Nursing Times 113: 3, 53-55.Īuthors: John Knight is senior lecturer in biomedical science Yamni Nigam is associate professor in biomedical science both at the College of Human Health and Science, Swansea University. The 70 time of the stabilization reaction can be estimated, it is 20 sec. Pre-Lab Carefully read the introductory material and examine the entire lab. 6 Apply concepts covered in this laboratory exercise to the changes that occur when the bronchioles are dilated or constricted by the autonomic nervous system. This second article in our updated series on age-related changes in the main organ systems looks at the respiratory system.Ĭitation:Â Knight J, Nigam Y (2017) Anatomy and physiology of ageing 2: the respiratory system. 5 Explain the changes in tidal volume in response to changes in volume of the anatomic dead space. Like all organ systems, it becomes less efficient with age. The respiratory system has a key role in gaseous exchange but also helps to regulate blood pH, control blood pressure and provide non-specific immune defence mechanisms.

Make sure to describe what causes the drop in PO2 at each point. The normal ageing process brings about changes to the respiratory system which mean older people are at increased risk of respiratory tract infections. Kaori777 Christian Stricker Tuesday, Septem2pm Terms in this set (24) Describe the changes in PO2 that occur along the respiratory tract and blood.

If the bronchioles are dilated the anatomic dead space and tidal volume will
