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.
The heart pumps blood along two pathways in your body, the pulmonary circuit and the systemic circuit. In the pulmonary circuit, the heart pumps blood to the lungs, then back to the heart. From this pathway, blood picks up oxygen and drops off carbon dioxide in the lungs. Put simply, blood is oxygenated in the lungs.
