Subject           Heart Rate                  Stroke volume                    CO          

1                      50                                            100                              ____(A)______

2                      30                                            80                                ____(B)______

3                      60                                __    __(C)______                               7200

4                      _(D)_                                       45                                            900

Answer 1

1. Cardiac output = Heart rate $\times$ stroke volume

                             = 50 $\times$ 100

(A) is 5000

2. Cardiac output = Heart rate $\times$ stroke volume

                             = 30 $\times$ 80

(B) is 2400

3. Stroke volume = cardiac output $\div$ heart rate

                            = 7200 $\div$ 60

(C) is 120

4. Heart rate = cardiac output $\div$ stroke volume

                     = 900 $\div$ 45

(D) is 20
