Conscious thought processed tied to strong emotions b) B. Emotional states c) C. An anticipation of strenuous exercise d) D. Unconscious thought processed tied to strong emotions 13) The respiratory and cardiovascular systems make adjustments in response to both the intensity and duration of exercise : a) As cardiac output rises, the blood flow to the heart, termed pulmonary perfusion, increases as well. b) As cardiac output rises, the blood flow to the lungs, termed pulmonary perfusion, decreases as well. c) The oxygen diffusing capacity may increase threefold during minimal exercise. d) The oxygen diffusing capacity may increase threefold during maximal exercise. 14) Which of the following is true about the contribution of the respiratory system for all body systems ? a) • Urinary system together with the digestive system regulate the pH and body fluids. b) • Digestive system forceful contraction of respiratory muscles can assist in defecation. c) • Angiotensin-converting enzyme (ACE) in lungs catalyzes formation of the hormone angiotensin I from angiotensin II. d) • Cardiovascular system during inhalation, respiratory pumps aids return of venous blood to the lungs 15) How does the lymphatic system and immunity relate to the respiratory system ? a) • Pharynx not contains lymphatic tissue b) • Respiratory pump during exhalation promotes flow of lymph c) • Respiratory pump during inhalation promotes flow of lymph d) • Mucus in trachea contribute to specific resistance to disease 16) Which of the following is not true. a) • Elderly people easily decrease their blood oxygen level. b) • Young people decreased in alveolar macrophage activity. c) • Elderly people decreased in alveolar macrophage activity. d) • Young people increased in vital capacity. 17) How does Chronic Obstructive Pulmonary Disease (COPD) affect the body ? a) • The lining of the airways become swollen and inflammed b) • The production of mucus is decreased c) • Lung can function normally as normal person d) • Clear the airways, making it easier to breathe 18) Which of the following is true about emphysema ? a) • Cyanosis occur early in the disease b) • Airways not collapse during expiration c) • Chronic inflammation promotes lung fibrosis d) • Patients use a small amount of energy to exhale 19) Following answers are not true about the effect of chronic bronchitis diseases EXCEPT a) • Mucus production decreases b) • Risk of lung infection decreases c) • Inflammation of the mucosa of the upper respiratory passages d) • Hypoxia and cyanosis occur early 20) Which are the correct common types of cell cancer in lung cancer ? a) • I and II b) • I and IV c) • I, II and III d) • I, II and IV
