The respiratory tract is the subdivision of the respiratory system involved with the process of respiration in mammals. Air is breathed in through the nose to the nasal cavity , where a layer of nasal mucosa acts as a filter and traps pollutants and other harmful substances found in the air. Next, air moves into the pharynx , a passage that contains the intersection between the oesophagus and the larynx.

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.

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.

Respiratory system

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. The major function of the respiratory system is to supply the body with oxygen and to dispose of carbon dioxide.

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.

Click Image to Enlarge. Respiration is the act of breathing in and breathing out. When you inhale, you take in oxygen. When you exhale, you give off carbon dioxide.

Anatomy of the Respiratory System in Children

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.

Besides a gravitational perfusion distribution there is also a non-gravitational perfusion inhomogeneity that may possibly exceed gravitational inhomogeneity. The lungs contain 2— million alveoli with a total surface area, for gas exchange, of approximately m 2.


Carbon dioxide is exhaled and oxygen is inhaled through the respiratory system, which includes muscles to move air into and out of the lungs, passageways.

Welcome to the Visible Body Blog!

Он снова с силой пнул ногой педаль стартера. Пуля пролетела мимо в тот миг, когда маленький мотоцикл ожил и рванулся. Беккер изо всех сил цеплялся за жизнь. Мотоцикл, виляя, мчался по газону и, обогнув угол здания, выехал на шоссе. Халохот, кипя от злости, побежал к такси. Несколько мгновений спустя водитель уже лежал на земле, с изумлением глядя, как его машина исчезает в облаке пыли и выхлопных газов.

Стратмор оторвался от перил и переложил пистолет в правую руку. Не произнеся ни слова, он шагнул в темноту, Сьюзан изо всех сил держалась за его плечо. Если она потеряет с ним контакт, ей придется его позвать, и тогда Хейл может их услышать. Удаляясь от таких надежных ступенек, Сьюзан вспомнила, как в детстве играла в салки поздно ночью, и почувствовала себя одинокой и беззащитной, ТРАНСТЕКСТ был единственным островом в открытом черном море. Через каждые несколько шагов Стратмор останавливался, держа пистолет наготове, и прислушивался.

 Я знаю.  - Он улыбнулся.  - Но на этот раз, - он вытянул левую руку так, чтобы она попала в камеру, и показал золотой ободок на безымянном пальце, - на этот раз у меня есть кольцо.

Он. Беккер был уверен, что представляет собой отличную мишень, даже несмотря на то что находился среди огромного множества прихожан: его пиджак цвета хаки ярко выделялся на черном фоне. Вначале он хотел снять его, но белая оксфордская рубашка была бы ничуть ни лучше, поэтому он лишь пригнулся еще ниже.

 Сьюзан. По ее щеке скатилась слеза. - Что с тобой? - в голосе Стратмора слышалась мольба.

Беккер здесь… Я чувствую, что. Он двигался методично, обходя один ряд за другим. Наверху лениво раскачивалась курильница, описывая широкую дугу.
