Document Summary

Physiology notes: blood flow regulation and heart rate (day 3) Over wider ranges, the blood flow remains relatively constant. Legit the definition of pressure-flow auto regulation. Left or right coronary arteries (these are the first branch of the. Differences between left and right right: no dip in beginning left: a dip to 0 in the beginning, the peak flow is higher than the right. During systolic = generating force = low low low for left. During diastolic = rest = less force = more for left. During contraction, vessels in heart are compressed, so the lumen is less able to push blood. When blood flow is low but the demand for o2 is high, accumulation of.
