obtain one for this experiment? Did you correctly predict how you would measure the amount of plasma glucose in a patient sample using the glucose standard curve? _A glucose standard curve is a method for identifying blood glucose. I incorrectly predicted you would get it from the blood sample. In reality you would get it by the optical density of the sample will be measured and the glucose concentration will be extrapolated from the glucose standard curve. ______________ __________________________________________________________________

Danielle Rollins Cardiovascular Physiology Activity 1 1) Explain why the larger waves seen on the oscilloscope represent ventricular contraction. The ventricular contraction is when the blood is sent through the whole body as opposed to the atrial contraction that sends the blood to the heart and lungs. 2) Explain why the amplitude of the wave did not change when you increased the frequency of the stimulation. (Hint: relate your response to the refractory period of the cardiac action
