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.
Â­ Blood now returns to the heart from the lungs by way of the pulmonary veins (8) and goes into the left atrium (LA) (9). When the LA contracts, blood travels through the mitral valve (10) and into the left ventricle (LV) (11).ll blood enters the right side of the heart through two veins: The superior vena cava (SVC) and the inferior vena cava (IVC) (see figure 3). The SVC collects blood from the upper half of the body.
