Is the heart always pumping blood when pressure in the left ventricle is rising?

No when pressure in the left ventricle first rises, the heart is contracting but no blood is leaving the heart. During this initial phase of contraction, bother the AV valves and the semilunar valves are closed. The increase in the pressure is the result of increased tension as the cardiac muscle contracts. When the pressure in the ventricle exceeds the pressure in the aorta, the aortic semilunar valves are forced open, and blood is rapidly ejected from the ventricle.

Which woody plant grows from a single woody trunk rising into the air?
Aeroxyl
WHere does wind start?
Wind can be caused by either pressure or temperature differences. From there you get into which is cause and which is effect. Wind starts when you have heated air rising and cooler air flowing in to take its place. As the lighter heated air rises, the cooler, heavier air will rush in to take its place. Once the heated air cools in the upper atmosphere, it then falls back.
What kind of currents are caused by saltier heavier water sinking and less salty water rising?
Deep. nova netThe currents caused by something like saltier water sinking and less salty water rising are called density currents.

What happens to air pressure when the barometer is rising?
The air pressure is rising.
Is high pressure rising pressure?
No. High pressure is pressure that is higher than an established normal pressure. The pressure may be rising, falling, or remain the same
Is high pressure characterized by sinking air or rising air?
it is rising think of clear skies with a high pressure rising the air up.
Does the Intertropical Convergence Zone have high pressure with rising air?
Low pressure is associated with rising air. The ITCZ is an area of low pressure.
What will the weather be like when air pressure is rising?
When air pressure is rising, it means that a high pressure area is coming in your direction. High pressure areas tend to bring very sunny and calm weather so the weather should improve when the air pressure is rising
What weather do you think is coming when air pressure is rising?
If air pressure is rising (called a "rising barometer") it indicates fair weather coming.
What does a rising atmoshereic pressure indicate?
Changes in the barometric pressure indicate a change in the weather. A rising barometric pressure usually indicates clear, stable weather.
Why is precipitation heavier in the persistent low pressure zones of the world?
Where low pressure is persistent, air is always converging and rising. When air rises, it often cools to its dewpoint to condense into clouds and precipitation.
What is the difference between the air pressure rising and falling?
the fisrt one is about air pressure rising and the other one is dealing with falling
Does warm air and high pressure causes rising air?
Yes warm air and low pressure can cause rising air.
Is a high pressure system characterized by rising air or sinking air?
Rising air
