Gas exchange surfaces - Study guides, Revision notes & Summaries

PATHO 370 MIDTERM EXAM LATEST COMPLETE GUIDE 2023. PATHO 370 Pathophysiology. Gas exchange occurs in which of the respiratory system's structures? Selected Answer: Trache a Correct Answer: Alveoli Response Feedback: The alveoli allow air to come in indirect contact with the bloodstream through the pulmonary capillary system. This alveolar membrane, which is one cell thick, allows carbon dioxide to diffuse into the alveoli from the bloodstream and oxygen to diffuse to the bloodstream ...

EXCHANGE SURFACES VERIFIED SOLUTIONS 2023/2024 Why do multicellular organisms need specialised exchange surfaces but single celled organisms don't? - ANSWER single celled organisms can exchange materials across their CSM to meet requirements - metabolic activity low → O2 needs low + CO2 produced is low - large SA:V ratio Multicellular organisms are the opposite - high metabolic rate (active + maintain temp) - small SA:V ratio 3 main features of an efficient exchange surface - ...

GMS 6402 Pulmonary Physiology Questions And Answers Well Illustrated. Epiglottis - correct answer. Covers local cords and trachea during swallowing Prevents movement of air into the lungs Food and water to esophagus Air to trachea Lung Anatomy - correct answer. Right lung: 3 lobes Left lung: 2 lobes Left has oblique fissure Right has oblique fissure and Horizontal fissure Cardiac notch is anatomical hallmark for position of left ventricle All cardiac output travels ...

Explain the anatomical components of the respiratory system. > respiratory zone muscles - major muscle = diaphragm *controlled by the phrenic nerve (C3-C5 of the neck), so any pt w an injury to the spine/phrenic nerve will require ventilatory support! - accessory muscles = intercostals, abdominals, trapezius, sternocleidomastoid To move air into the lungs...respiratory muscles generate negative intrapleural pressure = allows air inflowing via the pressure gradient btwn atmospheric pressure at...
