Respiratory Mechanics 1 Note there is an error in your lab book! The starting radius for the flow tube diameter should be 5mm in each experiment and NOT 6mm.Use your computer link to ADAm for this part of this week’s lab. You are also responsible for the PowerPhys lab report. Measuring Normal Respiratory Volumes 1) Calculate the minute respiratory volume using the tidal volume and breaths per minute (pump rate). 2) Define the following terms: a. Respiration- The act of breathing

Respiratory Volumes Activity 2: Measuring Normal Respiratory Volumes 1. Minute respiratory volume: 7‚500 ml 2. Judging from the trace you generated‚ inspiration took place over how many seconds? 2 seconds 3. Expiration took place over how many seconds? 2 seconds 4. Does the duration of inspiration or expiration vary during ERV or FVC? Yes Activity 3: Effect of Restricted Air Flow on Respiratory Volumes 5. How does this set of data compare to the data you recorded for Activity

Answers 1a) On graph paper 1b) At molecular level‚ Haemoglobin is a protein made of four subunits bound together. Each of the subunits consists of a molecular group known as ‘heme’ and a polypeptide attached to the ‘heme’. The ‘heme’ group contains one atom of iron (Fe²+) and it is this iron that the oxygen molecule combines itself to. As there are four of the iron molecules in the haemoglobin this shows that a maximum of four oxygen molecules can be carried by the haemoglobin at anytime. For simplicity

The Respiratory System STRUCTURAL PLAN Basic plan of respiratory system would be similar to an inverted tree if it were hollow; leaves of the tree would be comparable to alveoli‚ with the microscopic sacs enclosed by networks of capillaries (Figure 14-1) Passive transport process of diffusion is responsible for the exchange of gases that occur during respiration. RESPIRATORY TRACTS Upper respiratory tract—nose‚ pharynx‚ and larynx Lower respiratory tract—trachea‚ bronchial tree‚ and lungs

The Respiratory System is crucial to every human being. Without it‚ we would cease to live outside of the womb. Let us begin by taking a look at the structure of the respiratory system and how vital it is to life. During inhalation or exhalation air is pulled towards or away from the lungs‚ by several cavities‚ tubes‚ and openings. The organs of the respiratory system make sure that oxygen enters our bodies and carbon dioxide leaves our bodies. The respiratory tract is the path of air from the

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
