Expert Solution

Step 1

Heart:

In most animals, the heart is a muscular organ. Blood is pumped by this organ through the circulatory system's blood arteries. The blood that is pumped around the body supplies nutrients and oxygen to the body while transporting metabolic waste, including carbon dioxide, to the lungs. The human heart is situated in the centre of the chest, between the lungs, and is roughly the size of a closed fist.

Three layers of tissue make up the heart:

epicardium, myocardium, endocardium

The pericardium, a thin outer covering that guards your heart, surrounds these layers.
