BIOS 255 Week 7 Respiratory System Physiology Lab Report (2023/2024)

BIOS 255 Week 7 Respiratory System Physiology Lab Report (2023/2024). Respiratory Physiology Lab Report 1. Purpose: The purpose of this lab is to understand the structures and physiology of the respiratory system. 2. Procedure: Read and complete the interactive sections on Anatomy.TV. 3. Data and Details: a. Complete the table regarding partial pressures of oxygen (PO2) and carbon dioxide (PCO2) (mm Hg): Partial pressure in atmospheric air Partial pressure in alveoli Partial pressure in pulmonary capillaries Partial Pressure in systemic capillaries Partial Pressure in tissues Oxygen Carbon dioxide X (not provided) b. Define external and internal respiration. External respiration is the exchange of oxygen and carbon dioxide with the environment in the lungs while internal respiration is the exchange of oxygen and carbon dioxide between capillaries and tissues in the body. c. Identify the cell of the respiratory membrane that secretes surfactant. Surfactant is released by type 2 alveolar cells on the alveolar cell wall. d. State Henry’s law regarding gases. Henry’s law states that the amount of gas which can dissolve in a solution is proportional to both solubility and partial pressure.
