Yes it is,,,while one part of the heart is in systole (ie ventricles) the other part is in diastole (ie atrium) the blood is continually moving thru the body via the arteries and veins via the cardiac output. There is always a little blood left in the ventricles after Systole though.....
YES.
Diastole. The origin of the coronary arteries are blocked by the semi-lunar leaflets of the aortic valve during systole.
Neither, theoretically the two ventricles contract simultaneously. The coronary arteries begin as two holes just above the leaflets of the aortic valve. During systole the leaflets block the coronary arteries and prevent blood flow to them. It is during diastole (of both ventricles) that blood returns to the coronary vasculature.
Diastole is the lowest blood pressure measured in the peripheral arterial supply.
Diastole
myoglobin
The nose produces a continuous supply of mucous to put moisture in the air and catch dust and bacteria.
Transmural perfusion pressure represents the amount of pressure in the coronary arteries that supply the layers of the heart muscle (the TRANSMURAL part). The formula is: Aortic diastolic pressure - LVEDP (L Ventricle End Diastolic Pressure). Keep in mind the coronaries ONLY receive blood during diastole because of the twisting forces applied on the heart during systole.
During cardiac systole the left ventricle contracts, the semi lunar valves open and occlude the coronary arteries. During diastole the valves close and because of the elasticity of the aorta which has just been stretched blood now flows into the coronary arteries. The reason for this is that it is easier to supply blood to the cardiac muscle when it is relaxed.
yep
