The document discusses the dangers of diving deep in the Mariana Trench, including lack of oxygen, high water pressure, and risks of decompression sickness when ascending or descending too quickly. It outlines symptoms of decompression sickness like joint pain, confusion, and coughing and explains recompression treatment. The text also notes how diving deeply affects the respiratory, muscular and skeletal systems through water pressure, temperature, and lack of oxygen.

1. Mariana Trench

2. Dangers Lack of Oxygen Water Pressure Rates of Ascending and Descending Hypothermal Vents Temperature

3. Decompression Sickness Happens when a diver ascends or descends to quickly Symptoms: Agrivated joints Confusion/Memory Loss Headaches Blurried vision Deep Chest pain Dry Constant cough Swelling of skin Recompression is the only effective treatment for severe Decompression Sickness With lighter cases oxygen masks and rest is effective

5. Body Systems affected Respiratory Skin/Muscle Skeletal

6. Effects on Respiratory System Pressure Temperature Lack of Oxygen Effects on Muscular System Pressure Lack of Oxygen

7. Effects on Skeletal System Pressure Descending Ascending
