Hey RAB,

  We have two main pipes in our throat. One is the trachea, which is used to breathe and the other is the esophagus, in which we swallow food and drink. When something goes down your trachea instead of the esophagus, we immediately start coughing. This is called aspiration. So, gulping is a way the body acts, to stop that from happening.  


When you exercise, your heart rate speeds up and your muscles work faster. These actions create a lot of heat in your body. To cool yourself off, you begin to sweat, which causes water and salts from your body to seep out of your pores. When the water and salts evaporate, the extra air cools you off. While this is a natural reaction, when you finish exercising, the sensors in your kidneys detect you have lost water. As a result, you may begin to feel thirsty.
