Q1Which muscle(s) is involved in forced exhalation.??
Q2True or False: Air will flow into the lungs when the intrapulmonary pressure is greater than atmospheric pressure.
questions3 As a general rule, vital capacity with. height and .with age.
.Q4 Which period of pulmonary ventilation is a passive process?

Expert Solution

Q. 1.which muscle involved in forced exhalation?

Answer :following muscles involved in forced exhalation,

Intercostal muscles

Abdominal muscles

Sternocleidomastoid and scalene muscle .

Q. 2.air flows into the lungs when intrapulmonary pressure is greater than atmospheric pressure.

Answer : false

Because air flow into lung when atmospheric pressure is greater than intrapulmonary pressure .

Q. 3 general vital capacity with height and age:

Height :150-155 cm

Vital capacity in cm3: 2900

Height :155-160 cm

Vital capacity in cm3:3150

Height :160-165 cm

Vital capacity in cm3:3400

Height :170-175 cm

Vital capacity :3950

Height :175-180 cm

Vital capacity :4300

Age:15-25

Vital capacity :3425

Age:25-35

Vital capacity :3500

Age :35-45

Vital capacity :3225

Age :45-55

Vital capacity :3050

Age:55-65

Vital capacity :2850

Q. 4 which period of pulmonary ventilation is passive proces?

Answer : Expiration process is passive during pulmonary ventilation as in this phase air expelled and lungs are relaxed.

Compare blood flow (perfusion) and air/water flow (ventilation) in fish gills, frog lungs, bird lungs and mammalian lungs. Consider how terms of the Fick Diffusion Equation (write out) are manifest in the design of the exchange surfaces.

Explain the relationship among vital capacity, tidal volume, forced inhalation volume, and forced exhalation volume

Consider the following combined cycle. The mass flow rate of air is 73 kg/s. Air enters the compressor at state 1 with Patm =1 atm and Tamb = 20°C. The compressor has a pressure ratio of 7.5 and an efficiency ?c = 0.85. Air enters the combustor and is heated to a temperature TH = 1250°C. The turbine has an efficiency of ?t,1 = 0.87. The air leaving the turbine enters the steam boiler where it transfers heat to the...

calculate the maximum velocity and the correspondingbvolumetric flow rate (in/cm^3/s) at which laminar flow of air and water is possible in pipes with the following diameter D=.25,.5,1.0,2.0,4.0,6.0, and 10.0in

The power (in watts) used to move air out of the lungs is equal to the air pressure (in N/m2) multiplied by the air flow rate (in m3/s). For quiet breathing (where p = 100 N/m2 and flow rate = 100 cm3/s or 1.0 x 10-4 m3/s), the power involved = 0.01 W ; for loud singing (where p = 4000 N/m2 and flow rate = 400 cm3/s or 4.0 x 104 m3/s), the power involved = 1.6 W. In...

The air mass flow rate of a jet engine is 10 kg/s. The stagnation enthalpy at the exit of the turbine is 918 kJ/kg and the excess air is 4.5. (a) What should be the mass flow rate of fuel injected in the afterburner, such that the stagnation enthalpy at the end of the afterburner is 1700 kJ/kg? (b) What is the excess air in the afterburner? (c) What is the maximum temperature in the afterburner?
