The right side of the heart supplies the lungs via the pulmonary artery and the left side supplies the rest of the organs via the aorta. Situated in the right atrium are the sinoatrial (SA node) cells, these cells are source of the electrical signal controlling the heartbeat.<\/p><p>The heartbeat starts when the electrical signal from the SA node causes the two upper chamber muscles of the heart to contract. The blood in the atria is then forced through the atrio-ventricular AV valves in to the two lower chambers. The atrio-ventricular valves (mitral valve, tricuspid valve) close to only allow fluid to pass in one direction, this prevents blood returning to the atria as the ventricles contract. The ventricles contract when the electrical signal that started in the SA node passes through the AV node to the ventricle chamber muscles. The blood is then forced through the aortic and pulmonic valves into the arteries. The aortic and pulmonic valves close again only allowing fluid to pass in one direction, they are situated one on the left side of the heart and the other on the right side. The when these valves close, the heart muscles relax allowing the chambers to expand and the atria to refill with blood from the veins ready for the start of the next beat.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-12a0c218 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"12a0c218\" data-element_type=\"section\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t\t\t<div class=\"elementor-background-overlay\"><\/div>\n\t\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-55110ce3 elementor-invisible\" data-id=\"55110ce3\" data-element_type=\"column\" data-settings=\"{&quot;animation&quot;:&quot;bounceInDown&quot;}\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-31c554ff elementor-widget elementor-widget-heading\" data-id=\"31c554ff\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">A Helping Hand For A Hoping Heart.<\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-33939dd3 elementor-widget elementor-widget-text-editor\" data-id=\"33939dd3\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.
