The trillions of cells in the body require an abundant and continuous supply of oxygen to carry out their vital functions. The organs of the respiratory system include the nose, pharynx, larynx, trachea, bronchi, and their smaller branches, and the lungs, which contain the alveoli. The larynx or voice box routes air and food into the proper channels and plays a role in speech.
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. An understanding of the anatomy and physiology of the respiratory tract is critical to understanding this elaborate system to maintain respiratory health and treat respiratory diseases.

Anatomy and physiology of respiratory system relevant to anaesthesia
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. Ventilation to perfusion ratio alters with anaesthesia, body position and with one-lung anaesthesia. Hypoxic pulmonary vasoconstriction, an important safety mechanism, is inhibited by majority of the anaesthetic drugs.
Place your hand over your chest, take a deep breath, and then let it out. Of course you already know that your lungs fill with air when you breathe, but did you know that your respiratory system does more than simply move oxygen into and out of your lungs? The structures of the respiratory system interact with structures of the skeletal, circulatory, and muscular systems to help you smell, speak, and move oxygen into your bloodstream and waste out of it.

If you look in the image below, you'll see a treelike structure in each lung.
Anatomy and Physiology: The Relationships of the Respiratory System
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.
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.
22.2 The Lungs
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.
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 respiratory system also respiratory apparatus , ventilatory system is a biological system consisting of specific organs and structures used for gas exchange in animals and plants. The anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history. In land animals the respiratory surface is internalized as linings of the lungs. These microscopic air sacs have a very rich blood supply, thus bringing the air into close contact with the blood. These enter the lungs where they branch into progressively narrower secondary and tertiary bronchi that branch into numerous smaller tubes, the bronchioles.
Комната служила гордым напоминанием о тех временах: доспехи, гравюры на военные сюжеты и золотые слитки из Нового Света за стеклом. За конторкой с надписью КОНСЬЕРЖ сидел вежливый подтянутый мужчина, улыбающийся так приветливо, словно всю жизнь ждал минуты, когда сможет оказать любезность посетителю. - En que puedo servile, senor. Чем могу служить, сеньор? - Он говорил нарочито шепеляво, а глаза его внимательно осматривали лицо и фигуру Беккера. Беккер ответил по-испански: - Мне нужно поговорить с Мануэлем. Загорелое лицо консьержа расплылось еще шире. - Si, si, senor.
