The oropharynx, nose, larynx, bronchi, trachea, bronchioles, and lungs make up the majority of your respiratory system to maintain the function of the lungs. The lungs are further subdivided into separate lobes, which are further subdivided into more than 300 million alveoli. The principal site ...
The process of exchanging gases (carbon dioxide for oxygen) occurs at the lung alveoli. Alveoli are coated with a moist film that dissolves air in the lungs. Oxygen diffuses across the thin epithelium of the alveoli sacs into the blood within the surrounding capillaries. Carbon dioxide also dif...
As the title suggests, most of the chapters concern anatomy, embryology, connective tissue and lymphatics, cartilage, mucus-secreting elements, perinatal circulation, postnatal development of alveoli, pulmonary circulation...
Our lungs receive air from the external environment through the process of negative pressure breathing. Negative pressure breathing requires a pressure differential between the air inside the alveoli and atmospheric air. Muscles surrounding the lungs, such as the diaphragm, intercostal muscles, and abdomi...
Lungs: Anatomy Lungs are the main organs of the respiratory system. Lungs are paired viscera located in the thoracic cavity and are composed of spongy tissue. The primary function of the lungs is to oxygenate blood and eliminate CO2. To perform this function, the lungs need to be able to ...
The lungs supply oxygen to the rest of the body and remove carbon dioxide. The lungs are made up of millions of tiny air sacs called alveoli. Oxygen passes through the walls of these air sacs and is absorbed into the bloodstream. Carbon dioxide passes ou

Structure of the Alveoli Alveoli are the smallest structures in the respiratory system. They are arranged in clusters throughout the lungs at the ends of the passageways that bring air into the lungs (respiratory tree). The walls of the alveoli are very thin, which makes it easier for oxygen...
