The same kind of thin tissue lines the inside of the chest cavity -- also called pleura. The upper most portion of each lung is called the apex and the inferior most portion is called the base. The lungs are covered by a thin tissue layer called the pleura.

The lungs are roughly cone shaped with an apex base three surfaces and three borders. The lungs are very important in the respiratory system Each lung contains a bronchus which is divided into bronchioles The bronchioles end in tiny air sacs called the alveoli that are surrounded by networks of blood capillaries.

In addition to this there is a framework of interstitial or fibrous tissue in which are found the blood vessels and lymphatics. See lung structure stock video clips. Lungs Humans have a pair of lungs which are sac-like structures and covered by a double-layered membrane known as pleura.

These are called lobes and they are separated from each other by connective tissues.

The outer membrane of this structure is called parietal pleura and is attached to the chest wall whereas the inner membrane is called the visceral pleura and it covers the lungs as well as the associated structures. Vector illustration of lung drawing. The lungs are a couple of light air-filled organs situated on either side of the chest thorax.

The median surfaces of the lungs lie next to the mediastinum. Texture-- Spongy Color Young brown Adults -- mottled black due to deposition of carbon particles Weight-Right lung - 600 gms Left lung - 550 gms. The lungs are covered by a protective membrane known as the pleura.
