M _____ Left ventricle _____ Right ventricle _____ Left atrium _____ Right atrium _____ Aorta _____ Pulmonary vein _____ Pulmonary artery _____ Superior vena cava _____ Inferior vena cava _____ Tricuspid valve _____ Bicuspid valve _____ Pulmonary semilunar valve _____ Aortic semilunar valve ANATOMY OF THE HEART 1. The _____________________ (atria or ventricle) receives blood from the body or lungs, while the _____________________________ (atria or ventricles) pump out blood to the body and lungs. 2. List the 2 chambers and 2 vessels that carry oxygen-rich blood. 3. List the 2 chambers and 2 vessels that carry oxygen-poor blood. 4. What is the function of your heart valves? 5. Where is the SA Node located? 6. The SA Node is also known as the heart’s ________________________________. 7. What causes the heart sounds (lup/dup sound)? CIRCULATION OF BLOOD 8. Write oxygenated or deoxygenated next to the following structures: a. Right atria & ventricle ____________________________________ b. Vena cava ____________________________________ c. Aorta ____________________________________ d. Pulmonary vein ____________________________________ e. Left atria & ventricle ____________________________________ f. Pulmonary artery ____________________________________ 9. Describe where the blood flows from the valves by writing body cells, lungs or heart next to the structure. a. Blood from the aorta goes to the ________________________ b. Blood from the pulmonary vein goes to the ________________________ c. Blood from the pulmonary artery goes to the ________________________ d. The vena cava receives blood from the ________________________ 10. Write the correct sequence (1-8) when tracing the path blood travels from the body cells to the lungs. a. _______ right ventricle e. _______ pulmonary valve b. _______ tricuspid valve f. _______ right atria c. _______ lungs g. _______ pulmonary artery d. __1____ body cells h. _______ vena cava BLOOD VESSELS 11. Write arteries, capillaries, or veins next to the correct description. a. ______________________ carries blood towards the heart b. ______________________ smallest and most abundant blood vessel c. ______________________ carries blood away from the heart d. ______________________ where gas exchange occurs e. ______________________ has the greatest blood pressure f. ______________________ where veins and arteries connect BLOOD 12. List the function of blood. 13. Write the function of the following blood cells: BLOOD CELLS FUNCTION Erythrocytes (RBC) LEUKOCYTES (WBC) Platelets 14.
