This organ system makes the human body.

This is a connective tissue found in the heart. Heart is divided into Three layers epicardium, mayocardium (muscular layer) and endocardium.

Answer 2

A myocardiocyte is a heart muscle cell, but it makes up the myocardium

We know it's more than a cell but less than an organ, because a heart muscle is found in the heart (an organ).
Therefore, it's a type of tissue.
