LIFESCI 2 Chapter Notes - Chapter 44: Inferior Vena Cava, Superior Vena Cava, Pulmonary Artery
Document Summary
The cardiovascular system: a closed system that consists of the heart, blood vessels, and the blood. Blood vessels provide the path for the blood to travel. Blood carries nutrients and picks up wastes: pulmonary circuit. Delivers deoxygenated blood from the heart to the lungs: systematic circuit. Delivers oxygenated blood from the heart to the body. Valves of the heart: tricuspid valve. Connects right atrium to right ventricle: bicuspid valve. Connects left atrium to left ventricle: pulmonary semilunar valve. Connects right ventricle to the pulmonary trunk: aortic semilunar valve. Connects left ventricle to aorta: pressure from blood and contraction of heart causes valves to open and close. Blood vessels of the heart: superior vena cava. Brings blood from anything above the diaphragm to the right atrium: inferior vena cava. Brings blood from anything below the diaphragm to the right atrium: pulmonary trunk. Splits in left pulmonary artery and right pulmonary artery that goes to respective lungs.
