1 Name period date assigned date due date returned procedure 1. Take one balloon and stretch it out 2. Take one deep breath and blow into the balloon until you cannot breath out anymore. Do Not Take A Second Breath 3. Pinch the top closed so that no air escapes 4. have a partner put the string around the biggest part of the balloon 5. Put the string up to the ruler to determine how big the balloon is around the center. 6. Record your answer questions 1. What was the circumference of your balloon in cm? 2. How large was the smallest and largest balloons in your class (in cm)? smallest: largest: what is the range of this data? 1

2 3. Diagram the 3D lung model that s at your table. 4. Using the digital microscope and the lung slide, draw a sketch of what you see. Lung Use the Respiratory System Power Point to help you answer the following questions. organ system main organs function interacts with: respiratory system 2

3 Label the parts of the respiratory system 3

4 USE THIS DIAGRAM TO ANSWER QUESTIONS How does the structure of the alveoli help process 1 in the diagram? A small patterns on the surface of the alveoli correspond with the shapes of CO 2 and O 2 molecules and allow them to enter B smooth, rounded membranes of the alveoli allow gas molecules to flow in and our freely C the hollow interior of the alveoli has ample space for unlimited gas molecules D thin walls of the alveoli let molecules of CO 2 and O 2 pass through easily 18 What two body systems are interacting in this diagram? A respiratory-excretory B digestive-circulatory C nervous-endocrine D respiratory-circulatory 4

5 19 Study the diagram carefully. What process is illustrated in the diagram? A photosynthesis B gas exchange C respiration D gas deposition 22 What is the major role of red blood cells in the circulatory system? A carry nutrients and oxygen to body cells B prevent disease and fight infection C carry digestive juices to the stomach D send chemical messages to the nervous system 20 Identify structure 2. A vein B artery C red blood cell D capillary 23 What is the original source of O 2 in the alveoli? A heart B inhaled air C nasal passages D exhaled air 21 Identify structure 3. A vein B artery C red blood cell D capillary 24 What part of a heating and air conditioning system performs a function similar to nasal hairs? A ducts B thermostat C filter D cooling agent 5

6 25 Which statement best describes the function of this human body system? A breaks down food into nutrients and wastes B supplies O 2 to the blood, which in turn delivers O 2 to all parts of the body C endocrine and reproductive D nervous and digestive 26 This table shows approximate amounts of gases inhaled and exhaled by humans. What conclusion can you draw from this information? Gas Inhaled Air Exhaled Air nitrogen 78% 78% oxygen 21% 16% carbon dioxide 0.03% 4% A Inhaled air contains less oxygen and more carbon dioxide than exhaled air. B Inhaled air contains more oxygen and less carbon dioxide than exhaled air. C Inhaled air contains more oxygen and more carbon dioxide than exhaled air. D Inhaled air contains the same amount of nitrogen and carbon dioxide as exhaled air. 6

7 27 This diagram shows one way in which two different body systems interact. Which statement identifies the two body systems that are interacting and describes what is happening. Gases Exchanged alveoli capillaries A The alveoli in the respiratory system and the capillaries in the circulatory system are exchanging oxygen and carbon dioxide. B The alveoli in the muscular system and the capillaries of the circulatory system are exchanging oxygen and nitrogen. C The capillaries of the circulatory system and the alveoli of the excretory system are exchanging nitrogen and carbon dioxide. D The capillaries of the circulatory system and the alveoli of the nervous system are exchanging carbon dioxide and carbon monoxide. 28 Which of the following is NOT a part of the respiratory system? A diaphragm B esophagus C lungs D trachea 7
