Lab 5 Questions

What was the question I said in the respiratory lecture would be part of this week's assessment?

What is Congenital Diaphragmatic Hernia and how does it affect the human lungs?


What is the answer to the above question?

Congenital means born with and a hernia is a problem where something goes through a hole it is not supposed to. The hole is in your baby's diaphragm. The diaphragm is a muscle that helps us to breathe and keeps the organs in the abdomen from going into the chest cavity In your baby's case, the hole stayed open. This allowed some of the intestines to go into the chest cavity. Since the intestines were in the chest cavity and not where they were supposed to be, the lungs could not grow in the normal space that they need (they had to share the space with the intestines). This means that the lungs are smaller than they should be.
