Venous return controls EDV (end diastolic volume) and thus stroke volume and cardiac output.
Venous return is dependent on:
- blood volume and venous pressure
- vasoconstriction caused by the sympathetic nervous system
- skeletal muscle pumps
- pressure drop during inhalation
What else can I help you with?
What factor affecting stroke volume is determine by venous return?
contractility
What are the two factors of cardiac output?
The stroke volume and the heart rate. The stroke volume is the volume of your blood and heart rate is how many beats there are per minute.
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 are some factors affecting the volume of a drop?
temperature is the only one i can think of
One of the factors affecting density is?
Density = Mass/Volume. As a result, density is entirely dependent on both mass and volume.
What 3 factors determine stroke volume?
End-diastolic volume (EDV), total peripheral resistance (TPR), and contractility.
Why do you have a increased stroke volume?
An increase in stroke volume can be due to factors such as increased cardiac contractility (force of heart contractions), decreased afterload (pressure the heart must overcome to eject blood), or increased preload (volume of blood returned to the heart). These factors can result in more blood being pumped out by the heart with each contraction, leading to an increased stroke volume.
What causes stroke volume to decrease?
Stroke volume can decrease due to factors such as dehydration, heart failure, or certain heart conditions that weaken the heart muscle. Other factors include excessive bleeding, severe infections, or certain medications that affect heart function.
Cardiovascular system what sv stands for?
stroke volume - the volume of blood pumped by your heart in one beat
The amount of blood pushed out of the ventricle with each contraction is called?
Stroke-Volume
Factors affecting cost behavior?
Volume Price Efficience Sales mix Production changes
What factors are most important factors when dealing with density?
Mass and volume.
