pressure in the lungs forces air to leave the site of gaseous exchange and the diaphragm pushes up forcing the person to exhale.
Exhalation as in breathing out normally is part of your respiratory tidal volume - the volume you use normally, whereas forced exhalation is breathing out more than you need to, your expiratory residual volume.
During inhalation, the diaphragm contracts and moves downwards, causing the chest cavity to expand and draw air into the lungs. During exhalation, the diaphragm relaxes and moves upwards, allowing the chest cavity to decrease in size and push air out of the lungs. These movements ensure proper ventilation of the lungs.
False. When nerve impulses pass to the diaphragm, it contracts, which expands the chest cavity and allows air to enter the lungs (inhalation). The diaphragm relaxes during exhalation, allowing air to be pushed out of the lungs.
Exhalation, or 'breathing out', is the part of breathing where air is released from the lungs. Put another way, it is the end of the cycle of breathing. It is the opposite of inhalation, or 'breathing in', where air is taken into the lungs. OR ANOTHER WAY TO PUT IT... It is when you breathe out. That's why someone might tell you "Inhale..... Exhale.....". It's when the diaphragm pushes the air out of your lungs. When the diaphragm pulls down, you are inhaling. When your diaphragm pushes out, you have just exhaled. That's where the part "exhalation" comes from, and for "human"... I'm pretty sure you'd know that. ;) Hope this helps!
The diaphragm contracts during inhalation, allowing the lungs to expand and fill with air. This helps to create negative pressure in the chest cavity, drawing air into the lungs. During exhalation, the diaphragm relaxes and moves back up, helping to push air out of the lungs.
Exhalation
The air that may be exhaled above the normal volume in a forced exhalation is called "reserve volume" or "expiratory reserve volume." This is the additional volume of air that can be forcibly exhaled after a normal tidal volume exhalation.
There are two phases in one breath: inhalation and exhalation. During inhalation, air is drawn into the lungs, and during exhalation, air is expelled from the lungs.
The diaphragm relaxes during EXHALATION. Your diaphragm flattens when you inhale, creating more space for the lungs to take in more air.

Exhalation as in breathing out normally is part of your respiratory tidal volume - the volume you use normally, whereas forced exhalation is breathing out more than you need to, your expiratory residual volume.
Exhalation is a passive action that results from elastic recoil and changes in air pressure. When this happens naturally a portion of air remains within the lungs- residual volume. However when exhalation is forced, that is conscious efforts to expel as much air as possible, many of the residual volume can be forced out of the lungs.
The act of exhalation itself is caused by the diaphragm relaxing and pushing upward on the lungs, forcing air out of them. This air is loaded with carbon dioxide, a dangerous waste product, so that is eliminated.
The ribs expand during inhalation. This creates negative pressure on the lungs and draws air into them. During exhalation the rib cage gets smaller, compressing the lungs, in a sense, and forcing air out.
Both inhalation and exhalation are part of the respiratory process where air is exchanged in the lungs. During inhalation, the diaphragm and intercostal muscles contract to expand the chest cavity, allowing air to enter the lungs. During exhalation, these muscles relax, and the chest cavity decreases in size, forcing air out of the lungs. The key difference is the direction of airflow: inhalation is the process of taking air into the lungs, while exhalation is the process of expelling air from the lungs.
During inhalation, the diaphragm contracts and moves downwards, causing the chest cavity to expand and draw air into the lungs. During exhalation, the diaphragm relaxes and moves upwards, allowing the chest cavity to decrease in size and push air out of the lungs. These movements ensure proper ventilation of the lungs.
Vocal cords vibrate with expired air when producing sound during exhalation.
