Prime purpose of this lecture is to present on Anatomy of Heart. The heart is a hollow muscle. It is located on the left side of your chest, about the size of your clenched fist. It is divided into four sections called chambers. Two chambers are on the left and right side. Each side has an upper and lower chamber. The heart is a muscular organ in humans and other animals, which pumps blood through the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, and also assists in the removal of metabolic wastes.
