Blood Supply The major function of the lungs is to perform gas exchange, which requires blood from the pulmonary circulation. This blood supply contains deoxygenated blood and travels to the lungs where erythrocytes, also known as red blood cells, pick up oxygen to be transported to tissues throughout the body.

The lungs' main role is to deliver oxygen to the blood and remove carbon dioxide from the blood. Air enters the nose or mouth and passes through your windpipe and into the bronchial tubes when you breathe in. The bronchial tubes lead into the lungs and branch out into smaller tubes known as bronchioles, which end in small air sacs known as alveoli.

Anatomy Function Associated Conditions Tests The lungs are a major organ that is part of the respiratory system, taking in fresh air and getting rid of old, stale air. This mechanism of breathing also helps to allow you to talk. By taking in fresh air, the lungs are able to help oxygenate blood to be carried around your body.

Blood supply. The lungs have dual, parallel blood supply referred to as pulmonary and systemic circuits. The pulmonary circuit arises from the heart and brings deoxygenated blood to the lung for gas exchange. This circuit also takes oxygenated blood back to the heart to be redistributed to the rest of the body.

The respiratory system, also called the pulmonary system, consists of several organs that function as a whole to oxygenate the body through the process of respiration (breathing). This process involves inhaling air and conducting it to the lungs where gas exchange occurs, in which oxygen is extracted from the air, and carbon dioxide expelled.

The superior end of the lungs narrows to a rounded tip known as the apex. The inferior end of the lungs, known as the base, rests on the dome-shaped diaphragm. The base of the lungs is concave to follow the contour of the diaphragm. The left lung is slightly smaller than the right lung because 2/3 of the heart is located on the left side of the.

Functionally, the lung is divided into a series of bronchopulmonary segments. The bronchopulmonary segments are the largest subdivision of a lobe. They are separated from adjacent segments by connective tissue septa and are also surgically resectable. They are 10 bronchopulmonary segments in the left lung and 8-10 in the left lung [9].
