WebMay 7, 2024 · The left lung is smaller and contains only two lobes. The smaller left lung allows room for the heart, which is just left of the center of the chest. Lung tissue consists mainly of alveoli (Figure \(\PageIndex{6}\)). These tiny air sacs are the functional units of the lungs where gas exchange takes place.

WebGas exchange occurs in microscopic dead-end air-filled sacs called alveoli, where a very thin membrane (called the blood-air barrier) separates the blood in the alveolar capillaries (in the walls of the alveoli) from the alveolar air in the sacs. Exchange membrane [ edit] Fig. 4. WebThe accumulated fluid in the alveoli and airwayscauses lung stiffness, makes lung expansion more difficult, and impairsthe gas exchange function of the lung. With the decreased ability ofthe lungs to oxygenate the blood, the hemoglobin leaves thepulmonary circulation without being fully oxygenated, resulting inshortness of breath and cyanosis.
WebGas Exchange - May 04 2024 Experiments with a Numerically Impaired Lung - May 24 2024 In some lung diseases, airways and alveoli collapse and may not reopen for a sig nificant portion of inhalation. This leads to impaired gas exchange, and could r esult in lung failure. The current thesis is the outcome of our initial WebGas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration.
