Which of the following intrinsic or extrinsic changes would result in an increase in stroke volume? Group of answer choices An increase in diastolic blood pressure A decrease in preload A decrease in ventricular compliance An increase in venous return Arterial constriction

An increase in diastolic blood pressure

Explanation:

Stroke volume is defined as the volume of blood let out from the left ventricle in a single heartbeat.

Diastolic pressure is the pressure on the arterial wall between heartbeats.

As Stroke volume increases, end diastolic volume increase slightly. This increased disatolic volume leads to the Frank-Starling mechanism which contributes to the increased stroke volume (stroke volume increases when end-diastolic volume increases). Since pressure and volume are directly proportional, an increase in stroke pressure also leads to an increase in the diastolic pressure.

answer: a. the kind of population living in your neighbourhood.

the census explorer data tool by the us census bureau allows the user to zoom in on any neighbourhood within the united states and find the kind of people residing in that by race and age.  

the tool needs to needs to be used twice – once in order to find what type of people reside in a neighbourhood, and then to see the age groups of the people in the same neighbourhood.
