This study investigates the effects of MCh and FSK on airway area and oscillatory calcium dynamics. Parameters measured include initial airway area percentages and fluorescent intensity over time, along with calcium oscillation frequencies. Key observations reveal the relationship between agonist concentration and physiological responses in airway tissues. The findings could contribute to understanding airway responsiveness and calcium signaling in bronchial smooth muscle cells, potentially informing therapeutic approaches for respiratory diseases.
