Boyle\'s law can be used to explain part of the process by which air enters and leaves the lungs during breathing. Which of the following statements are true
1- When the diaphragm is lowered, volume decreases and pressure increases.
2- During inhalation, the diaphragm is raised, increasing the pressure in the lungs and allowing air to flow into the lungs.
3-During exhalation, the diaphragm is raised, increasing the pressure in the lungs and resulting in air being forced out of the lungs.
4-A decrease in volume results in an increase in pressure
