1.Outline the flow of blood through the heart starting with largest veins. Include all chambers, valves, and major arteries. Use the format A> B-→ to

Which of the following is correct regarding the flow of blood in reference to the left side of the heart? a. Blood flows from the left atrium, through the bicuspid valve, into the left ventricle, through the aortic semilunar valve, and then into the aortic arch b. Blood flows from the left atrium, through the aortic semilunar valve, into the left ventricle, through the bicuspid valve, and then into the aortic arch c. Blood flows from the left atrium, through the bicuspid valve, into the left ventricle, into the aortic arch, through the aortic semilunar valve, and then into systemic arterial system

Fill in the Blank: Match the number to the part of the heart in the flow of circulation. Superior Vena Cava/[1] --> Right Atrium --> [2] --> Pulmonary Artery --> Lungs --> [3]--> [4] --> Left Ventricle--> [5] --> Body 1 2 3 4 5 ៦ 8 [Choose ] [Choose ] [Choose ] [Choose ] [Choose ] A W P & B

12. THE HUMAN HEART: Match the labels to the parts of the heart below. WRITE THE LETTER ONLY. Key Blood flow b) h) g) a) f) aorta right atrium right ventricle inferior vena cava d) e) _pulmonary artery left atrium right ventricle superior vena cava

The diagrams show structures that comprise the external and internal regions of the heart. Label the components A to L

1. Match the heart structure with the description. Mediastinum A. The thinner, more delicate membrane that forms a double layer around the heart. Арех. B. Middle layer of the heart responsible for the pumping action of the heart and is composed of cardiac muscle tissue C. Valve located between the right atrium and right ventricle - closes to prevent blood from going back into right atrium Fibrous pericardium Serous pericardium D. Anatomical region that extends from the stemum to the vertebral column, from the first rib to the diaphragm, and between the lungs. Location of the heart. Epicardium E. Chamber that receives deoxygenated blood from the right atrium and pumps it out to the pulmonary trunk through the pulmonary semilunar valve. F. Smooth, innermost layer of the heart wall in direct contact with the blood being pumped. Myocardium Endocardium G. Wrinkled pouch like structure on the anterior surface of each atrium - increase the capacity of the atria Auricle H. The pointed tip of…

below is a diagrammatic representation of the heart. Y Identify structure X. Explain the function of structure Y. Explain how the structure of the heart allows for the efficient pumping of blood around the body to deliver oxygen to, and collect carbon dioxide from, the body tissues. Describe three ways in which the structure of each of capillaries, veins and arteries are adapted to carry out their functions.

Match the area where blood will flow within the heart during systole (1 point) If blood is in the right atria during diastole, during systole it will move to: If blood is in the right ventricle during diastole, during systole it will move to: If blood is in the left atria during diastole, during systole it will move to: If blood is in the left ventricle during diastole, during systole it will move to: Choose... Choose... The Systemic circulation (body) The Right Ventricle The Pulmonary Circuit The Left Ventricle Choose... ÷ +

List the correct pathway through which blood must flow in relation to regions of the heart. Include major blood vessels (arteries and veins) attached directly to a heart chamber, the four heart chambers, and the four heart valves. (Assume blood is currently in the vena cava and will soon enter the aorta.)
