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.
Using these stretching and contracting muscles, they push themselves forward. The fluid in each segment cannot be compressed, and contraction of the muscles causes the segments, and thus the body, to change shape. Swelling enables the body to open up gaps in the soil, while a limp body can move through tight spaces.The number of segments in mature earthworms ranges from about 50 to over 500.any body organs are repeated in adjacent segments â for example nephridia, which function like kidneys, occur on most segments. Often there are paired hearts in two to five adjacent segments, and paired testes in two adjacent segments.
