left part of heart
Left ventricle is an important part of heart which contains oxygenated blood and pumps it with high pressure through aorta. It provides body with fresh blood.
The heart is in the thoracic cavity in a part called the mediastinum. It is protected by the pericardium, a membranous sac that surround the heart. The mediastinum is that space in the thoracic cavity between the lungs that contains the heart. It also contains the aorta, esophagus, trachea and thymus.The pleural cavity is the space in the chest between the lungs.
you have two lower chambers in the heart, left ventricle that releases rich blood that contains oxygen to the body through the aorta and the right ventricle that releases poor blood to the lungs through the pulmonary artery.
The ARTERIES carries the blood away from the heart.
The systemic circulation is the part of the circulatory system that carries oxygenated blood away from the heart to the body and returns deoxygenated blood back to the heart. In contrast, the pulmonary circulation is the part of the circulatory system that carries deoxygenated blood from the heart to the lungs for oxygenation and returns oxygenated blood back to the heart.
