen takes place. Breathing is driven by muscular action; in early tetrapods, air was driven into the lungs by thepharyngeal muscles via buccal pumping, which is still found in amphibians. Reptiles, birdsand mammals use their musculoskeletal system to support and foster breathing. Medical terms related to the lung often begin with pulmo-, such as in the (adjectival form:pulmonary) or from the Latin pulmonarius ("of the lungs"), Between the alveoli is a thin layer of cells called the interstitium, which
contains blood vessels and cells that help support the alveoli. The lung is the
essential respiration organ in many air-breathing animals, including
mosttetrapods, a few fish and a few snails. In mammals and the more complex
life forms, the two lungs are located near the backbone on either side of the
heart. Their principal function is to transport oxygen from the atmosphere into
the bloodstream, and to release carbon dioxidefrom the bloodstream into the
atmosphere. A large surface area is needed for this exchange of gases which is
accomplished by the mosaic of specialized cells that form millions of tiny,
exceptionally thin-walled air sacs called alveoli.
To understand the anatomy of the
lungs, the passage of air through the nose and mouth to the alveoli must be
studied. The progression of air through either the mouth or the nose, travels
through the nasopharynx, oropharynx, larynx, and the trachea (windpipe). The
air passes down the trachea, which divides into two main bronchi; these branch
to the left and right lungs where they progressively subdivide into a system of

"lung"). The lungs are covered by a thin tissue layer called the
pleura. The same kind of thin tissue lines the inside of the chest cavity --
also called pleura. A thin layer of fluid acts as a lubricant allowing the
lungs to slip smoothly as they expand and contract with each breath.
