Atrial and Ventricular Diastole

Graphite pencil on bristol board.

A re-drawing of a University project I set myself on Medical Illustration. I loved the original project two years ago, but thought I could do much better, so decided to redo the pictures as my skills had improved.

The first of a series of three images showing the stages of a heart beat. This image shows Atrial and Ventricular Diastole, where the heart is relaxed and blood can enter.

(I drew straight from a pig's heart I had cut in half and photographed for the project, and therefore may not be entirely scientifically correct in muscle placement)

If anyone thinks this needs a 'mature' tag, then please just say.
