Oxygen sensing
Oxygen sensing is the process by which the body monitors the levels of oxygen in the blood and tissues. Specialized cells and sensors detect changes in oxygen availability, signaling adjustments in breathing, circulation, and other functions to maintain optimal oxygen levels. For example, if oxygen levels drop, sensors in the carotid arteries and brain activate responses to increase breathing rate and improve oxygen intake. This regulation is crucial for cell survival and overall health, ensuring that tissues receive adequate oxygen for energy production and proper function.
