because the blood flow to the myocardial tissue was intercepted by a fleet of magical unicorns of pure destruction and i would very much reccomend seeing a doctor as soon as possible, i am very concerned about your issue with your myocardial tissue as in some cases it can lead to death or many years of paralysis, my second and only other suggestion is that you follow the yellow brick road and make new friends on the way to give you moral support and help you through your final days of your tragic , unicornish death and i am very very sad to announce that you may also have a condition called 'youareafairyitis'
What else can I help you with?
Which valves in the heart are open during diastole?
During systole, both atrioventricular valves (tricuspid and mitral) are closed. The aortic valve is open. During diastole, both atrioventricular valves are open, and the aortic valve is closed.
Is diastole the highest pressure in the arteries?
No, diastole is the period when a particular chamber of the heart relaxes. the highest pressure period is during systole.
What is meant by systole and diastole?
The ventricles of heart have two states: systole(contraction) and diastole (relaxation). During diastole blood fills the ventricles and during systole the blood is pushed out of the heart into the arteries. The auricles contract anti-phase to the ventricles and chiefly serve to optimally fill the ventricles with blood.http://www.answers.com/systole
Which phase of the heartbeat does the heart fill with blood?
during diastolic phase the chambers of heart get filled with blood systolic phase and diastolic phase are the phases oh heartbeat and diastolic phase is also known as resting phase.
What term is used for arterial pressure during ventricular diastole?
diastolic blood pressure
What is the name for Blood pressure recorded during ventricular diastole?
diastole
What coronary arteries fill with blood to deliver to heart during what phase?
diastole
When the heart contracts it is called diastole and what increases?
During a diastole, the blood pressure momentarily increases.
What is the relaxing phase of the cardiac cycle?
The relaxing phase of the cardiac cycle is called diastole. During diastole, the heart chambers (atria and ventricles) relax, allowing them to fill with blood. This is followed by the contracting phase called systole.
What AV and semilunar valve positions during ventricular diastole?
The AV valve is open and the semilunar valve is closed during ventricular diastole.
The relaxation phase of the heartbeat is called?
The relaxation phase of the heartbeat is called diastole. During diastole, the heart ventricles relax and fill with blood in preparation for the next contraction.
What percentage of coronary blood flow occurs during diastole?
Myocardial blood supply is from the right and left coronary arteries, which run over the surface of the heart giving branches to the endocardium (the inner layer of the myocardium). Venous drainage is mostly via the coronary sinus into the right atrium, but a small proportion of blood flows directly into the ventricles through the Thebesian veins, delivering unoxygenated blood to the systemic circulation. Oxygen extraction by the tissues is dependent on consumption and delivery. Myocardial oxygen consumption is higher than in skeletal muscle (65% of arterial oxygen is extracted as compared to 25%). Therefore any increased myocardial metabolic demand must be matched by increased coronary blood flow. This is a local response, mediated by changes in coronary arterial tone, with only a small input from the autonomic nervous system.
What happens during mid to late diastole?
It decreases.
Which valves in the heart are open during diastole?
During systole, both atrioventricular valves (tricuspid and mitral) are closed. The aortic valve is open. During diastole, both atrioventricular valves are open, and the aortic valve is closed.
Does the heart do the most work during systolic?
Yes. It "rests" during diastole.
Do coronary arteries get their blood supply during systole or diastole?
Coronary arteries primarily receive blood supply during diastole when the heart is relaxed and filling with blood. This is because during systole, when the heart is contracting to push blood out, the coronary arteries can get compressed which reduces blood flow to the heart muscle.
Is diastole the highest pressure in the arteries?
No, diastole is the period when a particular chamber of the heart relaxes. the highest pressure period is during systole.
