These movements are essential for the exchange of oxygen and carbon dioxide in the lungs. Inhalation brings fresh air into the respiratory system, while exhalation expels carbon dioxide. Pleura: The pleura consists of two layers – parietal pleura and visceral pleura – surrounding the lungs. The...
Breathing 01 – respiratory system JennyXu 边学习边寻找发展方向,希望能记录突破的轨迹 The body can survive without food or water for some time, but soon dies if breathing stops. Breathing brings fresh air containing oxygen into the lungs, and then expels stale air containing waste carbon dioxide...
通常称鼻、咽、喉为上呼吸道,气管和各级支气管为下呼吸道。肺是由肺实质及肺间质组成,是气体交换的器官。 The respiratory system consists of respiratory tract and lungs. The nose, pharynx and throat are usually called the upper respiratory tra...
The human respiratory system, working in conjunction with the circulatory system, supplies oxygen to the body's cells, removing carbon dioxide in the process. The exchange of these gases occurs across cell membranes both in the lungs (external respiration) and in the body tissues (internal ...
A sample of sputum is placed in a sterile container and sent to the laboratory for testing. Sputum may be expectorated (produced by coughing), induced (saline is sprayed in the lungs to induce sputum production), or taken via an endotracheal tube (commonly used on patients on respirators) ...
Throughthe process of breathin end, airreach in oxygen is called inhalation. After the contraction of the muscular diaphragm, the lungs expand, and the air rushes in, resulting in the inflation of the alveoli,. During exhalation the diaphragm moves up in the lungs contract. Thus the alveoli ...
The structures of the lower respiratory system include the trachea, through the lungs and diaphragm. These structures are responsible for gas exchange and external respiration.

The respiratory system supplies the blood with vital oxygen for all the body's organs. We breathe in when a sheet of muscles across the bottom of the chest cavity (the diaphragm) contracts, pulling air into the lungs, and we breathe out when the diaphragm relaxes. Air enters through the ...
Human respiratory system, the system in humans that takes up oxygen and expels carbon dioxide. The major organs of the respiratory system include the nose, pharynx, larynx, trachea, bronchi, lungs, and diaphragm. Learn about the anatomy and function of t
