Pals can even watch your journey on a map in real-time, using the Uber app. After booking a ride, the app sends riders a photo of their driver, his license plate number and a description of the vehicle, so they know who to look for.berX drivers are required to be at least 21 or 23 years old, depending on the city, have their own insurance and a mid-size or full-size 4-door vehicle in excellent condition, according to Uberâs website.
When you inhale air through your nose or mouth, it travels down the back of your throat (pharynx), passes through your voice box (larynx) and into your windpipe (trachea). Your trachea is divided into two air passages (bronchial tubes). One bronchial tube leads to the left lung, the other to the right lung.
Nose or mouth. The nose is the best route for air to get into the lungs, as it is a better filter than the mouth. The nose decreases the amount of irritants that reach the lungs, whilst also heating and adding moisture to the air. Mouth breathing is usually needed when exercising or when more air is needed, because the nose is not the most efficient way of getting large amounts of air into the lungs. Journey down the windpipe. After entering the nose or mouth, air travels down the trachea or windpipe. The trachea is the tube lying closest to the neck. Behind the trachea is the oesophagus or food tube. Air moves down the trachea when we inhale and food moves down the oesophagus when we eat. The path air and food take is controlled by the epiglottis, a gate that prevents food from entering the trachea.
