Final answer:
Necrotizing enterocolitis (NEC) is linked to premature birth and underdeveloped gastrointestinal systems, manifesting as abdominal issues and potentially leading to severe tissue damage due to hypoxia.
Step-by-step explanation:
Necrotizing enterocolitis (NEC) results from premature birth and immature gastrointestinal development and is manifested by abdominal distension and discoloration of the abdomen. Ischemia/hypoxia results in decreased oxygen delivery to tissues and potential cell death. This condition is primarily associated with underdeveloped intestines in premature infants, leading to impaired blood flow and subsequent organ dysfunction. The lack of oxygen and nutrients to tissues can cause severe tissue damage and various gastrointestinal complications.
