Which three components are typically affected in intestinal atresia?

In cases of intestinal atresia, the condition primarily involves a congenital obstruction of the gastrointestinal tract where a segment of the intestine is absent or closed off. This often affects various parts of the digestive system, particularly in neonates.

The correct answer highlights that intestinal atresia can impact the stomach, duodenum, and other sections of the intestine. Specifically, duodenal atresia is one of the more commonly recognized forms, occurring in the first part of the small intestine just beyond the stomach. There can also be atresias affecting the jejunum and ileum, but the implication that other parts of the intestine may also be involved reflects the variable nature of this condition.

In clinical practice, it's important to note that while some forms of atresia are isolated, others can present as part of more complex gastrointestinal anomalies that may involve multiple sections. This is particularly relevant for understanding the spectrum of congenital defects that can arise during embryonic development.

The other options fall short in adequately capturing the breadth of intestinal atresia involvement. For example, while some could mention specific portions like the jejunum and colon, they do not encompass the full range of potential affected areas, which is crucial in understanding the diverse presentations of this condition.
