Due to a reduction in blood volume due to blood donation, the stroke volume will decrease. However, to compensate for this, your heart rate will increase so as to maintain your cardiac output. Cardiac output is stroke volume multiplied with heart rate.
Maintaining normal cardiac output is critical so the whole body receives enough nutrients and oxygen.
