Give an explanation of the relationships between breathing and respiration. Is there a resemblance? Explain why you came to that conclusion.
Step by step
Solved in 2 steps
- Where is an accidentally inhaled object, such as a peanut or a small piece of toy, likely to lodge in the lungs? Explain your answer.In the model lung demonstration, the bell jar does not change in size. Describe the changes in the corresponding human respiratory system structures during inhalation and exhalation.The two lungs of human are not identical size. Why?
- When considering the limitations of external respiration, explain why animals larger than flatworms require specialized structures for ventilation. List two examples of these specialized structures.Patients with severe cases of COVID-19 (the disease caused by the coronavirus) may not be able to breathe on their own and so need mechanical ventilation. This condition occurs when the virus attacks the lining of the lungs, resulting in a buildup of fluid and dead cells in the alveoli. Using your knowledge of the anatomy and function of human lungs, explain why this condition makes it difficult for adequate gas exchange to occur. please helpExplain what caused the trend that you observed when you plotted duration of voluntary apnea as a function of alveolar minute volume. Note you need to EXPLAIN why you saw the pattern, not just repeat the answer to the question above!
- In the model lung demonstration, air flows into the balloons through a rigid tube that divides once. Compare the rigidity and the number of branches of the conducting structures in the model to the rigidity and number of branches of the conducting structures in the human respiratory system.Use the table provided to show that the air travels a total distance of 273 mm from the trachea to the alveolitrace an oxygen molecule from the air outside the nose through the respiratory passageways to the pulmonary alveolus. Then trace the carbon dioxide molecule back to the air outside the nose
