Respiratory System Anatomy and Physiology

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.

The major organs of the respiratory system function primarily to provide oxygen to body tissues for cellular respiration, remove the waste product carbon dioxide, and help to maintain acid-base balance. Portions of the respiratory system are also used for non-vital functions, such as sensing odors, speech production, and for straining, such as during childbirth or coughing Figure Functionally, the respiratory system can be divided into a conducting zone and a respiratory zone. The conducting zone of the respiratory system includes the organs and structures not directly involved in gas exchange. The gas exchange occurs in the respiratory zone. The major functions of the conducting zone are to provide a route for incoming and outgoing air, remove debris and pathogens from the incoming air, and warm and humidify the incoming air.

The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide. The respiratory system has many functions. Besides helping you inhale breathe in and exhale breathe out , it:. The respiratory system has many different parts that work together to help you breathe.

Anatomy and Physiology of the Respiratory Tract

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. To do this, at least four distinct events, collectively called respiration, must occur. The most inferior cartilage in the larynx is the epiglottis. Unlike the other cartilages of the larynx, the epiglottis consists of hyaline cartilage.

The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx , larynx , trachea , bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function. The nose, pharynx, larynx, trachea and bronchi all work like a system of pipes through which the air is funnelled down into our lungs. There, in very small air sacs called alveoli, oxygen is brought into the bloodstream and carbon dioxide is pushed from the blood out into the air. When something goes wrong with part of the respiratory system, such as an infection like pneumonia , it makes it harder for us to get the oxygen we need and to get rid of the waste product carbon dioxide. Common respiratory symptoms include breathlessness , cough , and chest pain.


BASIC ANATOMY AND PHYSIOLOGY. • Respiratory System External respiration - movement of oxygen from the lungs to the blood and movement of carbon.

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.

Теперь он был на виду, его голова торчала из оконного проема как на гильотине. Беккер подтянул ноги, стараясь протиснуться в проем.

ГЛАВА 63 Новообретенная веспа Дэвида Беккера преодолевала последние метры до Aeropuerto de Sevilla. Костяшки его пальцев, всю дорогу судорожно сжимавших руль, побелели. Часы показывали два часа с минутами по местному времени. Возле главного здания аэровокзала Беккер въехал на тротуар и соскочил с мотоцикла, когда тот еще двигался. Машина упала на бок и замерла.

 Как же так? - Сьюзан откинулась на спинку стула.  - У нас внизу работают лучшие программисты в мире. И мы нашими совместными усилиями даже близко не подошли к математической функции меняющегося открытого текста.

Итак, каков следующий шаг. Он решил подумать об этом через минуту. Сейчас ему надо было совершить давно уже откладываемую прогулку в туалетную комнату. ГЛАВА 64 Сьюзан осталась одна в тишине и сумерках Третьего узла. Стоявшая перед ней задача была проста: войти в компьютер Хейла, найти ключ и уничтожить все следы его переписки с Танкадо.

На такой риск вы не пойдете. Сьюзан было запротестовала, но Стратмор не дал ей говорить. - Вы меня не знаете, молодой человек.

К тому же Сьюзан написала свой маячок на новом гибридном языке, именуемом LIMBO, поэтому не приходилось удивляться, что Стратмор с ним не справился. - Я возьму это на себя, - улыбнулась она, вставая.  - Буду у своего терминала. - Как ты думаешь, сколько времени это займет.

Деревянные скамьи заполняют вертикальную ось, растянувшись на сто с лишним метров, отделяющих алтарь от основания креста. Слева и справа от алтаря в поперечном нефе расположены исповедальни, священные надгробия и дополнительные места для прихожан. Беккер оказался в центре длинной скамьи в задней части собора.
