Hyperbole is a figure of speech that involves exaggerated statements or claims not meant to be taken literally. It is used to emphasize a point or create a strong impression by overstating something beyond its normal limits. For example, saying "I have told you a million times" is an exaggeration meant to stress the speaker's frustration with repetition. Hyperbole adds emphasis and can make descriptions more vivid or dramatic.

Nausea is the feeling of discomfort in the stomach that often comes before vomiting. It can be caused by various factors, such as motion sickness, eating something that disagrees with one's stomach, or as a side effect of medications or medical treatments like chemotherapy. Nausea may also be a symptom of an underlying condition like a stomach virus or food poisoning. Treatment for nausea depends on the cause and may include medication, changes in diet, or other treatments to help ease the feeling of sickness.

Bronchitis is a condition where the air passages in the lungs, called bronchial tubes, become swollen and irritated. It can be caused by viruses or bacteria, often developing after a cold or respiratory infection. Symptoms of bronchitis may include coughing, wheezing, chest discomfort, and production of mucus. While mild bronchitis typically resolves on its own within a few weeks with rest and plenty of fluid intake, serious bronchitis can be a long-term condition and may require medical treatment to manage symptoms and prevent complications. Treatment may involve over-the-counter medications to relieve cough and fever, inhalers to open up the airways, and antibiotics if the cause is bacterial. Quitting smoking and avoiding exposure to irritants such as air pollution or dust can help prevent bronchitis.

The bronchus, also known as a bronchial tube, is a primary airway in the human respiratory system that carries air from the trachea into the lungs. It branches off into smaller bronchi, which further divide into bronchioles, allowing for the distribution of air to the different regions of the lungs. The bronchus is lined with ciliated cells and mucus-producing cells that help to filter and moisten the air, ensuring optimal lung function and gas exchange.
