A network of blood vessels is a system of interconnected tubes that transport blood throughout the body. The term 'RETE' is derived from the Latin word for 'NET, ' and is used to describe this type of network. The network of blood vessels is composed of arteries, veins, and capillaries, which carry oxygen-rich and oxygen-poor blood to and from the heart. This network is essential for the body to function properly, as it helps to regulate blood pressure, deliver nutrients, and remove waste products.
