The respiratory system performs gas exchange. lungs make air to move to alveolar for the gas exchange process. Mechanism of gas entering in the lung where gas molecules make force on the surface. Gas present in the different type of molecules. partial pressure is a single type of gas in gas mixture important for the movement of gases. gas move from an area where the partial pressure is high or low. in that place more rapid movement of gas will happen. the concentration of gas in a liquid depends upon the solubility of a gas in the liquid. Equilibrium of gas molecules dissolved in air and liquid. The air in the alveoli and in the atmosphere composition differs. Gas exchange removes o2 and co2 to alveolar air. when there is deep and forces breath that changes the alveolar air composition more rapidly than normal breathing. that time partial pressure o2 and co2 changes that affect the diffusion process that makes movement pf materials across the membrane. this process cause o2 to enter and co2 to leave the blood rapidly.
Diffusing capacity is measured for how well o2 and co2 are diffused between lung and blood. incase of lung disease pulmonary function level decrease the diffusion capacity reduces according to the severity due to restrictive and obstructive lung disease. pulmonary artery occlusion and conditions like respiratory distress cause hypoxia and hypocapnia that reduce the co2 elimination and cause alveolar co2 tension that causes alveolar collapse and induced bronchoconstriction. pulmonary gas exchange abnormal, ischemia, inflammation, reperfusion condition cause alteration in lung mechanism, it alters the vital signs like bradypnea and tachypnea, tachycardia due to the hypoxic condition due to airway obstruction.

Explain how we measure economic growth and discuss three specific things that government could do to improve economic growth in the long run. Our current unemployment rate is 3.6% in the United States. Explain as clearly as possible what that 3.6% means (where does that number come from?) Then explain how that compares to our goal for unemployment.
