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.
In systemic circulation, the oxygenated blood is pumped into the muscles and the organs of the body through the arteries by the left ventricle. The nutrients and gases are exchanged at the capillaries. Then the blood enters the veins filled with cellular waste and carbon dioxide. This deoxygenated blood is then taken to the right atrium by the veins. The veins are blood vessels which carry the deoxygenated blood back to heart from the body tissues in our circulatory system.
