The respiratory testing in Cleveland Ohio is an organ system which is used for gas exchange. Among four-legged animals, the respiratory testing in Cleveland Ohio system generally includes tubes, such as the bronchi, used to carry air to the lungs, where gas exchange takes place. A diaphragm pulls air in and pushes it out. Respiratory testing in Cleveland Ohio systems of various types are found in a wide variety of organisms. Even trees have respiratory testing systems.

In humans and other mammals, the respiratory testing in Cleveland Ohio system consists of the airways, the lungs, and the respiratory testing in Cleveland Ohio muscles that mediate the movement of air into and out of the body. Within the alveolar system of the lungs, molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous environment and the blood. Thus, the respiratory testing in Cleveland Ohio system facilitates oxygenation of the blood with a concomitant removal of carbon dioxide and other gaseous metabolic wastes from the circulation. The system also helps to maintain the acid-base balance of the body through the efficient removal of carbon dioxide from blood.

The respiratory testing in Cleveland Ohio system can be conveniently subdivided into an upper respiratory tract and lower respiratory tract, trachea and lungs. These sections are also called the conducting zone and a respiratory testing in Cleveland Ohio zone.

The conducting zone starts with the nares (nostrils) of the nose, which open into the nasopharynx (nasal cavity). The primary functions of the nasal passages are to: 1) filter, 2) warm, 3) moisten, and 4) provide resonance in speech. The nasopharnyx opens into the oropharynx (behind the oral cavity). The oropharynx leads to the laryngopharynx, and empties into the larynx (voicebox), which contains the vocal cords, passing through the glottis, connecting to the trachea (wind pipe) which leads down to the thoracic cavity (chest) where it divides into the right and left "main stem" bronchi. The subdivision of the bronchus are: primary, secondary, and tertiary divisions (first, second and third levels). In all, there are up to 16 more times into even smaller bronchioles.

The bronchioles lead to the respiratory testing in Cleveland Ohio zone of the lungs which consists of respiratory bronchioles, alveolar ducts and the alveoli, the multi-lobulated sacs in which most of the gas exchange occurs.

Ventilation of the lungs is carried out by the muscles of respiration. Inhalation is initiated by the diaphragm and supported by the external intercostal muscles. Normal resting respirations are 10 to 18 breaths per minute. During vigorous inhalation (at rates exceeding 35 breaths per minute), or in approaching respiratory testing failure, accessory muscles of respiration are recruited for support. These consist of sternocleidomastoid, platysma, and the strap muscles of the neck. Exhalation is generally a passive process, however active or forced exhalation is achieved by the abdominal and the internal intercostal muscles.

Ventilation occurs under the control of the autonomic nervous system from the part of the brain stem, the medulla oblongata and the pons. This area of the brain forms the respiration regulatory center, a series of interconnected nerons within the lower and middle brain stem which coordinate respiratory testing in Cleveland Ohio movements. The sections are the pneumotaxic center, the apneustic center, and the dorsal and ventral respiratory testing in Cleveland Ohio groups. This section is especially sensative during infancy, and the neurons can be destroyed if the infant is dropped or shaken violently. The result can be death due to "shaken baby syndrome."

The respiratory testing in Cleveland Ohio system lies dormant in the human fetus during pregnancy. At birth, the respiratory testing in Cleveland Ohio system is drained of fluid and cleaned to assure proper functioning of the system. If an infant is born before forty weeks gestational age, the newborn may expereince respiratory failure due to the under-developed lungs. This is due to the incomplete development of the alveoli type II cells in the lungs. The infant lungs do not function due to the collapse of the alveoli caused by surface tension of water remaining in the lungs. Surfactant is lacking from the lungs, leading to the condition. This condition may be avoided if the mother is given a series of steriod shots in the final week prior to delivery. The steriods accelerate the development of the type II cells.

The major function of the respiratory testing in Cleveland Ohio system is gas exchange. Respiration consists of a mechanical cycle of inhalation and exhalation, with gaseous exchange occurring in between. As gas exchange occurs, the acid-base balance of the body is maintained as part of homeostasis. If proper ventilation is not maintained two opposing conditions could occur: 1) respiratory acidosis, a life threatening condition, and 2) respiratory alkalosis.

Inhalation is driven primarily by the diaphragm. When the diaphragm contracts, the ribcage expands and the contents of the abdomen are moved downward. This results in a larger thoracic volume, which in turn causes a decrease in intrathoracic pressure. As the pressure in the chest falls, air moves into the conducting zone. Here, the air is filtered, warmed, and humidified as it flows to the lungs.

In an average resting adult, the lungs take up about 250ml of oxygen every minute while excreting about 200ml of carbon dioxide. During an average breath, an adult will exchange from 500 ml to 700 ml of air. This average breath capacity is called tidal volume. The movement of gas through the larynx, pharynx and mouth allows us to speak, or phonate.

The respiratory testing in Cleveland Ohio tract is constantly exposed to microbes due to the extensive surface area, which is why the respiratory testing in Cleveland Ohio system includes many mechanisms to defend itself and prevent pathogens from entering the body.

A respiratory testing in Cleveland Ohio system´s function is to allow gas exchange. The space between the alveoli and the capillaries, the anatomy or structure of the exchange system, and the precise physiological uses of the exchanged gases vary depending on the organism. In humans and other mammals, for example, the anatomical features of the respiratory testing in Cleveland Ohio system include airways, lungs, and the respiratory muscles. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood. This exchange process occurs in the alveolar region of the lungs.
