A heart itself is a muscle of our body. Hearts anatomy includes the ducts, veins, arteries and other canals.It do have muscles,base on its physical appearance. It has a voluntary and involuntary muscles for its movement.
They're the muscles in people's bodies that pump blood throughout the circulatory system.
No. Many of our muscles are controlled involuntarily by the brain. We would probably die if we had to think about breathing with our lung muscles or pumping blood with our hearts.
Myocardial fibrosis is the abnormal thickening of the heart valves. This thickening is caused by the muscles in the hearts cells becoming impaired.
because it has to work 24 7. if you think about it, you could work out for a month and you can start to develope muscles so of course if it works forever, your hearts gonna get strong

Hearts are trump is correct.
The heart muscles are specialized muscles. The fibers are a structural syncitium, meaning they behave as one. There are gap junctions between them allowing them to propagateaction potentials with ease. These muscles also have automaticity, a property that enable them to generate impulses on their own. In addition, they conduct action potentials very well.Leg muscles and other skeletal muscles lack automaticity and the electrical properties are different. Hence, it is not possible to construct a 'beating' heart with them. However, they (leg muscles) may be instructed to go back in time: to form 'stem cells'. These stem cells may then be groomed to grow into cardiac myocytes, by the proper expression of respective genes.
In a standard deck of 52 cards, there are 13 hearts. Half of these hearts are even-numbered, which means there are 6 even-numbered hearts in the deck. The even-numbered hearts in a deck of cards are the 2 of hearts, 4 of hearts, 6 of hearts, 8 of hearts, 10 of hearts, and Queen of hearts.
They have 5 hearts. =)
As with all mammal hearts, when needed (exertion, danger) the heart will beat faster, pumping more oxygen enriched blood round the body and muscles.
