Stroke volume is the volume of blood pumped by the right/left ventricle of the heart in one contraction. its the volume ejected per beat from each ventricle, equal end-diastolic volume minus end systolic volume: SV=EDV-ESV

Stroke Volume is the amount of blood ejected by the venticle of the upper heart but the lower heart contains blood this is with every heart beat Stroke Volume is the amount of blood ejected by the venticle of the upper heart but the lower heart contains blood this is with every heart beat

according to the book The laboratory mouse (Elsevier Publishers) is it somewhere between 24 - 40 microliters (depending on a measuring method and experimental conditions)

What is the difference between stroke volume and swept volume in air compressor?

Stroke volume refers to the volume of air that is displaced or compressed by the piston in a single stroke. Swept volume, on the other hand, refers to the total volume that is displaced by the piston over the entire displacement cycle, including the clearance volume. In summary, stroke volume is the volume displaced in one stroke, while swept volume is the total volume displaced throughout the entire cycle.

How can stroke volume can be altered?

Stroke volume is determined by three factors, altering any of them can change the stroke volume. These factors are preload, afterload, and contractility. The relationship is: SV = P*C/A What this means is that preload and contractility are directly proportional to the stroke volume and afterload is inversely proportional to stroke volume. If you increase preload (within certain limits), stroke volume will increase according to the Starling curve. Increasing contractility (many things can increase this), makes the heart pump harder and increases stroke volume. Increasing afterload decreases stroke volume. All of these can be reversed (decreasing preload and contractility = decreased stroke volume, etc). Get a good physiology book and it will explain all of this very well.
