Aging and the respiratory system
Aging Clinical and Experimental Research, 1996All the components of the respiratory system are affected by aging, though at different rates: i) the lung elastic recoil decreases; ii) PaO2 decreases and the D(A-a)O2 increases; iii) the chest wall becomes stiffer; iv) the inspiratory muscles loose strength; and v) the respiratory centres are less sensitive.

Seminars in Respiratory and Critical Care Medicine, 2023
Abstract While static mechanical forces govern resting lung volumes, dynamic forces determine tidal breathing, airflow, and changes in airflow and lung volume during normal and abnormal breathing. This section will examine the mechanisms, measurement methodology, and interpretation of the dynamic changes in airflow and lung volume ...

Helminths and the Respiratory System
Archivos de Bronconeumología ((English Edition)), 20061998. We will begin with a brief overview of the main genera and species involved, followed by a description of the point in the life cycle of each parasite when contact with the respiratory apparatus takes place. The second part of the article is a review of the principal epidemiological characteristics, with particular emphasis on the geographical ...

Endothelin and the respiratory system
Trends in Pharmacological Sciences, 1993Pharmacological research involving the endothelin peptides has emphasized their activities in vascular systems, from both physiological and pathophysiological perspectives. However, the endothelins are known also to be synthesized and released from respiratory epithelial cells and to have potent effects in nonvascular components of the respiratory ...

Aquaporins in Respiratory System
2023Aquaporins (AQPs) are water channel proteins facilitating fluid transport in alveolar space, airway humidification, pleural fluid absorption, and submucosal gland secretion. In this chapter, we mainly focus on the expression of four AQPs in the lungs, which include AQP1, AQP2, AQP4, and AQP5 in normal and disease status, and the experience of AQPs ...

Pediatric Clinics of North America, 2016
Respiratory system involvement in cystic fibrosis is the leading cause of morbidity and mortality. Defects in the cystic fibrosis transmembrane regulator (CFTR) gene throughout the sinopulmonary tract result in recurrent infections with a variety of organisms including Pseudomonas aeruginosa, methicillin-resistant Staphylococcus aureus, and ...

Scoliosis and the respiratory system
Paediatric Respiratory Reviews, 2006Scoliosis is caused by the lateral displacement and rotation of the vertebral bodies. It is most common during periods of rapid somatic growth. Scoliosis impedes on the movement of the ribs, places the respiratory muscles at a mechanical disadvantage and displaces the various organs of the thoracic cavity.

The Chelonian Respiratory System
Veterinary Clinics of North America: Exotic Animal Practice, 2011This article reviews anatomy, physiology, diagnostic techniques, and specific disease syndromes of the chelonian respiratory system. Respiratory disease is common in chelonians and is a cause of significant morbidity and mortality in these animals. Mycoplasma, herpesvirus, and iridovirus are reviewed in depth.
