Graphite is a mineral composed exclusively of the element carbon. Graphite has the same chemical composition as Diamond, which is also pure carbon, but the molecular structure of Graphite and Diamond is entirely different.This causes almost opposite characteristics in their physical properties. Graphite is rather common mineral, but fine crystals are rare.Most Graphite mining areas produce enormous quantities from a single or several large Graphite vein s, but collector specimens in good crystals are not commonly encountered.raphite has the same chemical composition as Diamond, which is also pure carbon, but the molecular structure of Graphite and Diamond is entirely different.
A , Cardiology (Cardiovascular Disease), answered. Blood is pumped into the lungs by the right lower chamber of the heart, called the right ventricle. It then returns to the left upper chamber, called the left atrium, and flows into the left ventricle, which pumps it to the rest of the body.
Blood enters the heart from the superior vena cava and the inferior vena cava. It is rich in carbon dioxide. It goes from the right atrium to the right ventricle. It's then pu â¦ mped through the pulmonary arteries to the lungs.lood full of oxygen returns to the heart through the pulmonary vein. Then from the left atrium to the left ventricle. The blood, now rich in oxygen, flows through the aorta. The aorta branches into smaller arteries. The arteries carry blood all over the body.
