What is hypoxia in simple terms

I'm hoping someone can help me out. I'm trying to understand what hypoxia is in simple terms, and I'm having a hard time finding a straightforward answer.

Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply. It occurs when the oxygen level in the blood is lower than normal and the body's tissues and organs do not receive enough oxygen to function properly. Hypoxia can be acute (short-term) or chronic (long-term). Acute hypoxia can be caused by environmental factors such as high altitudes, while chronic hypoxia may be caused by a medical condition such as congestive heart failure or lung disease.
