It can be classified under the umbrella term chronic obstructive pulmonary disorder (COPD) . Cigarette-associated noxious agents injure the airway epithelium and drive the key processes that lead to specific airway inflammation and structural changes [].Once these agents are removed, repair processes should, ideally, bring the airways back to their normal structure and function. Documents Similar To COPD PATHOPHYSIOLOGY diagram. Creately diagrams can be exported and added to Word, PPT (powerpoint), Excel, Visio or any other document. Through programmed cell death (apoptosis), recycling of the cell components (autophagy) or cellular necrosis, there is a loss of alveolar cells and surface area resulting in emphysema.13-15 Apoptosis not only results in the phagocytosis of cell fragments, but also in the release of damage-associated molecular patterns that are pro-inflammatory. 2010;184(3):1575-1588. doi: http://dx.doi.org/10.4049/jimmunol.0900290.

It is critical to understand these pathways as we attempt to understand disease susceptibility in target populations. And when the disease continues to worsen, Hypercapnia (high CO2 in the blood) occurs and leading to Respiratory Acidosis. Chronic obstructive pulmonary disease (COPD) is a serious and chronic lung condition that affects breathing. This is a set of diseases where the flow of air in the lungs is obstructed. Bronchitis Pathophysiology - Infections, or Irritants like tobacco smoke, impose functional changes within the respiratory airways. Retamales I, Elliott WM, Meshi B, et al.

Neutrophil elastase contributes to cigarette smoke-induced emphysema in mice. Particularly, if the alveolar walls keep breaking down, the pulmonary capillary bed will become smaller. Emphysema gets worse over time, and it affects everyone differently. Such … In patients with chronic obstructive pulmonary disease (COPD), pro-inflammatory and pro-destructive pathways are activated, at times independent of smoke exposure, and other anti-inflammatory, anti-oxidant, or repair pathways are down-regulated, all resulting in lung destruction.

RTP801 is required for ceramide-induced cell-specific death in the murine lung. It's caused by long-term exposure to irritating gases or particulate matter, most often from cigarette smoke. This results to the air flow obstruction. In addition to macrophages and neutrophils, B cells contribute to COPD development through the generation of lymphoid follicles within the parenchyma of patients with COPD.
