The heart can be made from stem cells

Scientists are studying red-spotted newts to help develop therapies for people with heart damage. This reptile, when needed, can transform its cells (as if it were stem cells) to build new cardiac muscles. In another study, scientists created a beating heart from embryonic stem cells in the lab.

Horse's heartbeat is similar to those who nourish them

Heart failure causes a heart attack

Breaking up with a lover or losing a family member can cause heart attack risks. These lesions can also stimulate the release of stress hormones into the blood, temporarily "unconscious" the heart.

This 2.8-liter heavy muscle bundle is the symbol of love for many countries
