The property by which the body remains at rest or remains in motion with constant velocity is called inertia, and Newton's First Law is often called the law of inertia. Experience tells us that some object have more inertia than others. It is obviously more difficult to change the motion of a boulder than that of a basketball, for example. The inertia of an object is measured by its mass -- quantity of matter it contains. The quantity of matter in an object is determined by the number of atoms and molecules of various types in it. Thus, unlike weight, mass does not vary with location. The mass of an object is the same on earth, in orbit, or on the surface of the moon. In practice, it is very difficult to count and identify all of the atoms and molecules in an object, and-so operationally masses are determined by comparison with the standard kilogram.
The human liver is a dark red-brown organ with a soft, spongy texture. It occupies the upper right and part of the upper left quadrants of the abdominal cavity. The mass of the human liver is about 1.5 kg.
The liver is a simple structure. It consists of two main lobes, left and right. As the liver does its work, nutrients are collected, wastes are removed, and chemical substances are released into the body through these vessels.
The liver's most important functions include helping the body to digest fats and to store reserves of nutrients. It also filters poisons and wastes from the blood and regulates the levels of many chemicals found in the bloodstream. The liver is only one of its kind among the body's vital organs in that it can redevelop or grow back the cells that have been destroyed by some short-term injury or disease. If the liver is damaged repeatedly over a long period of time, it may undergo changes that permanently interfere with its function.
