CO2 + H2OH2CO3H+ + HCO3-The reaction above take place in the red blood cell. Infer what happens when the red blood cell is in an area of high concentration of CO2The reaction remains unchangedThe reaction move to the leftThe red blood cell shrinkThe reaction move to the right2. What is the function of the Respiratory System?To allow gas exchange to provide parts of the body with oxygen.Send signals through the spinal cord and brain to tell other parts of the body what to do.To take in glucose and convert it into useable energy.Take waste products and take them out of the body.3. What units are used to describe the measure of Atmospheric Pressure?Mm (Millimetres)Ng (Nanograms)MmHg (millimetres of mercury)Cm (Centimetres)4. Concentration of oxygen is __________ in the lungs and __________ in the tissues.High, highLow, highLow, lowHigh, low5. What is Asthma?When you have difficulty breathingWhen your lungs start to deteriorateInflammation of the ThroatInflammation of the inner nose6. Small air sacs in the lungs where many capillaries exchange carbon dioxide for oxygen taken into the body.TracheaAlveoliBronchiSinuses7. Which of the following statements is TRUENone of the aboveNumber of cigarettes smoked per day is indirectly proportional with the risk of lung cancerCarbon monoxide in tobacco increase the risk of fatty deposits in walls of arteries.Tar is a additive drug found in tobacco.8. Which of the following does not describe the adaptations of a Red Blood Cell?One cell thickBiconcave shapeContains haemoglobinHave an iron-containing structure9. A large muscle that separates the chest cavity from the abdominal cavity and helps with breathing. EpigottiLarynxTracheaDiaphragm10. Small spaces in the skull thought to regulate the temperature and humidity of the air taken into the body.LyrnxAlveoliTonsilsSinuses11.

Oxygen is transported in the blood by binding to?PlasmaWaterHaemoglobinWhite Blood Cells13. What are the parts of the Respiratory System?Trachea, Larynx, Pharynx, Bronchi, Bronchioles, Alveoli, Nasal Cavity, HeartIntercostal Muscles, Lungs, Trachea, Larynx, Pharynx, Bronchi, Bronchioles, Alveoli, Nasal CavityThroat, Bronchioles, Bronchi, Alveoli, Stomach, RibsLungs, Alveoli, Ribs, Liver Lungs,14. How is carbon dioxide transported in the blood?Binding with haemoglobinBinding to white blood cellsBy combing with water in the plasma to produce bicarbonateBinding to plasma15. Name Structure D and EBronchiole, BronchiAlveoli, BronchusBronchus, BronchioleBronchi, Bronchiole16. The Pharynx controls your speakingTrueFalse17. __________ are two air tubes branching off form the trachea and carrying air to the lungsepigottitrancheabronchilarynx18. This tube carries air down to the windpipe.PharynxSinusesBronchiLarynx19. Dome shaped muscle at the bottom of the lungs is the __________.(leave answer in lower case)20. Which vessel(s) carry deoxygenated blood to the lungs?Right and Left Pulmonary veinsSuperior and Inferior Vena CavaLeft and Right Pulmonary ArteriesPulmonary Capillaries21. Which of the following statements is FALSENumerous alveoli help increase surface area to volume ratio facilitates exchange of gases.A thin film of moisture covering the surface of the alveolus allows membranes to slide over each other easily during breathing.Alveoli walls is one cell thick which increase the rate of diffusion of gases.Alveoli is well supplied with blood capillaries.22. Oxygen rich blood is pumped out of which chamber of the heart into the aorta?Left AtriumRight AtriumRight VentricleLeft Ventricle23. What are the common effects of Emphysema and Chronic bronchitis?Airway block making breathing difficultSurface area for gaseous exchange decreasesNone of the aboveExcessive mucus is secreted by the epithelium24.
