A labeled, close-up picture of Sanguis Dei. Here, the ornamentation of the face of the monstrance is such that it alludes to an anatomical heart: it is divided into the four chambers of a human heart, and the golden rays of light emanating from the monstrance double as the veins and arteries of the heart. Traditionally, in medical illustrations, the right atrium and right ventricle are colored blue, while the left atrium and left ventricle are red. This is so as the right side of the heart pumps deoxygenated blood and the left side of the heart transports oxygenated blood. Likewise, the four “chambers” of the monstrance are colored accordingly and appear to be flowing with liquid. Several of the golden rays are also colored according to the positioning of the veins and arteries of a human heart: the three openings of the aorta at the top (red), the pulmonary artery on the left (blue), the four pulmonary veins, with two on each side (red), and the superior vena cava and inferior vena cava on the right (blue).
