Myocardium · Srdeční sval (myokard)
Muscles
Looks like
The heart's own muscle, thickest in the left ventricle, fed by the coronary arteries.
What it does
Squeezes the blood out with every beat, without ever resting.
Keeping it well
Blood pressure, cholesterol and sugar treated, movement, no smoking; muscle lost in a heart attack does not grow back.
