Where does gas exchange occur in the respiratory system and what exactly diffuses in and out of the blood?Lungs, Carbon Dioxide and GlucoseDiaphragm, Oxygen and Carbon DioxideLungs, Oxygen and NitrogenAlveoli, Oxygen and Carbon Dioxide3. Which of these is the job of the respiratory system?Breaking down food for it to be used by the body.Holding up the body and giving it support and shape.All of the aboveGas exchange between the external environment and the body's circulatory system.4. The diffusion of O2 and CO2 at a cellular level is described as?Gas transportExternal respirationInternal respirationGas transfer5. The flap laying between the airway and esophagus is the ___________ which close over the esophagus when breathing and over the airway when eating or drinking.nosetrancheaepiglottisnone of the above6. Which of the following statements is TRUESternum move upward and forward exhalation.Only diaphragm, intercostal muscles and sternum, is involved in inhalation and exhalationDuring inhalation, external intercostal muscles relax and internal intercostal muscles contract.Changes of the volume of cavity are workings of only the intercostal muscles and diaphragm.7. What exactly happens that allows you to breathe? E lets air into lungs then C takes in HydrogenD contracts letting air into lungsA contracts letting air into the lungsA contracts allowing I to let air out8. Which of the following statements is FALSE 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.Numerous alveoli help increase surface area to volume ratio facilitates exchange of gases.Alveoli is well supplied with blood capillaries.9. Small air sacs in the lungs where many capillaries exchange carbon dioxide for oxygen taken into the body.BronchiTracheaAlveoliSinuses10. From the equationCO2 + H2OH2CO3H+ + HCO3-____________ is the enzyme which catalyze the formation of _______________.Carbonic catalase, carbonic acidCarbonic anhydrase, carbonic acidCarbonic catalase, hydrogencarbonate ionsCarbonic anhydrase, hydrogencarbonate ions11. The _____________ is the wind pipe and filters oTracheaBronchisisAlvosisNone of the above12. What is the function of the Respiratory System?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.To allow gas exchange to provide parts of the body with oxygen.13. Which vessel(s) carry deoxygenated blood to the lungs?Pulmonary CapillariesSuperior and Inferior Vena CavaRight and Left Pulmonary veinsLeft and Right Pulmonary Arteries14. What is the pathway air takes during inhalation and exhalation? Mouth, Trachea, Stomach, LungsMouth, Trachea, LungsMouth, Lungs, TracheaLungs, Mouth15. __________ are two air tubes branching off form the trachea and carrying air to the lungstrancheaepigottilarynxbronchi16.

Which of the following statements is FALSEC-shaped rings of cartilage are specialized structures of the tracheaCilia in the trachea helps in breathing, to sweep air into the lungsGlands cells secreting mucus help trap dust particle in the tracheaHeart is found in the thoracic cavity22. Oxygen is transported in the blood by binding to?White Blood CellsWaterPlasmaHaemoglobin23. Lymph tissue and lymph nodes that protect the body from infection:None of theseAdenoids and tonsilsAlveoli and sinusesBronchi and trachea24. The Pharynx controls your speaking FalseTrue25.
