  In this article, the dynamics and complexity of a noise induced blood flow
system have been investigated. Changes in the dynamics have been recognized by
measuring the periodicity over significant parameters. Chaotic as well as
non-chaotic regimes have also been classified. Further, dynamical complexity
has been studied by phase space based weighted entropy. Numerical results show
a strong correlation between the dynamics and complexity of the noise induced
system. The correlation has been confirmed by a cross-correlation analysis.
