∙ 12y agoThe first heart sound, called S1, occurs when the tricuspid and mitral valves close as the ventricles fill with blood.

Cardiac cycle when do you hear the first heart sound snd second?
when the ventricles closes and between the atria and the ventricles.
What is occurring during the diastolic period?
Diastole is the phase in the cardiac cycle that allows filling of blood into the ventricle. It corresponds to the lower number in the blood pressure measurement. A normal upper limit of the blood pressure falls in the range less than 120/80 mm Hg. Above this value, it is considered pre-hypertension based on The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.During the diastolic period the ventricle is in the fifth phase of the cardiac cycle. This phase is termed isovolumetric relaxation which occurs immediately after the second heart sound. In this phase, all valves of the heart are closed. The volume of blood in the ventricle during this phase of the cardiac cycle remains constant. Following the fifth phase of the cardiac cycle is the rapid filling of blood into the ventricle. This cycle corresponds to the opening of the mitral and tricuspid valves located between the left and right atria and ventricle, respectively. The next phase of the cardiac cycle, called diastasis, is the longest phase of the cardiac cycle. In this cycle, the ventricle continues to fill with blood but at a much slower rate. The final phase of diastole corresponds to the first phase of the cardiac cycle. In this phase of the cardiac cycle, the atria contracts to provide additional filling of blood into the ventricle. After the final phase of diastole, the systolic phase of the cardiac cycle begins.
What is the vowel sound in cycle?
The Y in cycle is a long I vowel sound, as the E is silent.
When lightning occurs you first see the light and then hear the sound why?
Really? Cause light travels faster than sound.
Does the first heart sound occurs at the same time as the P wave of the electrocardiogram?
yes
How long is a cycle in a sound wave?
A cycle in a sound wave is the time taken for one complete vibration.
How do you spell Accores?
well sound i out "occurs" but you spell it occurs
What happens to blood pressure and flow when cardiac tamponade is brought on by trauma?
When tamponade occurs because of trauma, the sound of the heart beats can become faint, and the blood pressure in the arteries decreases, while the blood pressure in the veins increases.
What occurs when things vibrate?
Sound
Is serene a schwa?
'Serene' itself is not a schwa, as a schwa is an unstressed vowel sound. In 'serene', the schwa occurs in the first e.
What occurs when a sound moves away from you?
the sound´s frequency decreases
What does cycle mean in reference to sound?
In acoustic physics, "cycle" refers to the time between repetitions of the peak amplitude of the sound wave.
