Please answer to the part A,B,C of the question below In a normal respiratory cycle the volume of air that moves into and out of the lungs is about 494 mL. The reserve and residual volumes of air that remain in the lungs occupy about 1980 mL and a single respiratory cycle for an average human takes about 4 seconds. Find a model for the total volume of air Vt) in the lungs as a function of time. 01050- 34)...
Breathing is cyclic and a full respiratory cycle from the beginning of inhalation to the end of exhalation takes about 5 seconds. The maximum rate of air flow into the lungs is about 0.5 L/s. This explains, in part, why the function f(t)=1/2sin(2πt/5) has often been used to model the rate of air flow into the lungs. This can then be used to show that the volume of inhaled air in the lungs at time t is given by V(t)=5/4π[1−cos(2/5...
Breathing is cyclic and a full respiratory cycle from the beginning of inhalation to the end of exhalation takes about 3 s. The maximum rate of air flow into the lungs is about 0.4 L/s. This explains, in part, why the function f(t)= has often been used to model the rate of air flow into the lungs. Use this model to find the volume of inhaled air in the lungs at time t.

Joe Smith is a 69-year-old male with a 50-year history of smoking 2 packs of cigarettes a day (i.e. 100-pack-year smoking history). Over the past 5 years, he has become increasingly short of breath. At first, he noticed this only when exercising, but now he is even short of breath at rest. Over the past two years, he has had several bouts of lower respiratory tract infection treated successfully with antibiotics. His shortness of breath hasn't subsided, and his breathing...
