Anatomy of the Lung

Respiratory rate is a vital sign but is often not recorded. This article, the second in a five-part series , explains the anatomy and physiology of breathing and how it is affected by ill health. Measurement of respiratory rate is a vital sign. Nurses need to understand the anatomy and physiology of normal breathing to measure respiratory rate and interpret findings. The second in our five-part series on respiratory rate describes the process of breathing and how it is affected by ill health.

A major organ of the respiratory system, each lung houses structures of both the conducting and respiratory zones. The main function of the lungs is to perform the exchange of oxygen and carbon dioxide with air from the atmosphere. To this end, the lungs exchange respiratory gases across a very large epithelial surface area—about 70 square meters—that is highly permeable to gases. The lungs are pyramid-shaped, paired organs that are connected to the trachea by the right and left bronchi; on the inferior surface, the lungs are bordered by the diaphragm. The diaphragm is the flat, dome-shaped muscle located at the base of the lungs and thoracic cavity.

Applied Respiratory Physiology

Disorders of the Respiratory Tract pp Cite as. The anatomy and physiology of the respiratory tract is quite complex. Each anatomic segment performs in concert with the others and is accountable for a wide variety of physiological responsibilities. These responsibilities vary with rest or exercise, disease or health. Throughout this book, the reader will discover that the respiratory tract is a delicate and complicated system that can be involved in a number of disease processes.

22.2 The Lungs

The lungs are the major organs of the respiratory system , and are divided into sections, or lobes. The right lung has three lobes and is slightly larger than the left lung, which has two lobes. The lungs are separated by the mediastinum. This area contains the heart , trachea , esophagus , and many lymph nodes. The lungs are covered by a protective membrane known as the pleura and are separated from the abdominal cavity by the muscular diaphragm.

Clinical application of anatomical and physiological knowledge of respiratory system improves patient's safety during anaesthesia. It also optimises patient's ventilatory condition and airway patency. Such knowledge has influence on airway management, lung isolation during anaesthesia, management of cases with respiratory disorders, respiratory endoluminal procedures and optimising ventilator strategies in the perioperative period. Understanding of ventilation, perfusion and their relation with each other is important for understanding respiratory physiology.

Applied Respiratory Physiology, Third Edition focuses on the applications of respiratory physiology and is designed to bridge the gap between applied respiratory physiology and the treatment of patients. This book is divided into two parts; the first of which is confined to general principles and the second deals with the various applied situations. This text is comprised of 29 chapters. After giving a general introduction to human respiratory physiology, including the functional anatomy of the respiratory tract, this book turns to the topic of the elastic resistance afforded by lungs and chest wall, along with its effect on the resting end-expiratory lung volume or functional residual capacity. The role of anesthesia in the control of breathing and the relative distribution of ventilation and perfusion are then examined.

Там тоже были группы из четырех знаков. - Потрясающе, - страдальчески сказал директор.  - У вас, часом, нет такой же под рукой. - Не в этом дело! - воскликнула Сьюзан, внезапно оживившись.

 - Она застонала. Все четко, ясно и. Танкадо зашифровал Цифровую крепость, и только ему известен ключ, способный ее открыть. Но Сьюзан трудно было представить себе, что где-то - например, на клочке бумаги, лежащем в кармане Танкадо, - записан ключ из шестидесяти четырех знаков, который навсегда положит конец сбору разведывательной информации в Соединенных Штатах. Ей стало плохо, когда она представила себе подобное развитие событий.

 - Она не дала ему договорить. Бринкерхофф почти физически ощущал, как интенсивно работают клеточки ее мозга. - Помнишь, что случилось в прошлом году, когда Стратмор занимался антисемитской террористической группой в Калифорнии? - напомнила .

    The trillions of cells in the body require an abundant and continuous supply of oxygen to carry out their vital functions.
