These animals have a simple cardiovascular system with a single circuit of fluid that bathes the organs. The fluid is pumped out of the heart and through the body by contractions of the body wall muscles. It is then sucked back into the heart by special contractions of the heart muscles.<\/p>\n<p><strong>Closed circulatory systems<\/strong> are found in vertebrates, such as fish, amphibians, reptiles, birds, and mammals. These animals have a more complex cardiovascular system with a double circuit of fluid. The first circuit, called the systemic circuit, carries blood from the heart to the body tissues. The second circuit, called the pulmonary circuit, carries blood from the body tissues to the heart.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_the_System_works\"><\/span>How the System works<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The system works by using a central server to manage a database of contact information. When a user wants to send a message to another user, the system looks up the recipient&#8217;s contact information in the database and sends the message to them.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_Cardiovascular_System\"><\/span>The Cardiovascular System<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The cardiovascular system is responsible for circulating blood throughout the body. It includes the heart, blood vessels, and blood. The heart is a muscle that pumps blood through the arteries and veins. The arteries carry oxygenated blood away from the heart, and the veins carry deoxygenated blood back to the heart.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Types_of_Circulatory_System\"><\/span>Types of Circulatory System<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>There are three types of circulatory system: open, closed, and semi-closed.<\/p>\n<ul>\n<li>The open circulatory system is found in invertebrates and has a heart that pumps blood out to the body and then back to the heart. There is no distinction between the blood inside and outside of the blood vessels.<\/li>\n<li>The closed circulatory system is found in vertebrates and has a heart that pumps blood to the body and then back to the heart. The blood vessels are separated from the body&#8217;s tissues by a membrane.<\/li>\n<li>The semi-closed circulatory system is found in some vertebrates and has a heart that pumps blood to the body and then back to the heart. The blood vessels are separated from the body&#8217;s tissues by a membrane, but there is a direct connection between the veins and the heart.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Heart_of_the_Circulation_System\"><\/span>Heart of the Circulation System<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The circulatory system is a network of blood vessels that transports blood throughout the body. The heart is the central organ of the circulatory system, and it pumps blood through the vessels. The blood carries oxygen and nutrients to the tissues, and it removes waste products from the tissues.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"The_Lymphatic_System\"><\/span>The Lymphatic System<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The lymphatic system is a network of organs and vessels that helps rid the body of waste and fights infection. The lymphatic system includes the lymph nodes, thymus, spleen, and tonsils. Lymphatic vessels branch out like tree branches throughout the body, collecting fluid called lymph from the tissues.<\/p>\n<p>The lymphatic vessels carry the lymph to the lymph nodes, where the lymph is filtered. The lymph nodes produce white blood cells that help fight infection. The lymphatic system also includes the bone marrow, which produces white blood cells.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Structure_of_the_Circulatory_System\"><\/span>Structure of the Circulatory System<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li>The circulatory system is a series of organs and vessels that circulate blood, nutrients, hormones, and oxygen throughout the body. The system is made up of the heart, blood vessels, and blood.<\/li>\n<li>The heart is a muscular organ that pumps blood through the circulatory system. The heart is located in the chest cavity, just left of the breastbone. The heart is divided into four chambers: the left and right atria and the left and right ventricles.<\/li>\n<li>The atria are the upper chambers of the heart. The ventricles are the lower chambers of the heart. The left ventricle is the larger of the two ventricles and is responsible for pumping blood to the body. The right ventricle is responsible for pumping blood to the lungs.<\/li>\n<li>Blood vessels are the tubes that carry blood throughout the body. The largest blood vessels are the aorta and the vena cava. The aorta carries blood from the left ventricle of the heart to the rest of the body. The vena cava carries blood from the body back to the right atrium of the heart.<\/li>\n<li>Blood is a fluid that contains red blood cells, white blood cells, and platelets. Red blood cells are responsible for carrying oxygen throughout the body. White blood cells are responsible for fighting infection. Platelets are responsible for clotting blood.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Circulatory_System_Function\"><\/span>Circulatory System Function<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The circulatory system is responsible for the distribution of nutrients and oxygen to the body&#8217;s cells, and the removal of carbon dioxide and other waste products. It also helps to regulate body temperature.<\/p>\n<p>The circulatory system consists of the heart, arteries, veins, and capillaries. The heart is a muscular organ that pumps blood through the arteries and veins. The arteries carry blood away from the heart, and the veins carry blood back to the heart. The capillaries are the smallest blood vessels, and they connect the arteries and veins.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is Blood Circulatory System The circulatory system is a network of organs and vessels that circulate blood throughout the [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_yoast_wpseo_focuskw":"Blood Circulatory System","_yoast_wpseo_title":"%%title%% %%page%% %%sep%%","_yoast_wpseo_metadesc":"The circulatory system is a network of organs and vessels that circulate blood throughout the body.
