Analyzing blood vessel diameters of the Willis circle in male and female respondents, whose presentation we give in Table 2, we can conclude that in both age groups among males, slightly higher diameters of the internal carotid artery (0.1-0.2 mm) was recorded compared to the female population and higher values of the P1 segment of the posterior cerebral artery, while the rear communicating artery in females was 0.1 mm larger in diameter than in males within younger group of respondents.
