Quizplus · Accepted Answer

Congenital megacolon, also known as Hirschsprung's disease, involves a problem with the innervation of the large intestine and colon, not the blood vessels. The other options all involve problems with blood vessels in some way. Mass reflex reaction refers to the sudden and exaggerated response of the sympathetic division to a stimulus, often resulting in changes in blood pressure and heart rate. Raynaud's disease is a disorder of the blood vessels that causes narrowing and spasms in response to cold or stress. Hypertension is a chronic condition characterized by high blood pressure, often due to increased constriction of blood vessels.
