WebEach side of the heart consists of an atrium and a ventricle which are two connected chambers. The atria (plural of atrium) are where the blood collects when it enters the heart. Bayliss effect or Bayliss myogenic response is a special manifestation of the myogenic tone in the vasculature. The Bayliss effect in vascular smooth muscles cells is a response to stretch. This is especially relevant in arterioles of the body. When blood pressure is increased in the blood vessels and the blood vessels distend, they react with a constriction; this is the Bayliss effect. Stretch of the …
