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 blood is the transport system by which oxygen and nutrients reach the body's cells, and waste materials are carried away. The heart, a muscular organ, positioned behind the ribcage and between the lungs, is the pump that keeps this transport system moving.n the capillaries, food and oxygen are released to the body cells, and carbon dioxide and other waste products are returned to the bloodstream. The blood then travels in veins back to the right side of the heart, where it is pumped directly to the lungs.
