<span>The electrical stimulus in the heart begins in the APEX OF THE ATRIA at the SINOATRIAL NODE. The heart has its own electrical conduction system that enables it to work as a unit and supply oxygenated blood throughout the body. This system needs to work in a sequential manner so that the delivery of unoxygenated blood to the lungs will not backflow to other parts of the heart and the body. </span>
Answer:
Desiccation
Explanation:
Skin healing involves a huge range of events and special situations. It consists of a perfect and coordinated cascade of cellular and molecular events that interact for repaving and tissue reconstitution. With all the other metabolic processes in the body, healing depends largely on the degree of hydration the individual's body is. In cases of dehydration, desiccation may occur, which is localized dehydration of a wound, which consists of slow healing and scabbing of the wound tissues.
