Which of the following statements is / are FALSE? (select all appropriate)Question 45Answera.During inhalation, air enters the lungs by moving down its pressure gradient, from an area of higher pressure outside the body to an area of lower pressure within the lungs.b.During forced breathing, both inhalation and exhalation are active processes that make use of muscle contractions.c.Pressure and volume are inversely related (Boyle's law)d.During exhalation, air exits the lungs by moving against its pressure gradient, from an area of lower pressure within the lungs to an area of higher pressure outside the bodye.The contraction of the diaphragm and external intercostal muscles is the first step of
