Include proper values on the x & y-axis as well as labeling those. Make sure to label ESV, EDV, aortic and mitral valve opening and closing, and Isovolumetric relaxation and contraction where possible on the diagrams regarding blood volumes and pressure. You also need to make sure to list or provide explanation where necessary or where it is asked in the tasks.
Case Studies Tasks:

Ashor has been putting himself through a strict diet and exercise regiment. In the last week, he was feeling some irregularity in his heart rate and heart beat. He decided to visit a doctor and found that he was suffering from Hyperkalemia. Use a diagram to explain how Hyperkalemia impacts cardiac pacemaker and contractile cells. The key here is to consider resting membrane potentials and how that impacts slow and fast acting ion channels in the cardiac conduction process. Make sure to include the following items at a minimum in the diagram(s):
- mV (Membrane Potential in milivolts)
- Na+
- K+
- Ca+
- Slow acting channels
- Fast acting channels
- -40mV
- -60mV
- -90mV
- Pacemaker potential
- Depolarization
- Repolarization
- Hyperpolarization
- Absolute Refractory Period
