When afterload increases, the heart has to work harder to push blood out. This makes it more difficult to eject blood, so stroke volume decreases. As a result, cardiac output may also decrease if the heart cannot compensate.<\/div>\n","introduction":""},"keywords":[{"options":{"points":1,"occurrences":1,"caseSensitive":true,"forgiveMistakes":false,"feedbackIncludedWord":"keyword","feedbackMissedWord":"none"},"keyword":"reduce stroke volume","alternatives":["decreases stroke volume","decreases SV","decreased stroke volume","stroke volume decreases"]},{"options":{"points":1,"occurrences":1,"caseSensitive":true,"forgiveMistakes":false,"feedbackIncludedWord":"keyword","feedbackMissedWord":"none"},"keyword":"decreases cardiac output","alternatives":["decreases CO","decreased cardiac output","cardiac output decreases"]}],"overallFeedback":[{"from":0,"to":100}],"behaviour":{"inputFieldSize":"10","enableRetry":true,"ignoreScoring":false,"pointsHost":1,"linebreakReplacement":" "},"checkAnswer":"Check","submitAnswer":"Submit","tryAgain":"Retry","showSolution":"Show solution","feedbackHeader":"Feedback","solutionTitle":"Sample solution","remainingChars":"Remaining characters: @chars","notEnoughChars":"You must enter at least @chars characters!","messageSave":"saved","ariaYourResult":"You got @score out of @total points","ariaNavigatedToSolution":"Navigated to newly included sample solution after textarea.","ariaCheck":"Check the answers.","ariaShowSolution":"Show the solution.
