inspiration is an active process that takes place by creation of negative intrathoracic pressure, in normal states where breathing is vesicular, even at a low negative pressure air keep on flowing into alveoli but in bronchial breathing as alveoli are either filled with secretions as in consolidation or a cavity is already filled with air and other contents, no movement of air takes place at the end inspiration despite of negative intrathoracic pressure thereby causing a pause between inspiration and expiration- now pay me thousand dollar!
The interval between expiration (breathing out) and inspiration (breathing in) is called the respiratory cycle. During this cycle, the lungs expand and contract to allow air to move in and out of the body.
Among the definitions of both words, inspiration and expiration are similar in the act of breathing. Humans breathe in (inspires) and breathes out (expires).

The pontine respiratory group within the pons plays a key role in coordinating smooth transitions between inspiration and expiration by controlling the respiratory cycle. It includes both the inspiratory center, which helps initiate inspiration, and the expiratory center, which regulates the rate and depth of expiration. Together, these regions help maintain a coordinated and rhythmic breathing pattern.
Breathing is the process of taking air into and out of the lungs, while ventilation refers to the movement of air in and out of the lungs to facilitate gas exchange. Ventilation involves both breathing (inspiration and expiration) and the distribution of air within the lungs.
The main difference between the muscles involved in inspiration and expiration is that inspiration involves the diaphragm and external intercostal muscles, which contract to expand the chest cavity and draw air into the lungs. In contrast, expiration primarily involves the relaxation of these muscles, along with the internal intercostal muscles and abdominal muscles, which contract to compress the chest cavity and push air out of the lungs.
Expired means past use or dead. Inspired (inspire) means to be enlivened or filled with exalting emotion.
The diaphragm, a sheet of muscles spanning the rib cage just below the lungs, is mainly responsible for both inspiration and expiration. The intercostal muscles are also used, expanding and contracting the the space between the ribs. The abdominal muscles are used to a lesser extent either by relaxing to allow further expansion of the diaphragm or contraction for rapid expulsion of air. (Note to the person who answered this question previously: "Inspiration" means to inhale. "Expiration means to exhale. Don't tell someone that they don't know what they are talking about unless you know what you are talking about.)
Bronchovesicular breath sounds are best heard over major airways, specifically in the areas of the anterior chest around the sternal border and between the scapulae on the posterior chest. These sounds occur in the central regions of the lung, where the bronchial and vesicular sounds converge. They are typically heard during both inspiration and expiration and are considered normal in these areas.
Inspiration happens when the pressure inside the lungs is lower than the atmospheric pressure (outside) and air rushes into the lungs. Expiration is when the air inside the lungs is higher than the atmospheric pressure and the air rushes out of the lungs. If the intrapleural pressure (pressure within the pleura of the lungs) isn't maintained then the pressure in the lungs can't differentiate between inspiration and expiration and so the lung collapses.
The "Trachea".
The tube that connects the throat and the bronchial tube is the esophagus.The tube that connects to the bronchial tubes is actually the trachea:9. What tube connects to the bronchial tubes? Trachea CORRECThttp://library.thinkquest.org/15401/cgi-bin/resp_quiz.cgi
