Describe the arterial blood flow to and away from the Circle of Willis

Homework Answers

Answer #1
  • The circle of Willis provides alternate pathways for blood to reach brain tissue in the case of impaired blood flow in this system
  • The circle of Willis is comprises of a communiqué of arteries at the bottom of the brain comprising of the internal carotid arteries, anterior cerebral arteries, posterior communicating arteries, posterior cerebral arteries, and basilar arteries.
  • The circle of Willis also permit blood to flow crosswise the midline of the brain.
  • The circle of Willis thus aids as a security valve role for the brain, permitting collateral to take place if the flow is abridged to one area.

9. Which is/are TRUE about the arterial baroreceptors: A) Decreased stretch of the arterial baroreceptors triggers the “baroreceptor reflex” to dilate veins, decreasing stroke volume B) The “baroreceptor reflex” has very little direct effect on blood pressure in the brain since there is very little autonomic input to the arterioles in the brain C) Increased stretch of the arterial baroreceptors leads to increased activity of the sympathetic nerves to the heart D) The arterial baroreceptors are not active when mean...
