Resin cast of human heart blood vessels. This model was achieved by injecting liquid plastic into a real heart. The plastic resin fills the blood vessels and, once the resin sets, the tissue is dissolved away leaving a perfect replica of the blood supply.

Resin cast of arteries in the brain. Your brain consumes about 20% of your body's energy so it needs a lot of blood flow to keep it supplied with nutrients. Even knowing that, the density of the neurons here amazes me--they look almost the size of the brain itself!

Coronary calcium is a marker for plaque (fatty deposits) in a blood vessel or atherosclerosis (hardening of the arteries).  The presence and amount of calcium detected in a coronary artery by the CT scan, indicates the presence and amount of atherosclerotic plaque.  These calcium deposits appear years before the development of heart disease symptoms such as chest pain and shortness of breath.
