Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the primary breathing apparatus?SCUBA (Self-Contained Underwater Breathing Apparatus), utilizing compressed air or specialized gas mixtures
2. What is the key physiological challenges?Ambient pressure increase, risk of decompression sickness, nitrogen narcosis, and thermal regulation
3. How do scuba divers breathe underwater?Scuba divers use a device called a regulator that gives them air from a tank at the pressure of the water around them, so they can breathe normally while they dive.
4. Why do divers need to stop when they come back up?When divers go down, the air in their bodies turns into bubbles if they rise too fast. Stopping at certain depths lets those bubbles safely leave the body, preventing a sickness called the bends.

Decompression Sickness: A condition caused by rapid ascent from depth, leading to gas bubbles in tissues.
Nitrogen Narcosis: A reversible intoxicating effect of breathing nitrogen under high pressure.
Saturation Diving: A technique where divers live in a pressurized environment for extended periods to work at great depths.
