PVD is often found in people with problems with the arteries that supply blood to the heart (coronary artery disease). That is because atherosclerosis, which causes coronary artery disease, affects arteries throughout the body.Atherosclerosis is the buildup of plaque on the walls of the arteries.VD is often found in people with problems with the arteries that supply blood to the heart (coronary artery disease).

What are the Functions of a Battery. A lead acid storage battery is an electrochemical device that produces voltage and delivers electrical current. The battery is the primary âsourceâ of electrical energy used in vehicles today. Itâs important to remember that a battery does not store electricity, but rather it stores a series of chemicals, and through a chemical process electricity is produced. Basically, two different types of lead in an acid mixture react to produce an electrical pressure called voltage. This electrochemical reaction changes chemical energy to electrical energy and is the basis for all automotive batteries.
There are a variety of chemical and mechanical devices that are called batteries, although they operate on different physical principles. A battery for the purposes of this explanation will be a device that can store energy in a chemical form and convert that stored chemical energy into electrical energy when needed. These are the most common batteries, the ones with the familiar cylindrical shape.
