Lymph tissue and lymph nodes that protect the body from infection: Adenoids and tonsils Bronchi and trachea Alveoli and sinuses None of these 5. Concentration of oxygen is __________ in the lungs and __________ in the tissues. Low, low Low, high High, low High, high 6. Which of the following statements is FALSE Alveoli walls is one cell thick which increase the rate of diffusion of gases. A thin film of moisture covering the surface of the alveolus allows membranes to slide over each other easily during breathing. Numerous alveoli help increase surface area to volume ratio facilitates exchange of gases. Alveoli is well supplied with blood capillaries. 7. What exactly happens that allows you to breathe? A contracts allowing I to let air out A contracts letting air into the lungs E lets air into lungs then C takes in Hydrogen D contracts letting air into lungs 8. What is Bronchitis? Inflammation of the Bronchial Tubes Inflammation of the spine Inflammation of the Mouth Inflammation of the Lungs 9. Gaseous exchange occurs at alveoli and cellular level using what principle? Transport Convection Osmosis Diffusion 10. These carry air into the lungs. None of the above Sinuses Bronchi and bronchiole tubes Alveoli 11. Which of the following statements is TRUE Only diaphragm, intercostal muscles and sternum, is involved in inhalation and exhalation Changes of the volume of cavity are workings of only the intercostal muscles and diaphragm. Sternum move upward and forward exhalation. During inhalation, external intercostal muscles relax and internal intercostal muscles contract. 12. Tiny sacs at the farthest end of the smallest airways are _________ which also branch off the bronchioles.(leave answer in lower case) alveoli 13. What percentage of Oxygen makes up air? 31% 21% 50% 40% 14. Which of the following does not describe the adaptations of a Red Blood Cell? Have an iron-containing structure One cell thick Biconcave shape Contains haemoglobin 15. __________ smaller branches that branch off the bronchi into the lungs.(leave answer in lower case) 16. External respiration can be described as? The passive process of exhalation The exchange of gases at a cellular level within the body The active process of inhalation The exchange of gases at alveoli level within the lungs 17. Air comprises the following components? Oxygen, Carbon Dioxide, Natural Gas and Helium Oxygen, Carbon Dioxide, Nitrogen and Natural Gas Oxygen, Carbon Dioxide, Nitrogen and Water Vapour Oxygen, Carbon Dioxide, Water Vapour and Natural Gas 18. From the equationCO2 + H2OH2CO3H+ + HCO3-____________ is the enzyme which catalyze the formation of _______________. Carbonic catalase, carbonic acid Carbonic anhydrase, hydrogencarbonate ions Carbonic catalase, hydrogencarbonate ions Carbonic anhydrase, carbonic acid 19. Small air sacs in the lungs where many capillaries exchange carbon dioxide for oxygen taken into the body. Alveoli Bronchi Trachea Sinuses 20. Movement of air in and out of the lungs is due to _______ Diaphragm contracts and flattens Inhalation & Exhalation External intercostal muscles contract and internal intercostal muscles relax Difference in pressure 21. Which of the following statements is FALSE C-shaped rings of cartilage are specialized structures of the trachea Cilia in the trachea helps in breathing, to sweep air into the lungs Glands cells secreting mucus help trap dust particle in the trachea Heart is found in the thoracic cavity 22. Which of the following statements is TRUE None of the above Number of cigarettes smoked per day is indirectly proportional with the risk of lung cancer Carbon monoxide in tobacco increase the risk of fatty deposits in walls of arteries. Tar is a additive drug found in tobacco. 23. The Pharynx controls your speaking True False 24. Carbon monoxide is a chemical found in tobacco smoke.
