Respiratory System Lecture Exam Questions With 100% Correct Answers 2024 Your body couldn't breathe without this system a) Integumentary system b) respiratory system c) circulatory system d) urinary system - Correct Answer-b. respiratory system The transfer of oxygen and carbon dioxide takes place at the a) hilum of the lung b) main bronchus c) respiratory membrane d) carina of the trachea - Correct Answer-c. respiratory membrane When you inhale a) your diaphragm contracts, lung volume increases b) diaphragm relaxes, lung volume increases c) diaphragm contracts, intrapleural pressure decreases d) diaphragm relaxes, intrapleural pressure increases e) diaphragm contracts, atmospheric pressure decreases - Correct Answer-a. your diaphragm contracts, lung volume increases The main function of the nasal conchae is to a) increase surface area to allow more air movement b) warm air and remove water c) to separate the nasal cavity from the oral cavity d) trap pathogens and debris - Correct Answer-a. increase surface area to allow more air movement In the transfer of oxygen and carbon dioxide, what do these molecules bind to on the red blood cell a) the antigen b) cell membrane c) membrane receptors d) the antibody e) hemoglobin - Correct Answer-e. hemoglobin Gas exchange between the blood and tissue cells is referred to as Which term does not belong? a) Nasal cavity b) Trachea c) Larynx d) Alveolus e) Bronchus - Correct Answer-d. alveolus Which term does not belong a) Apex b) Larynx c) Base d) Pleura e) Hilus - Correct Answer-b. larynx Which term does not belong? a) Peritonitis b) Sinusitis c) Pleurisy d) Tonsillitis e) Laryngitis - Correct Answer-a. peritonitis Which term does not belong? a) Alveoli b) Respiratory zone c) Alveolar sac d) Alveolar duct e) Primary bronchus - Correct Answer-e. primary bronchus respiratory volume inhaled or exhaled during normal breathing - Correct Answer-Tidal Volume total amount of exchangeable air - Correct Answer-vital capacity amount of air that can still be exhaled after a normal exhalation - Correct Answer-residual volume gas volume that allows gas exchange to go on continuosly - Correct Answer-expiratory reserve volume air in respiratory passages that does not contribute to gas exchange - Correct Answer-dead space volume Condition characterized by fibrosis of the lung and an increase in size of the alveolar chambers - Correct Answer-Emphysema Lack or cessation of breathing - Correct Answer-Apnea Normal breathing in terms of rate and depth - Correct Answer- Eupnea Labored breathing, or air "hunger" - Correct Answer-Dyspnea Chronic oxygen deficiency - Correct Answer-Hypoxia Bluish discoloration (mucus membrane) due to oxygenation of blood - Correct Answer-Cyanosis Respiratory passageways narrowed by bronchiolar spasms - Correct Answer-Asthma b. Trachea - Main bronchi - Lobar bronchi - Segmental bronchi - Bronchioles - Terminal bronchioles c. Trachea - Main bronchi - Bronchioles - Segmental bronchi - Lobar bronchi - Terminal bronchioles d. Trachea - Main bronchi - Segmental bronchi - Bronchioles - Lobar bronchi - Terminal bronchioles - Correct Answer-b. Trachea - Main bronchi - Lobar bronchi - Segmental bronchi - Bronchioles - Terminal bronchioles Internal respiration is defined as: a) breathing b) oxygen and carbon dioxide to and from tissue cells and lungs c) oxygen diffuses from lungs to blood, and carbon dioxide diffuses from blood to lungs d) oxygen diffuses from blood to tissue cells, carbon dioxide diffuse from tissue cells to blood - Correct Answer-d. oxygen diffuses from blood to tissue cells, carbon dioxide diffuse from tissue cells to blood External respiration is defined as: a) breathing b) oxygen and carbon dioxide to and from tissue cells and lungs c) oxygen diffuses from lungs to blood, and carbon dioxide diffuses from blood to lungs d) oxygen diffuses from blood to tissue cells, carbon dioxide diffuse from tissue cells to blood - Correct Answer-c. oxygen diffuses from lungs to blood, and carbon dioxide diffuses from blood to lungs Pulmonary ventilation is defined as: a) breathing b) oxygen and carbon dioxide to and from tissue cells and lungs c) oxygen diffuses from lungs to blood, and carbon dioxide diffuses from blood to lungs d) oxygen diffuses from blood to tissue cells, carbon dioxide diffuse from tissue cells to blood - Correct Answer-a. breathing The upper respiratory tract includes all of the following except: a) trachea b) nasal cavity c) larynx d) glottis - Correct Answer-a. trachea The Respiratory zone includes all of the following except: a) alveolar sac b) terminal bronchioles c) alveolar ducts d) alveoli - Correct Answer-b. terminal bronchioles Pressure of air outside the body - Correct Answer- Atmospheric pressure If this pressure becomes equal to the atmospheric pressure, the lungs collapse - Correct Answer-Intrapleural pressure As it decreases, air flows into the passageways of the lungs - Correct Answer-Intrapulmonary pressure In healthy lungs, it is always lower than atmospheric pressure - negative pressure - Correct Answer-Intrapleural pressure
