Cerritos College A&P 150 Fall 2020Lecture Exam 3 Study Guide – October 26DIRECTIONS: Use the PowerPoints and the textbook (use this last if necessary) to answer these study guide questions. CARDIOVASCULAR SYSTEM PART 1What are the 3 parts of the cardiovascular system?How is the heart like two side-by-side pumps? Where does blood go when it is pumped out of the right side of the heart? What is this circuit called?Where does blood go when it is pumped out of the left side of the heart? What is this circuit called?What are the 6 functions of the cardiovascular system? Be able to describe them.What 3 body cavities does the heart reside in? (The 3rd one is mentioned in the instructor narration!)Where is the heart located in the body? What borders the heart laterally (and a little bit anteriorly)?What borders the heart posteriorly?What borders the heart anteriorly?What borders the heart inferiorly?What group of structures are located superiorly to the heart? What is the purpose of the pericardium?Be able to list and describe the pericardium and its components.Which specific layer of pericardium is also part of the heart wall? What is called as part of the heart wall?Where is the serous fluid located and what produces it? (Remember from the beginning of the semester...?Be able to describe the 3 layers of the heart wall. Which one is most superficial? Deep?What is each layer composed of?Which one is responsible for the heart’s ability to pump blood? [Hint: It’s the only layer made of “contractile” material.]Be able to arrange the pericardial and heart layers from superficial to deep, as shown on Slide 18.Where is the serous fluid located? What is its purpose?Be able to locate on a figure and describe the function (if mentioned in the PowerPoint) the following heart structures:anterior interventricular sulcusaortic semilunar valveauricle (right and left)chordae tendineaecoronary sulcus (right and left)left atrioventricular valve (aka bicuspid valve; aka mitral valve)left atriumleft ventricleposterior interventricular sulcuspulmonary semilunar valveright atrioventricular valve (aka tricuspid valve)right atriumright ventriclevalve cusps (leaflets)Heart Valve Disease Animation (Slide 34)What is heart valve disease?What 3 factors can cause heart valve disease?What 2 effects on valve function can be caused by heart valve disease?Why is this bad for the heart?What are the 2 types of heart valve disease?Describe each type. Which 2 heart valves most commonly have problems?Describe heart valve stenosis and heart valve regurgitation. What 3 structures drain blood into the right atrium? Where is this blood coming from in each case? Is the blood oxygenated or deoxygenated?What 4 structures bring blood to the left atrium? Where is this blood coming from in each case? Is the blood oxygenated or deoxygenated?When is the right atrioventricular valve forced closed? Why? [You might have to watch the animation on Slide 50 to better understand this)Be able to located on a figure and describe the function (if mentioned in the PowerPoint) the following heart structures [some parts are repeated from #15]:anterior interventricular arteryanterior interventricular sulcusaortic semilunar valveapex of the heartascending aortabase of the heartchordae tendineaecircumflex arteryconus arteriosuscoronary arteries (left and right)coronary sinuscoronary sulcus (right and left)great cardiac veininterventricular septumleft atrioventricular valve (aka bicuspid valve; aka mitral valve)left atriumleft ventricleligamentum arteriosummiddle cardiac veinpapillary musclesposterior interventricular arteryposterior interventricular sulcuspulmonary semilunar valvepulmonary trunkpulmonary veinsright atrioventricular valve (aka tricuspid valve)right atriumright marginal arteryright ventriclesmall cardiac veintrabeculae carneaevalve cusps (leaflets)Animation: Blood Flow through the Heart Video (Slide 50)Which side of the heart pumps out oxygen-poor (deoxygenated) blood? Where does this blood go? Why?Which side of the heart has a lower pressure overall? Why?Which side of the heart pumps out oxygen-rich (oxygenated) blood? Where does this blood go? Why?Which side of the heart has a higher pressure overall? Why?Be able to trace the flow of blood through the heart! You should be able to put the following structures in order, starting with blood returning to the heart:aortaaortic semilunar valveleft atrioventricular valve (bicuspid valve; mitral valve)left atrium left ventriclelungspulmonary arteriespulmonary semilunar valvepulmonary trunkpulmonary veinsright atrioventricular valve (tricuspid valve)right atriumright ventriclesuperior and inferior vena cavaWhich of the heart chambers and blood vessels listed above contain oxygenated blood? Deoxygenated blood?Which term refers to cardiac muscle contraction: systole or diastole?Which term refers to cardiac muscle relaxation: systole or diastole?2580549-17988700Helpful Figures-496026578122009925052667000-133350-6223000187325013652500 ................
