Heart

• The superior vena cava (SVC) brings deoxygenated blood from the upper part of the body to the right atrium.
• The pulmonary trunk is located between the left and right ventricles.
• The coronary arteries supply blood to the heart muscle itself.
• The pulmonary veins carry oxygenated blood from the lungs back into the heart.
• The pulmonary trunk carries oxygen-poor blood away from the heart to the lungs, where it picks up oxygen and releases carbon dioxide.
• The bicuspid valve separates the left atrium from the left ventricle.
• The aortic semilunar valve separates the left ventricle from the aorta.
• The superior vena cava brings deoxygenated blood from the upper body to the right atrium.
• The inferior vena cava brings deoxygenated blood from the lower body to the right atrium.
• The pulmonary semilunar valve separates the right ventricle from the pulmonary trunk.
• The coronary veins drain blood from the myocardium back into the right atrium.
• The coronary arteries supply blood to the myocardium (heart muscle).
• Blood flows through the pulmonary semilunar valve between the right ventricle and the pulmonary trunk.
• Blood flows through the mitral (bicuspid) valve between the left atrium and the left ventricle.
