Cohutta Wilderness. The Cohutta Wilderness was designated in 1975, expanded in 1986, and currently consists of 36,977 acres (149.64 km2). Approximately 35,268 acres (142.72 km2) are located in Georgia in the Chattahoochee National Forest and approximately 1,709 acres (6.92 km2) are located in Tennessee in the Cherokee National Forest.
Best Answer: The earthworm has a closed circulatory system. An earthworm circulates blood exclusively through vessels. There are three main vessels that supply the blood to organs within the earthworm. These vessels are the aortic arches, dorsal blood vessels, and ventral blood vessels. The aortic arches function like a human heart. There are five pairs of aortic arches, which have the responsibility of pumping blood into the dorsal and ventral blood vessels. The dorsal blood vessels are responsible for carrying blood to the front of the earthwormâs body.
However, even closed circulatory systems differ as we move further up the evolutionary tree. One of the simplest types of closed circulatory systems is found in annelids such as the earthworm. Earthworms have two main blood vesselsâa dorsal and a ventral vesselâwhich carry blood towards the head or the tail, respectively. Blood is moved along the dorsal vessel by waves of contraction in the wall of the vessel. These contractible waves are called 'peristalsis.'
