The video shows a person's hand holding a black marker and drawing on a piece of paper. The drawing is of a heart with arteries and veins. The person is seen drawing a line from the heart to the top of the paper, then drawing lines from the heart to the bottom of the paper, and finally drawing lines from the heart to the left and right sides of the paper. The person's hand is steady as they draw, and the marker leaves a bold, black line on the paper.
