Learning objective: Use models to explain the structure and function of the respiratory system Success criteria
The respiratory system is responsible for oxygenating our blood and removing carbon dioxide from our bodies. The main organs of the respiratory system are the nose, throat, larynx, trachea, bronchi, and lungs. The respiratory system helps us to breathe, talk, and smell.
The Respiratory System
Respiration: The exchange of oxygen and carbon dioxide between an organism and its environment. Alveoli: Tiny air sacs in the lungs where oxygen is taken in and carbon dioxide is released. Lungs: The pair of organs responsible for respiration, located in the chest cavity.
The respiratory system helps to regulate the body temperature, as it is involved in releasing heat when exhaling. The mucous membrane of the respiratory system helps to keep the lungs moist and free of dust and other particles. The respiratory system is made up of two parts: the upper respiratory tract and the lower respiratory tract.
Did you know?
Question: How would you explain the components of the respiratory system to someone who has never studied it before? Clues: • The respiratory system is composed of organs and structures that help us breathe. • It includes the nose, mouth, trachea, lungs, and diaphragm. • The respiratory system helps to deliver oxygen to the body's cells and remove carbon dioxide. In pairs: Select and solve one of the tasks: A. Work in pairs to create a diagram of the respiratory system and explain its components. B. Explain the components of the respiratory system to your partner using your own words.
