A heartbeat is made up of the rhythmic contraction and relaxation of the heart muscle, primarily the atria and ventricles, driven by electrical impulses generated by the sinoatrial (SA) node. This electrical activity causes the heart to pump blood throughout the body, delivering oxygen and nutrients while removing waste products. The heartbeat can be measured in beats per minute (BPM) and is influenced by various factors, including physical activity, emotional state, and overall health.
The lower the temperature the faster the heart beat which made us shiver.
You will not be able to feel a heart beat, but a heart beat can be detected. Usually at around 5 weeks a heart beat can be heard.
The myocardium is the thickest layer of the heart made of contractile muscles that pumps blood.
yes there are ppl with no heart beat and their dead
i think it does have a slow heart beat!
no your heart beat is the same
An insect's heart is a tube-like structure that runs along the insect's back and pulsates to pump hemolymph (insect blood) through its body. Contractions of muscles surrounding the heart cause it to beat and circulate nutrient-rich hemolymph to the insect's tissues.
There is no such tissue, the heart can beat automatically, without an external stimulus, it has several groups of automatic cells that discharge electricity currents that make the muscle cells in the heart beat sinchronically. Also, this automatic beat can be slowed down or can be made quicker by influences of autonomous nervous system, but remember, it can work by itself. It is called an involuntary muscle.
It's not good at all.
Valves have nothing to do with heart beat The pacemaker of the heart controls the heart beat
The contractive phase of the heart beat is systole.
Heart Beat Records was created in 1981.
