Summary Introduction

To determine: The effect of decreasing the blood flow due to lung tumor on Po₂ (partial pressure) of oxygen and Pco₂ (partial pressure of carbon dioxide) in the alveoli and interstitial fluid.

Introduction: Alveoli are the smallest sac-like structure present in the lungs. The exchange of gases takes place in alveoli. The pressure developed in alveoli by the gaseous exchange is called alveolar pressure.

Summary Introduction

To determine: The response of bronchioles to th lung tumor and whether the response of bronchioles can generate ventilation in the lungs.

Introduction: The air enters the nose during inhalation. After that, air moves to the nasal passage, pharynx, larynx, tracheas, bronchi, and bronchioles. After passing the bronchioles, the air enters the alveoli. The gaseous exchange takes place at alveoli
