Functionally, the respiratory system is separated into a conducting zone and respiratory zone. The conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles.These structures form a continuous passageway for air to move in and out of the lungs. The respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli.These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).he lower tract structures are found in the thorax or chest and include the trachea, bronchi, and lungs (= bronchioles, alveolar ducts, and alveoli). * Please note that many authorities include the larynx with the lower respiratory tract structures.
The only Beatles album to occasion negative, even hostile reviews, there are few other rock records as controversial as Let It Be. First off, several facts need to be explained: although released in May 1970, this was not their final album, but largely recorded in early 1969, way before Abbey Road.
Oh Look Out! On July 22, 1963, Vee Jay Records released what was the first Beatles' album in America. It was released in two versions; the monaural (#VJLP1062) and in stereo (#SR1062), and is today one of the most valuable of all The Beatles' albums, and one of the most counterfeited.
