This failure allows abdominal contents, such as the stomach and intestines, to herniate into the thoracic cavity, leading to lung compression and underdevelopment (hypoplasia). The mechanism involves disruptions in the development of the pleuroperitoneal membranes, which are derived from mesodermal tissue. This results in a defect, most commonly on the left side (Bochdalek hernia). The herniation impedes normal lung expansion, causing respiratory distress at birth. Understanding this mechanism emphasizes the importance of diaphragm integrity for proper thoracic and abdominal compartmentalization, as well as lung development. #USMLE #Step1 #PleuroperitonealmembranesclosingcongenitaldiaphragmaticherniaCDH #MedicalSchool #MedStudent
