As you guys know, a heart pump our blood to all of our body. So my question is, how did a heart got an energy to pump our blood to all of our body? How a heart can move? Please let me know

I’m only a high school student so I don’t know a lot about heart and it’s movement. But I think the reason the heart pumps the blood through the body is through contractions of the muscle of the heart. Just like the contraction of, let’s say, a biceps if you’re trying to pull something towards yourself. The main difference between these two muscles is that you can proactively control the contraction of the biceps and the heart does it on its own. And then you also asked about how the heart gets the energy for its movement. I’m not really sure but I think the heart gets the energy for its movement just like any other moving segment in the human body. Food. You break down the food by the so called enzymes. The whole progress of breaking down the food into energy (not really but I would suggest you read something about glycolysis, citrate cycle and the respiratory chain if you really want to get a grasp of what’s happening) is called digestion. The heart moves due to the heart muscle. The movement is made possible by food intake which then converts to energy. Sorry if it’s hard to understand because English is my second language. If you have any questions I will answer them but I like I said I’m not really sure about these informations.

There are cardiac cells that work like natural pace makers and produce electrical pulses that make the cardiac muscle cells contract.

So, the cardiac sells is an energy for a movement heart?

According to me, all organs get energy form the food. I mean ATP. So it gets energy from it. And it is able to move/pump due to cardiac fluid around the heart which ends up giving flexibility to it. What do you think?

Cuz' it has strength. Moreover, its chambers make the blood circulate through them by their regular contractions and expansions. So it moves.

But when a heart out of our body, it still can be move right? What do you think?

our heart have a unspecific cells lika a pace makers-sinoatrial is the first pace maker,it creat impulse and because of this impulse we have a heart beat! after this impulse goes to all atrium and atrium start pressing and blood pump to ventriculus-we have also atrioventriculus pace maker(second pace maker) after atriums-impulse goes to it and it cause ventriculus pressing and blood pump into the body from heart

Thank for telling me

So where a heart get an energy to move? An energy, my question is. Where the energy come from?

we mustnot forget heart actives automotically-why ?it is because of Na Ca..these electrolites moving and of these movings pace maker’s membranes started acting and started depolarization and from this started everything .. this is how hurt works! in our hurt’s cells are a big amount of mitochondrya it cause glicholys which provide energy, also we have Krepsys cycle and reactions like this give heart’s cell energy
