Heart Labeling
This flashcard set covers major heart structures and their functions related to blood circulation. It includes important vessels, chambers, and valves, helping to understand how blood flows through the heart and lungs for oxygenation.
superior vena cava
a large vein carrying deoxygenated blood into the heart
Key Terms
superior vena cava
a large vein carrying deoxygenated blood into the heart
aorta
the main artery of the body, supplying oxygenated blood to the circulatory system
right pulmonary veins
responsible for carrying oxygenated blood from the lungs back to the left atrium of the heart
right atrium
receiving chambers
tricuspid valve
prevent back flow of blood into the right atrium
right ventricle
responsible for pumping oxygen-poor blood to the lungs

| Term | Definition |
|---|---|
superior vena cava | a large vein carrying deoxygenated blood into the heart |
aorta | the main artery of the body, supplying oxygenated blood to the circulatory system |
right pulmonary veins | responsible for carrying oxygenated blood from the lungs back to the left atrium of the heart |
right atrium | receiving chambers |
tricuspid valve | prevent back flow of blood into the right atrium |
right ventricle | responsible for pumping oxygen-poor blood to the lungs |
inferior vena cava | a large vein carrying deoxygenated blood into the heart |
pulmonary artery | the artery carrying blood from the right ventricle of the heart to the lungs for oxygenation |
left pulmonary veins | large blood vessels that receive oxygenated blood from the lungs and drain into the left atrium of the heart |
left atrium | ts primary roles are to act as a holding chamber for blood returning from the lungs and to act as a pump to transport blood to other areas of the heart. |
bicuspid valve | regulates blood flow from the upper left chamber (left atrium) into the lower left chamber (left ventricle), the heart's main pumping chamber |
aortic valve | revent the regurgitation of blood from the aorta into the left ventricle during ventricular diastole and to allow the appropriate flow of blood—the cardiac output —from the left ventricle into the aorta during ventricular systole |
pulmonary valve | the valve is opened by the increased blood pressure of the ventricular systole (contraction of the muscular tissue), pushing blood out of the heart and into the artery. It closes when the pressure drops inside the heart. |
left ventricle | during diastole, the ventricles relax and fill with blood again. 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. |
