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 πt)] liters. Use this to compute the average volume (in liters) of inhaled air in the lungs in one respiratory cycle.
Average volume = ____________ liters

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.

Which of the following statements is correct about the process of breathing in the MAMMALIAN Respiratory System? Strong contraction of the Diaphragm exerts a positive force on the Trachea and Bronchioles, which pushes air into the lungs through positive pressure. Breathing with Lungs must be more efficient than breathing with Gills, since atmospheric air has less oxygen available, when compared to the amount of oxygen dissolved in water. During Inhalation, contraction of the Rib Muscles and Diaphragm increases the volume...

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)...

Asthma is a common breathing disease in which inflammation in the airways of the lungs causes episodes of shortness of breath, coughing, and chest tightness. Patients with asthma often have wheezing, an abnormal sound heard on exhalation due to turbulent airflow. Turbulent airflow is caused by swelling, mucus secretion, and constriction of muscle in the walls of the airways, shrinking the radius of the air passages leading to increased resistance to airflow and making it harder for patients to exhale....

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...
