Do Human Hearts Mirror that of a Sharks’ Heart?

The Huge Shark Has Only 2 Heart Chambers

Isn’t it interesting to know that a shark’s heart functions like a human heart with some major variations? While the human heart has four chambers, two upper chambers called atria and two lower chambers called ventricles, the shark’s heart has two chambers only. Sharks must keep swimming continuously to ensure that there is blood circulation throughout the body. If this movement was required in the case of humans too, there would be decreased rates of obesity/overweight existing worldwide. Human blood circulation is an involuntary action and the heart pumps blood to all other body parts by uniformly organized contractions of the four chambers. What would happen if the contractions do not happen in an organized fashion? It results in heart failure!

Heart failure happens when one or more chambers of the heart are unable to contract normally. Heart is not healthy enough to pump with enough pressure to push enough blood into circulation. All major risk factors, age and high blood pressure being the two most important ones, for heart failure must be detected at an early stage and kept under control. Any heart defects or failures when detected at an early stage, has more success rate and the chances of leading a heart-healthy life is also on the higher side.
