What is the volume and pressure inside the left ventricle at the end of diastole related to?
The related value is called "stroke volume" and is equal to the end-diastolic volume minus the end-systolic volume, i.e. the maximum volume (pre-beat) less the minimum volume (post-beat). The typical volumes for the left ventricle are slightly smaller than those of the right ventricle, but the stroke volume may be slightly greater.
What is the pulmonary SL valve?
The pulmonary semilunar valve is located in the right ventricle at the opening to the pulmonary artery, which carries deoxygenated blood from the heart to the lungs where it will pick up oxygen. During systole, which is the active part of the heartbeat, the valve is forced open by increased pressure inside the ventricle and blood flows from the heart into the artery. During diastole the pressure inside the heart returns to its lower state, and the pressure inside the artery causes the valve to close again, thus preventing the blood from flowing back into the heart.
Why the volume of the air molecules inside of the syringe changes?
This is the effect of the pressure.
What is the volume of air in the tank of capacity 1500cc if you pump only 500cc?
Assuming the tank was not in a vacuum, the VOLUME stays constant. The volume is the total area inside the tank. The pressure would change when 'pumped up'. The volume would not. The pressure inside would also change based on the temperature, relative to the outside pressure.
If the air inside a balloon is heated the volume will?
The volume would increase as the pressure of the expanding air increases.
What is the volume of a gas increases its pressure decreases mean?
It means that if the gas is allowed to expand into a larger volume, the pressure - inside the container that contains the gas - will be less.
What will happen to the pressure inside the container if the volume of a container of gas is reduced?
The pressure inside the container will increase. Pressure (P) is force(F) divided by the area(A) it hits on. If you decrease the area, you increase the pressure.
If a balloon is squeezed what a happens to the pressure of the gas inside the balloon?
If a balloon is squeezed, then that means the volume is decreasing. Volume and pressure vary indirectly, which means that when one goes up, the other goes down. So when you are decreasing the volume of the balloon, the pressure inside is going up (assuming constant mass and temperature).
Why does a syringe plunger go back in if you pull it out?
When the plunger is pulled, the volume inside increases. This reduces the pressure inside, and the air pressure outside forces liquid in, in an effort to make the pressure inside and outside the syringe equal again.
What will happen to gas pressure when the volume is decreased?
When the temperature of a gas is increased at a constant pressure, its volume increases. When the temperature of a gas is devreased at constnt pressure, its volume decreases.
What happens to the pressure and volume inside the thoracic cavity when you pull the rubber diaphragm down the lung model?
When the diaphragm is pulled down, the volume of the thoracic cavity increases, and the air pressure in the thoracic cavity decreases. This causes inhalation.
If a balloon is squeezed what happens to the pressure of the gas inside the balloon?
If a balloon is squeezed, then that means the volume is decreasing. Volume and pressure vary indirectly, which means that when one goes up, the other goes down. So when you are decreasing the volume of the balloon, the pressure inside is going up (assuming constant mass and temperature).
