Why is the relationship between pressure and volume of a confined gas inverse?
As the volume decreases, the pressure increases, and as the volume increases, the pressure decreases, which constitutes an inverse relationship
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.
Where does volume happen at?
Density decreases
If mass increases and volume stays the same then density decreases?
Density is mass / volume. Therefore, when mass decreases, density will also decrease.Density is mass / volume. Therefore, when mass decreases, density will also decrease.Density is mass / volume. Therefore, when mass decreases, density will also decrease.Density is mass / volume. Therefore, when mass decreases, density will also decrease.
What happens to temperature as volume decreases?
The volumes decreases. See Boyle's Law
Does stroke volume increase if end diastolic volume decrease?
false, stroke volume decreases if the end volume decreases.
Describe the relationship between stroke volume and pump rate?
As stroke volume increases, pump rate decreases. This is an inverse relationship.
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.
What does cardiac output do if the heart rate decreases?
Cardiac output = heart rate X stroke volume Thus, if the heart rate decreases so will the cardiac output, assuming the stroke volume is constant.
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.
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 happens to volume if the radius and height decreases?
The volume decreases!
The amount of blood pushed out of the ventricle with each contraction is called?
Stroke-Volume
Fluid that fills the pericardial sac acts to decrease what during heart activity?
Fluid filling the heart decreases the stroke volume by impeding dilation of the ventricles.
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?
How does tachycardia affect stroke volume and cardiac output?
Lowers stroke volume
Sound intensity decreases when what decreases?
Sound intensity decreases when amplification (volume) decreases.
