Intro
The main function of the breathing system is to supply the blood with oxygen. The breathing system does this through breathing. Breathing is a natural process that we utilize to acquire oxygen, unlike consuming or drinking to get energy. When we breathe, we inhale oxygen and exhale co2. This exchange of gases is the respiratory system’s means of getting oxygen to the blood. The breathing system is responsible for taking the gases to and from the exchange surfaces of the lungs.
Many parts contribute in this procedure, such as; nose, nasal cavity, vocal cords, throat, trachea, bronchi, bronchioles, and alveoli.
Task
The anatomy and physiology of the respiratory system are extremely essential to the human body. It will provide you a broad understanding of how the body obtains oxygen, removes waste products, and the importance of its essential function in keeping individuals alive. At the end of this assignment, you must like be able to describe and discuss the structure and functions of the respiratory system in addition to label a diagram of the breathing system.
You will check out the breathing system utilizing interactive websites and likewise sites that you will take self-quizzes to inspect your understanding or memorization of the parts. This webquest is divided into 2 parts, one the anatomy of the breathing system and two the physiology of the respiratory system. Use the list below resources to finish the tasks, you might use alternative websites, but you should record the url address. Make sure that the sites you use stand; no Wikipedia or ask websites.
Try to stick to sites that are of a domain like.org,. edu,. gov.
