SPIRITUS

Take a deep breath and exhale. What just happened? This week we'll be exploring the respiratory system, lung capacity, oxygen and how our lungs work as part of the circulatory system. We'll take a little trip inside the nose to find out what boogers are all about and why we sneeze. Find out how vocal cords work and if singers are better breathers than the rest of us. We'll explore the field of dentistry, teeth and a condition called sleep apnea. Learn about common breathing emergencies like choking, asthma and anaphylaxis and how you can help.
