Each question is worth 10 marks. 1. Maintenance of calcium ion homeostasis is critical to neurological, cardiac and skeletal muscle function. Consider the roles of two hormones involved in the regulation of the concentration of calcium ions in the blood. Parathyroid hormone increases the concentration of calcium ions in the blood, while calcitonin decreases the concentration. Based on this information predict the body’s response to restore calcium balance if a person swallowed 100 antac...
