The circulatory system, also known as the cardiovascular or vascular system, is a network of organs that facilitates the circulation of blood throughout the body. It’s responsible for transporting essential substances such as nutrients, oxygen, carbon dioxide, hormones, and blood cells to all organs and tissues. It encompasses three components: the heart, blood, and blood vessels which work together to ensure the continuous flow of blood throughout the body, maintaining proper oxygenation and nutrient delivery to all tissues.
