How the frank starling law of the heart helps to explain the influence of venous return on stroke volume?
The Frank-Starling law of the heart states that the force of cardiac contraction is proportional to the initial length of the cardiac muscle fibers, which is influenced by the volume of blood filling the heart (preload). As venous return increases, the heart fills with more blood, stretching the myocardial fibers and enhancing their contraction strength. This results in an increased stroke volume, illustrating how greater venous return directly boosts the amount of blood ejected with each heartbeat. Thus, the law highlights the intrinsic relationship between venous return and stroke volume regulation.

Principles of Frank-Starling law of the heart?
The Frank-Starling law of the heart (also known as Starling's law or the Frank-Starling mechanism) states that the greater the volume of blood entering the heart during diastole (end-diastolic volume), the greater the volume of blood ejected during systolic contraction (stroke volume) and vice-versa.This allows the cardiac output to be synchronized with the venous return, arterial blood supply and humeral length[1] without depending upon external regulation to make alterations.
Why does the shaping tool move faster during the return stroke?
During the return stroke it does not remove any material, it is an idle stroke so to improve the cutting efficiency it will move faster during the return stroke. Pradip Kotak.
State and explain quick return mechanism?
Quick return mechanismA reciprocating motion, for operating the tool of a shaping machine etc, in which the return is made more rapidly than the cutting stroke, so as to reduce the idling time.

What is example of Whitworth quick return mechanism?
Whitworth quick return mechanism is a device where reciprocation motion in forward stroke is slower then the return stroke.

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.
