Where does blood flow through the heart? Your heart has four chambers, which you can think of like rooms in your home. Two are on the right side of your heart (right atrium and right ventricle), and two are on the left side (left atrium and left ventricle).
The heart is a hollow, muscular organ that pumps oxygenated blood throughout the body and deoxygenated blood to the lungs. This key circulatory system structure is comprised of four chambers.
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.
Heart (right lateral view) The heart is a muscular organ that pumps blood around the body by circulating it through the circulatory/vascular system. It is found in the middle mediastinum, wrapped in a two-layered serous sac called the pericardium.
When blood leaves the heart to go to the rest of the body, it travels through a large artery called the aorta. A balloon-like bulge, called an aortic aneurysm , can sometimes occur in the aorta. Learn about how your heart circulates blood to your lungs and throughout your body.
This image shows the four chambers of the heart and the direction that blood flows through the heart. Oxygen-poor blood, shown in blue-purple, flows into the heart and is pumped out to the lungs. Then oxygen-rich blood, shown in red, is pumped out to the rest of the body, with the help of the heart valves.
This video provides a simple step-by-step diagram of the cardiac blood flow and a chart of the circulation pathway. Includes the anatomy of the heart and an animation quiz at the end in order to test your knowledge!
Passage of blood through the left atrium, bicuspid valve, left ventricle, aorta, tissues of the body, and back to the right atrium constitutes the systemic circulation. Blood pressure is greatest in the left ventricle and in the aorta and its arterial branches.
The heart is the epicenter of the circulatory system, which supplies the body with oxygen and other important nutrients needed to sustain life.
Understanding its basic anatomy is crucial to understanding how it functions. This article provides a comprehensive look at the heart's structure with a detailed, labeled diagram and realistic photos, guiding you through each part and its role in the circulatory system.
