It helps to protect the heart and keep it in the correct position. The pericardium also helps to lubricate the heart and reduce friction as it beats.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Structure_of_the_Heart_Wall\"><\/span>Structure of the Heart Wall<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The heart wall is a muscle that separates the heart&#8217;s chambers. It is made up of three layers:<\/p>\n<ul>\n<li>The outer layer is made up of cardiac muscle cells.<\/li>\n<li>The middle layer is made up of connective tissue.<\/li>\n<li>The inner layer is made up of cardiac muscle cells.<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Function_of_Heart\"><\/span>Function of Heart<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The heart is a muscle that pumps blood throughout the body. The heart is divided into four chambers: the left atrium, the left ventricle, the right atrium, and the right ventricle. The heart has two valves: the mitral valve and the tricuspid valve. The heart is powered by the cardiac muscle. The cardiac muscle is composed of cardiac cells, which are specialised muscle cells. The cardiac cells contract and relax to power the heart.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Human_Respiratory_System\"><\/span>Human Respiratory System<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The human respiratory system is a series of organs responsible for the intake and exchange of oxygen and carbon dioxide between an organism and its environment. The system includes the nose, mouth, throat, larynx, trachea, bronchi, and lungs.<\/p>\n<p>The respiratory system is a group of organs that work together to bring oxygen into the body and remove carbon dioxide. The main organs of the respiratory system are the nose, mouth, pharynx, larynx, trachea, bronchi, and lungs.<\/p>\n<p>The nose is the organ of smell and also helps to warm and moisten incoming air. The mouth is where food is chewed and swallowed and also helps to warm and moisten incoming air. The pharynx is the passage that connects the mouth and nose to the larynx. The larynx is the voice box and also helps to keep food and drink from entering the lungs. The trachea is a tube that carries air from the larynx to the bronchi. The bronchi are two tubes that carry air from the trachea to the lungs. The lungs are two organs that are filled with air. The air enters and leaves the lungs through the bronchi.<\/p>\n<p>The respiratory system works by bringing air into the body and removing carbon dioxide. When you breathe in, the air enters the nose or mouth and travels down the pharynx to the larynx. The larynx opens and the air travels down the trachea to the bronchi. The bronchi lead to the lungs, where the air enters the alveoli. The alveoli are small sacs that are filled with air. The air in the alveoli is then brought into the bloodstream, where the oxygen is transferred to the red blood cells. The red blood cells then take the oxygen to the rest of the body. When you breathe out, the air leaves the lungs and travels back up the bronchi to the trachea. The trachea opens and the air travels up to the larynx. The larynx opens and the air travels up the pharynx to the mouth. The mouth opens and the air is expelled from the body.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Mediastinum in Anatomy The mediastinum is a section of the chest cavity that separates the lungs from the heart and [&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":"Mediastinum","_yoast_wpseo_title":"","_yoast_wpseo_metadesc":"The mediastinum is a section of the chest cavity that separates the lungs from the heart and other thoracic organs at Infinitylearn.com.","custom_permalink":"biology\/mediastinum\/"},"categories":[11],"tags":[],"table_tags":[],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v17.9 -
