The smallest bronchioles end in tiny air sacs, called alveoli. They inflate when a person inhales and deflate when a person exhales. During gas exchange oxygen moves from the lungs to the bloodstream.
Explanation:
Loud noise can damage cells and membranes in the cochlea. Listening to loud noise for a long time can overwork hair cells in the ear, which can cause these cells to die. The hearing loss progresses as long as the exposure continues. Harmful effects might continue even after noise exposure has stopped.

Answer:
3. "It is all right to use an electric razor for shaving only if I leave it plugged in for a short time."
Explanation:
Oxygen therapy refers to the administration of supplemental oxygen in order to increase or maintain oxygen saturation above 90%, thus correcting the damage caused by hypoxemia. This technique has as its main objective to increase the oxygen level that is exchanged between the blood and the tissues.
Home oxygen administration is a very important item to guide patients and families. This is because most of the time the use of oxygen is done through the use of torpedoes that will be inside the patient's home. Thus, all procedures related to the torpedo location in the patient's home, contact with heat, solutions and fire, in short, all the risks involved with home oxygen administration are fully demonstrated and directed to all those who remain in the patient's home. patient, including nursing.
Electronic braces used near the patient's face with oxygen therapy should also be avoided, as they can cause damage to the tube that is close to the patient's face, as their use causes them to become hotter and this is very dangerous for those who undergo treatment with oxygenation. For this reason, a patient who says "It is all right to use an electric razor for shaving only if I leave it plugged in for a short time" shows that he is not well informed about oxygen therapy and needs more information.
