Simplified answer: Oxygenated blood reaches the brain via the Internal Cerebral Artery and the Vertebral Arteries. These vessels have many branches (Posterior, Middle, and Anterior Cerebral Arteries) going to different parts of the brain. Once oxygen reaches the capillary beds of these vessels it diffuses through the capillary walls to supply brain tissue.

Why does the blood leaving most organs in the brain have less oxygen than when it entered the brain?
The blood leaving most organs in the brain has less oxygen because the brain consumes a significant amount of oxygen and nutrients.

This results in a decrease in oxygen content in the blood leaving the brain.
