Source google Respiratory System Lung Model Grade: 5th Rational: Students can’t look inside their chest and observe how their lungs work. After making a working model of the respiratory system students can connect what they read about the respiratory system with what they see. Prior Knowledge: Students have read aloud a respiratory system chapter from their science book‚ "Discovery Works" in class. Students should know the parts of the respiratory system and the basics of how it operates

Anatomy of the Respiratory System Nose and Nasal Cavity The nose and nasal cavity form the main external opening for the respiratory system and are the first section of the body’s airway—the respiratory tract through which air moves. The nose is a structure of the face made of cartilage‚ bone‚ muscle‚ and skin that supports and protects the anterior portion of the nasal cavity. The nasal cavity is a hollow space within the nose and skull that is lined with hairs and mucus membrane. The function

Acute bronchitis often occurs during the course of an acute viral illness such as the common cold or influenza. Viruses cause about

Introduction to Measurement Mass‚ Length‚ and Volume Introduction Much of what we know about the physical world has been obtained from measurements made in the laboratory. Skill is required to design experiments so that careful measurements can be made. Skill is also needed to use lab equipment correctly so that errors can be minimized. At the same time‚ it is important to understand the limitations of scientific measurements. Concepts Measurement Significant figures Accuracy

oxygen and respiratory disease. Respiratory disease is the term used for defining diseases like chronic obstructive pulmonary disease (COPD)‚ emphysema and asthma. Common signs and symptoms of respiratory disease are coughing‚ wheezing‚ dyspnoea and production of abnormal secretions like sputum and haemoptysis (Jenkins et al 2008). Respiratory disease accounted for 8.4% of the registered deaths in Australia in 2007. There was an estimated 6.6% increase in deaths caused by respiratory disease from

One might think that breathing is just an involuntary movement‚ but for the millions of people who suffer from respiratory illnesses‚ each and every breath is a major accomplishment to another day of daily life. The respiratory system not only oxygenates the blood for the body‚ but also filters out wastes‚ infections‚ and provides the air that is needed for daily speech. The respiratory system
