5

W hich cham ber should be present in the flow pattern of the ex perim ent, giv en that the v essels and v alv es surrounding it are present (the cham ber was om itted from the ex perim ent for sim plicity )?

You correctly answered: an increase in flow rate, which increased the pum p rate.

You correctly answered: left atrium .

Re vie w She e t Re sult s 1

Ex plain the effect of increasing the right flow tube radius on the flow rate, resistance, and pum p rate. Your answer: flow rate will increase and resistance will decrease thus decease the work load that are generated by the heart to ov ercom e the resistance thus the pum p rate is decreased.

2

D escribe what the left and right beak ers in the ex perim ent correspond to in the hum an heart. Your answer: the left beak ers represents the pulm onary v eins, while the right represents the left atrium .

3

Briefly describe how the hum an heart could com pensate for flow rate changes to m aintain blood pressure. Your answer: by changing heart rate. W hen the heart rate increases, sam e with blood pressure. W hen the heart rate decreases, also blood pressure decreases.
