Explanation:

1. Arteries carry oxygen - rich blood and nutrients like glucose to brain cells. Carbon - monoxide is a toxic gas and not a substance provided by arteries to brain cells. Carbon - dioxide is a waste product, not a substance provided to brain cells by arteries. Oxygen is essential for cellular respiration in brain cells. Nitrogen is a major component of the air we breathe but is not a key substance directly provided to brain cells by arteries for their normal function. Glucose is the main energy - source for brain cells.
2. In medical terms, CVA stands for cerebrovascular accident, which is another term for stroke.

Answer:
