网页2015年3月24日 · The left ventricle is the thickest of the heart’s chambers and is responsible for pumping oxygenated blood to tissues all over the body. By contrast, the right...
Physiology, Left Ventricular Function - StatPearls - NCBI Bookshelf
网页2022年9月19日 · The primary function of the left ventricle is to provide sufficient cardiac output to maintain blood flow to other organ systems. Cardiac output results from systolic contraction of the left ventricle, which can be influenced by preload, afterload, and contractility. Cardiac output (CO) is the amount of blood …
Left ventricular hypertrophy - Symptoms and causes - Mayo Clinic
网页2024年8月6日 · Left ventricular hypertrophy is a thickening of the wall of the heart's main pumping chamber, called the left ventricle. This thickening may increase pressure within the heart. The condition can make it harder for the heart to pump blood.
Left Ventricle Heart - Physiopedia
网页The left ventricle is an integral part of the cardiovascular system. Left ventricular contraction forces oxygenated blood through the aortic valve to be distributed to the entire body. With such an important role, decreased function caused by injury or maladaptive change can induce symptoms of the disease.
Ventricle (heart) - Wikipedia
网页The left ventricle receives oxygenated blood from the left atrium via the mitral valve and pumps it through the aorta via the aortic valve, into the systemic circulation. The left ventricular muscle must relax and contract quickly and be able to increase or lower its pumping capacity under the control of the nervous system.
Heart ventricles: Anatomy, function and clinical aspects - Kenhub
网页2023年8月3日 · The base of the left ventricle begins at the left atrioventricular valve (a.k.a. the mitral valve, bicuspid valve) and continues toward the apex of the heart. The ventricular lumen then curves around toward the aortic valve , where blood is ejected into the aorta and systemic circulation.
Left Ventricle | Complete Anatomy - Elsevier
网页The left ventricle is conical in shape. It’s the dominant chamber of the heart and has the thickest walls (up to 12 mm). A small portion of the left ventricle helps to form the anterior, sternocostal surface which includes the apex. However, the majority of the left ventricle forms the inferior, diaphragmatic surface of the heart.
Left-Sided Heart Failure: Symptoms, Causes and Treatment - Cleveland Clinic
网页2021年12月2日 · What is left-sided heart failure? This condition occurs when the left side of the heart no longer functions appropriately. There are two types: Systolic heart failure: The bottom pumping chamber of your heart called the left ventricle is too weak to pump blood out to your body. It’s also known as heart failure with reduced ejection fraction.
Left ventricle - Structure (Diagram), Location, Function
网页2024年3月2日 · The left ventricle is located in the bottom left portion of the heart, beneath the left atrium and to the left of the right ventricle. It sits posteriorly to the sternum (breastbone) and anteriorly to the vertebral column.
How Blood Flows Through the Heart & Body - Cleveland Clinic
网页2023年11月8日 · The mitral valve connects your left atrium and left ventricle. The aortic valve connects your left ventricle and aorta (large artery that carries blood away from your heart to the rest of your body). Blood flows through the heart in a series of arteries, ventricles, veins and valves.
