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.
A battery, which is actually an electric cell, is a device that produces electricity from a chemical reaction. Strictly speaking, a battery consists of two or more cells connected in series or parallel, but the term is generally used for a single cell. A cell consists of a negative electrode; an electrolyte, which conducts ions; a separator, also an ion conductor; and a positive electrode.
