Gently stroke or pet it This will wake it without starling it.
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.
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.
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.
The Frank-Starling law of the heart describes the relationship between?
stroke volume, end-diastolic volume, and contraction strength
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.
What happens to the quick return ratio when the stroke length is reduced?
What happens to the quick return ratio when the stroke length is reduced?
Working principal type description operation of shaping machine?
there are two stroke include in this forward stroke &return stroke during the forward stroke machine works means it removes the material from workpiece & during the return stroke machine remains idle
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.
