Question
Use the following image to answer questions 1-4. Calculate the stroke volume (in mL per beat). Calculate the cardiac output in L/min Which of the following statements about the point labelled F in the diagram are true? Choose all of the correct answers. F occurs at the end of isovolumetric relaxation F occurs at the end of isovolumetric contraction At the point in the cardiac cycle when the volume of blood in the right ventricle is volume F, then the volume of blood in the left ventricle is also volume F. At the point in the cardiac cycle when the volume of blood in the right ventricle is volume F, then the volume of blood in the left ventricle is less than F. At the point in the cardiac cycle when the volume of blood in the right ventricle is volume F, then the volume of blood in the left ventricle is greater than volume F.Explanation / Answer
Stroke volume ; Is the blood pumped from left ventricle of heart per beat The stroke volume of blood in the ventricle at the end of a beat which is End systolic volume, from the volume of blood just prior beat End diastolic beat .It is important determinant of cardiac output , which is product of stroke volume and heart rate, and also called ejection fraction which is stroke dividing by end diastolic volume .
SV equal to EDV - ESV
SV equal to me 450-350 which is 100.
cardiac out put ;
cardiac output equal to stroke volume *heart rate
100*72 beats per min which is 7200 l/min
1. F occurs at iosmetric volume contraction
at the point in the cardiac cycle when the volume of blood in the right ventricle is voulume F ,then the voulme of blood in the left ventricle is greater than volume .
