- Which one of the following is a possibility for most of us in regard to breathing, by making a conscious effort? (a) One can breathe out air totally without oxygen. (b) One can breathe out air through Eustachian tube by closing both nose and mouth. (c) One can consciously breathe in and breathe out by moving the diaphragm alone, without moving the ribs at all. (d) The lungs can be made fully empty by forcefully breathing out all air from them.

- Which of the following is TRUE of airway resistance in the respiratory system? O a) Resistance increases with increasing lung volume b) Resistance decreases with increasing lung volume Oc) Resistance decreases when bronchi are exposed to acetylcholine d) Resistance increases when bronchi are exposed to norepinephrinearrow_forwardWhich of the following is an abnormal lower airway sound associated with breathing? A) Gurgling B) Snoring C) Stridor D) Wheezingarrow_forwardUnder conditions where normal breathing isn’t sufficient, other muscles will assist the diaphragm in changing the volume of the thoracic cavity. A muscle that increases the volume of the thoracic cavity will cause pressure to (↑/↓) which means that it is helping with forced (inspiration/expiration). A muscle that decreases the volume of the thoracic cavity will cause pressure to (↑/↓) which means that it is helping with forced (inspiration/expiration).arrow_forward

How does this help to protect the lungs? 2)Polio causes a patient's intercostal muscles to be completely paralysed. What impact would this have on the patient's breathing?arrow_forward
- Which of the following landmarks are used to size an oropharyngeal airway properly? A) Tip of the nose to the far portion of the ear B) Corner of the mouth to tip of ear lobe C) Corner of mouth to top of the ear D) Center of the jaw to edge of the eararrow_forwardWhen the diaphragm and external intercostal muscles contract, which of the following actions does NOT occur? A. Air moves into lungs B. The diaphragm moves inferiorly C. The intrapulmonary pressure decreases D. The intrapleural pressure increases.arrow_forwardBoth the elastic property of the lung and the air :water interface contribute to the overall recoil of the lung. What are the relative contributions of the elastic property and the air: water interface to the recoil of the lung? A)both contribute equally to the recoil of the lung. B)the elastic tissue contributes ~33% to the recoil of the lung. C)the air:water interface contributes ~33% to the recoil of the lung. D)the elastic tissue contributes ~67% to the recoil of the lung.
