Oxygen is required to break down food in order to get energy from food. Without oxygen, we'd have no energy and would not survive.
breathing
Breathing is commonly associated with living organisms, as it is essential for obtaining oxygen and removing carbon dioxide. However, there are some life forms, such as certain bacteria or single-celled organisms, that do not breathe in the same way animals do. Therefore, breathing is not considered a universal characteristic of life.
Breathing is an internal force, controlled by the diaphragm and other muscles in the respiratory system. It is a vital process that brings oxygen into the body and removes carbon dioxide, essential for sustaining life.

The process of breathing was not discovered by a single individual, as it is a natural and essential function of living organisms. The mechanism of breathing, which involves inhaling oxygen and exhaling carbon dioxide, has been a fundamental aspect of life since the evolution of organisms with respiratory systems.
A breathing machine, often referred to as a ventilator, specifically assists or takes over the breathing process for patients who cannot breathe adequately on their own. Life support, on the other hand, encompasses a broader range of medical interventions designed to sustain essential bodily functions, which may include ventilators, but also involves other systems like cardiac support, dialysis, or nutritional support. Essentially, all breathing machines can be considered a form of life support, but not all life support involves breathing machines.

Three important things on Earth are water, which sustains life; oxygen, which is essential for breathing; and biodiversity, which supports the health and balance of ecosystems.
The medulla oblongata is a crucial structure in the brainstem that is required for life. It plays a vital role in regulating essential functions such as breathing, heart rate, and blood pressure. Damage to the medulla can be life-threatening.
Oxygen is the gas used for both burning and breathing. In combustion, oxygen reacts with a fuel, producing heat and light, while in respiration, it is essential for humans and many other organisms to convert food into energy. This process of breathing in oxygen and releasing carbon dioxide is vital for sustaining life.
Agonal breathing will not support life; rescue breathing (or CPR if no pulse) is required.
