Nov 8, 2023 · 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.
Apr 14, 2024 · Blood flow moves in one direction through the chambers of the heart. Electrical impulses are generated to make your heart beat. Heart valves open and shut to regulate blood flow. Cardiac arrhythmia, heart blocks, heart valve disease, heart failure, and cardiac ischemia can all affect the normal flow of blood to and from the heart.
Mar 24, 2022 · Heart valves control the flow of blood so that it moves in the right direction. The valves prevent blood from flowing backward. The heart has four valves. The tricuspid valve separates the right atrium and right ventricle. The mitral valve separates the left atrium and left ventricle.
Apr 13, 2024 · Here is the step-by-step flow of blood, including the chambers and valves: Deoxygenated blood from the body flows to the heart via the superior vena cava and inferior vena cava. Right atrium. Tricuspid valve. Right ventricle. Pulmonary arteries.
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
Blood moves through the bicuspid (or mitral) AV valve into the left ventricle. From here the blood is pushed through the systemic semilunar valve (aortic valve) into the aorta and then out into the body. Oxygen-depleted blood returns to the right atrium by way of the superior vena cava and the inferior vena cava. Attributions.

3D Model. The heart, a hollow muscular organ, is located in the center of the chest. The heart has two sides, right and left. The right and left sides of the heart each have an. Atrium: Upper chamber that collects blood and pumps it to the lower chamber. Ventricle: Lower chamber, which pumps blood out of the heart.
Sep 21, 2021 · Blood circulates through your heart and through these circuits in a continuous pattern: The pulmonary circuit: This circuit carries blood without oxygen from the heart to the lungs. The pulmonary veins return oxygenated blood to the heart.
The lungs are composed of a few hundred million tiny air sacs called alveoli, each of which are surrounded by a network of blood vessels (capillary bed) which carry deoxygenated blood, shown in blue, and carry out oxygenated blood, shown in red. (Adapted from Wikipedia image)
