Respiration Quizzes & Trivia

Respiration has two definitions. In biology it means the process the process through which nutrients are converted into useful energy in a cell of an organism. What is the physiological definition of respiration? Here we are only concerned with respiration in biological terms. There are two types of respiration: aerobic respiration and anaerobic respiration.
 
In the former, oxygen and glucose react together in cells to produce water and carbon dioxide. Anaerobic respiration takes place in the absence of oxygen. Name the products of anaerobic respiration. As can be seen, respiration is actually a chemical reaction. How do aquatic animals extract oxygen from water? Is respiration the same as breathing? If you think you are good in biology, answer these quizzes on respiration to test your knowledge.

How Well Do You Know About Human Respiration? Respiration is the act in which the body takes in oxygen from the outside environment into the tissues in the body and then removes carbon dioxide from the tissues into the external...

  • Sample Question
    A 73-year-old man with hypertension, coronary artery disease, and diabetes mellitus presents to your office complaining of cough and shortness of breath. He reports that for the past 3 or 4 days, he has been experiencing progressive dyspnea on exertion, and he now has mild dyspnea at rest. He also states that he has been having fevers, chills, and purulent sputum production over this period. He denies having come into contact with anyone who was sick. Results of physical examination are as follows: blood pressure, 124/87 mm Hg; heart rate, 95 beats/min; respiratory rate, 26 breaths/min; temperature, 101.3° F (38.5° C); and oxygen saturation on room air, 88%. The patient exhibits tachypnea without the use of accessory muscles. Bronchial breath sounds are noted over the right lower lung zones consistent with consolidation. A chest radiograph in the office confirms a right lower lobe infiltrate. You plan to admit the patient to the hospital for intravenous antibiotics and further monitoring.   Which of the following is a likely cause of this patient's low oxygen saturation?

Good Luck!!
