Food is digested, or broken down, so that the nutrients can be extracted for use by the body as it passes through the digestive system. If food wasn't digested you would not have energy required to run vital chemical reactions and eventually resulting death
<h2>Performance of jaw-thrust maneuver</h2>
Explanation:
- The medical emergency services provide medical facilities to individuals. The service can be provided in case of accidents, sudden injury, heart attack, and other medical situations.
- The individual should provide the emergency first aid that prevents the individual tongue from the obstruction of his upper airways. The maneuver is mainly performed on the supine patient. This first aid provides the proper oxygen in the patient's body.
- The occluded teeth typically forestall progress ahead of the mandible, and the thumbs must discourage the mentum while the fingers hold mandible and lift it upward. This results in the mandibular teeth projecting before the maxillary teeth (after the mouth opens slightly)
Im not 100% sure but the best answer I can give is Prokaryotes because they came to be around the time oxygen did as well.
