oxygen is released as a by product of photosynthesis performed by plants
When hemoglobin releases oxygen and nitric oxide to tissues, nitric oxide causes blood vessels to dilate, increasing blood flow and delivering more oxygen to the tissues. This helps improve oxygen delivery and tissue function.

Apple contains an enzyme called catalase, which breaks down hydrogen peroxide into oxygen and water. If the pieces of apple are small, oxygen "clings" to the apple piece and causes it the float to the surface of the solution.
Oxygen can be prepared from sodium peroxide by heating it, which causes it to release oxygen gas. The chemical reaction involved is 2 Na2O2 → 2 Na2O + O2. The oxygen gas can then be collected and used for various applications.
An oxygen meter measures the amount of oxygen from the pulse in a finger by being placed on an individuals fingertip which causes two wavelengths to be able to pass through the individual to a photo detector.
oxygen causes metal to rust oxidate
the lungs causes oxygen from the water to diffuse into the blood

When iron mixes with oxygen, it causes iron oxide, commonly known as rust. Therefore it causes the rock to "rust".
Bodies don't produce oxygen. we breathe it in.
When you are sleepy or drowsy the lungs do not take enough oxygen from the air. This causes a shortage of oxygen in our bodies. The brain senses this shortage of oxygen and sends a message that causes you to take a deep long breath---a YAWN.
