They have an open circulatory system.<\/strong><\/p>\n<p>Annelids are a group of segmented worms that have a closed circulatory system. This means that their blood is contained within blood vessels, which transport it throughout the body. The blood is pumped by a heart, which is located in the anterior part of the body. The blood carries oxygen and nutrients to the tissues, and removes waste products.<\/p>\n<p>Annelids also have a nerve net, which is a network of nerves that controls their movement and other bodily functions. The nerve net is not as complex as the nervous system of vertebrates, but it is still able to coordinate the activities of the different parts of the <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> body.<\/p>\n<p>Annelids perform gas exchange across their skin.
