1.The “bends” or decompression sickness is a form of air embolism. When scuba or deep sea divers are under higher pressure, more nitrogen gas dissolves in the blood and tissue fluids. Usually a slow ascent to the surface (lower pressure) allows the gas to be gradually dissipated and exhaled. If a diver rises to the surface too rapidly, the gas comes out of solution, forming bubbles or gas emboli in the circulation. Explain why ischemia and pain may occur in various tissues such as muscle, joints, or the heart.

2.Describe the various causes of vomiting and the vomiting process.
