Heart Beats on


I don't know where my obsession with drawing hearts came from. The heart is just a weird thing. Its electric, it pumps blood to every part of your body. How weird.

I have always been interested in anatomy. But hearts specifically have always interested me.


The heart is a muscular organ about the size of a fist, located just behind and slightly left of the breastbone. The heart pumps blood through the network of arteries and veins called the cardiovascular system.


The human heart has four chambers: two upper chambers (the atria) and two lower ones (the ventricles), according to the National Institutes of Health. The right atrium and right ventricle together make up the "right heart," and the left atrium and left ventricle make up the "left heart." A wall of muscle called the septum separates the two sides of the heart. A double-walled sac called the pericardium encases the heart, which serves to protect the heart and anchor it inside the chest. Between the outer layer, the parietal pericardium, and the inner layer, the serous pericardium, runs pericardial fluid, which lubricates the heart during contractions and movements of the lungs and diaphragm.

The heart's outer wall consists of three layers. The outermost wall layer, or epicardium, is the inner wall of the pericardium. The middle layer, or myocardium, contains the muscle that contracts. The inner layer, or endocardium, is the lining that contacts the blood. The tricuspid valve and the mitral valve make up the atrioventricular (AV) valves, which connect the atria and the ventricles. The pulmonary semi-lunar valve separates the right ventricle from the pulmonary artery, and the aortic valve separates the left ventricle from the aorta. The heartstrings, or chordae tendinae, anchor the valves to heart muscles.





I wanted to dive deeper into what makes up a heart because I am trying to understand where my inspiration for creating hearts came from. I don't actually know. Here is a sketch in a random sketchbook of mine. I want to start keeping a daily sketchbook but i never get there. I need to do a better job with time management because my instinct is to say yes to everything and then i am too tired to be my best self. I am trying to learn to say no. I am an empath and I often think of others before myself and it's frustrating. I am trying to be better about self care, but it is so hard to put myself first.



Why is the heart associated with emotions? Well The History channel has a great explanation of this HERE. It has roots in a medieval artists reading the philosopher Aristotle, who described the human heart as having three chambers with a small dent in the middle.
