B) Pulmonary vascular resistance decreases, pulmonary blood flow decreases, left atrial volume and pressures increase, and right atrial pressures decrease.
C) Pulmonary vascular resistance increases, pulmonary blood flow increases, left atrial volume and pressures decrease, and right atrial pressures increase.
D) Pulmonary vascular resistance increases, pulmonary blood flow decreases, left atrial volume and pressures decrease, and right atrial pressures increase.
