How does the body regulate adenosine build up and what impact does it have on physiological processes?

The body regulates adenosine build-up by breaking it down through enzymes like adenosine deaminase. Adenosine is a signaling molecule that affects various physiological processes, such as sleep-wake cycles, inflammation, and blood flow. When adenosine levels increase, it can lead to drowsiness, vasodilation, and suppression of immune responses.
