Problem
A. What is the primary function of the respiratory system?
B. Use a simple labelled diagram to describe the structure 10. Why do you think mass (kg) is in and VO2max (mL/kg/min)? Of the human respiratory system?
C. The human respiratory system has a number of built-in safety features to protect the lungs from foreign matter. Describe these features and explain how they protect the lungs.
D. What physical characteristics of the alveoli make them ideal structures for gas exchange? Explain why. % 405 % 30 20 0% 10% blood.
E. Describe and explain how negative pressure works in the human respiratory system?
F. Describe and explain the responses in the respiratory system when you start to exercise?
G. Explain the difference between total lung capacity and oxygen into the blood? What would happen to o gill if blood flow continue. Explain your reasoning. vital capacity?
H. During normal breathing, only a small proportion of the total lung capacity is used. How is this a survival feature?
I. Why do you think mass (kg) is included in the unit for VO2 and VO2max (mL/kg/min)? K m? K/U ructure
J. Examine Figure 11, which shows how oxygen would diffuse from water to blood if both water and blood were flowing in the same direction. Compare this with gas exchange in fish, where blood flows in the opposite ation s of the direction of water flow over the gills?
