What happens to density if an objects volume remains constant but its volume is decreased?
If an object's volume remains constant but its volume is decreased,its density becomes ambiguous and mutually inconclusive.
What is the average stroke volume in an adult at rest?
The average stroke volume of the heart at rest for an adult is 70 ml.
What does SV stand for in the relationship CO equals HRSV?
In the relationship CO equals HRSV, SV stands for stroke volume.
What happend to the volume of urine as the solute concentration in the interstitial space was increased?
the urine volume decreased
What happened to the urine volume as the concentration gradient increased?
The urine volume decreased as the concentration gradient increased.
How would a decrease in blood volume affect both stroke volume and cardiac output?
It's decreased ... unless the rate falls, which is the normal cardiac response.
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.
What is a heartbeat affected by?
The individual heartbeat, or contraction, can be modified by input from the sympathetic and parasympathetic nervous systems. This modification can include increased or decreased contraction ratios, increased or decreased stroke volume and increased or decreased rate of contraction.
What is a common effect of hypertension on stroke volume?
There are a number of long term effects on stroke volume. These may include reduction in blood pressure and capillarisation among others.
Is heartbeat affected by heartbeat?
The individual heartbeat, or contraction, can be modified by input from the sympathetic and parasympathetic nervous systems. This modification can include increased or decreased contraction ratios, increased or decreased stroke volume and increased or decreased rate of contraction.
What is the normal compensatory response to a decreased cardiac contractility often seen in myocardial infarction?
Increase in heart rate as Cardiac Output = Heart rate x Stroke volume. As SV will be decreased, HR increases to compensate.
The amount of blood pushed out of the ventricle with each contraction is called?
Stroke-Volume
What is the formula to get stroke volume?
stroke volume =end diastolic volume - end of systalic volume. But how to measure these volume i don't know?
Does stroke volume increase if end diastolic volume decrease?
false, stroke volume decreases if the end volume decreases.
How does tachycardia affect stroke volume and cardiac output?
Lowers stroke volume
What is decreased blood flow associated with a stroke?
ischemia
Does the mitral valve prolapse increase decrease the stroke volume?
Mitral valve prolapse may decrease the stroke volume, if it is associated with significant backflow. It decreases the effeciency of the left ventricular contraction.
