as the body's systems get older, they require more blood flow to operate, thus causing increased heart rate
There is no evidence that the heart has developed and changed as organisms have become more complex over time. Scientists do believe that the human heart is a product of evolution and has spent millions of years perfecting itself in order to keep humans alive.
A heart cell is eukaryotic because it contains a defined nucleus and membrane-bound organelles. Eukaryotic cells, such as those found in humans and other multicellular organisms, are more complex than prokaryotic cells, which lack these features. Heart cells, specifically cardiomyocytes, are specialized for contraction and function within the complex structure of heart tissue.
