The heart contracts and relaxes during a cardiac cycle.
systolic to diastolic
This is called systole. When the heart chambers relax, it is called distole. I hope that this helps you out!
The transmission delay at the AV node in the heart allows both ventricles to relax and be refilled by the contracting atria. After the AV node delay, the ventricles contract and force blood into the aorta (systemic circulation).
The cardiac muscle fiber absolute refractory is a long period of time (longer then skeletal muscles), so you cannot tetanize cardiac muscle fibers because it has to relax before it is able to contract again.
When alcohol is consumed, the heart function is increased and the ability of the heart to contract and move blood is increased
Yes. Electrical signals to the cardiac muscle causes the heart to relax and contract.
Heart
Because its funny looking like a bunch of bananas
they are in the heart of humans only
auto-rhythmic cardiac muscle
systolic to diastolic
muscles contract and relax by bring about movements.
Yes the heart does contract and relax for every moment of ones life .This action enables the blood to circulate the body efficiently
They contract and relax
Your heart receives blood and pumps the same in your body. So the heart chambers has to contract and relax. So the blood is pumped at interval and in quantum. This produces the heart beats.
An echocardiogram shows how well your heart is pumping. As a muscle, all parts of the heart must contract and relax in a sequence. With certain heart problems, part of the heart might contract ineffectively or not at all. The echocardiogram gives important diagnostic information.
This is called systole. When the heart chambers relax, it is called distole. I hope that this helps you out!
