Ask a hand to hold the sadness of heartbreak and hand bleeding (heart is glass)

No heart, because the heart is too bloody. And the scientific basis that the heart can't be held in the hand:

An organ that promotes blood circulation in humans and vertebrates. The human heart is in the middle of the chest, slightly to the lower left, conical, and about the size of my fist. There are four chambers in it, the upper two are atria and the lower two are ventricles. The relaxation and contraction of atria and ventricles promote blood circulation throughout the body.

Expand the scientific knowledge of the heart;

The heart is located in the chest, between the lungs above the diaphragm, and about two-thirds is on the left side of the midline. The heart is like an inverted, slightly flat cone, like a peach.

The blunt top circle faces to the lower left and is adjacent to the anterior chest wall, and its body surface is projected at 0.5- 1.0cm inside the clavicle midline of the fifth intercostal space of the anterior chest wall, so the top pulse can be seen or touched here. My heart base is very wide, and there are big blood vessels coming in and out of it, facing the upper right back, adjacent to the esophagus and other organs of the posterior mediastinum.
