The patient learns there are healthy bacteria in the bowel that aids in digestion and asks the nurse why bacterium doesn't get into the bloodstream. The nurse described what barrier to answer the patient's question?
A) The mononuclear phagocyte system
B) The portal system
C) The omenta
D) The vomiting reflex
C
Feedback:
The greater and lesser omenta hang from the stomach over the lower GI tract and are full of lymph nodes, lymphocytes, monocytes, and other components of the mononuclear phagocyte system. This barrier provides rapid protection for the rest of the body if any of the bacteria or other foreign agents in the GI tract should be absorbed into the body. Other options do not serve as barriers.
