Respiratory physiological Changes in Pregnancy :
TV & FRC decrease, minute ventilation increases
TV & Minute Ventilation & FRC decreases
FRC drops 18-20% due to compression of the diaphragm

External and internal intercostals muscle
Internal intercostals muscle
External Intercostal muscle and diaphragm
Regarding Lung Compliance in restrictive lung diseases
Restrictive lung disease has reduce compliance due to loss of elastic fibres
Restrictive lung disease has increase compliance due to stiffening of lung tissue
Restrictive lung disease has reduce compliance due to stiffening of lung tissue
