Verified step by step guidance

1. Understand the term 'hydrocephalus': The prefix 'hydro-' means water, and '-cephalus' refers to the head. Therefore, hydrocephalus involves an accumulation of fluid in the head.
2. Identify the fluid involved: In the context of hydrocephalus, the 'water' refers to cerebrospinal fluid (CSF), which is a clear fluid that surrounds the brain and spinal cord.
3. Determine the location of excess fluid: Hydrocephalus is characterized by an abnormal buildup of cerebrospinal fluid within the ventricles (cavities) of the brain.
4. Consider the effects of fluid accumulation: The excess CSF can increase pressure inside the skull, potentially leading to an enlarged head, brain damage, or other neurological issues if not treated.
5. Conclude the expected location of excess fluid: Given the definition and effects, Connie should expect the excess 'water' or cerebrospinal fluid to be in the head, specifically within the brain's ventricles.
