This occurs within the respiratory system. During inpiration, the intercostal muscles contract, the diaphragm descends, and the rib cage rises. The thoracic cavity volume increases, stretching the lungs, and the intrapulmonary volume increases. This causes the intrapulmonary pressure to drop. Air flows into the lungs until the intrapulmonary pressure equals the atmospheric pressure. During expiration the intercostal muscles relax, the diaphragm rises, and the rib cage descends. The thoracic cavity volume decreases, causing the the lungs to recoil, and the intrapulmonary volume decreases. This causes the intrapulmonary pressure to rise, and the air flows out of the lungs until the intrapulmonary pressure equals the atmospheric pressure.
What else can I help you with?
What signalled the end of inspiration and the beginning of expiration?
The end of inspiration is signalled by the relaxation of the diaphragm and the external intercostal muscles. This causes the lungs to passively recoil, leading to expiration.
What is different between inspiration and expiration?
Expired means past use or dead. Inspired (inspire) means to be enlivened or filled with exalting emotion.
Does the duration of inspiration or expiration vary during ERV or FVC?
Yes, the duration of inspiration or expiration can vary during forced vital capacity (FVC) and expiratory reserve volume (ERV) maneuvers. This variation is influenced by individual factors such as lung capacity, respiratory muscle strength, and airway resistance. In general, inspiration tends to take longer during FVC, while expiration tends to take longer during ERV.
What is inhale and exhale is known as?
Inhale is known as inspiration, while exhale is known as expiration. These terms are commonly used in the context of breathing and refer to the process of taking in and releasing air from the lungs, respectively.
What happens during inspiration and expiration?
During inspiration, the diaphragm and intercostal muscles contract, expanding the chest cavity and allowing air to rush into the lungs. During expiration, the diaphragm and intercostal muscles relax, causing the chest cavity to decrease in size and air to be pushed out of the lungs.
What is the difference between normal inspiration and expiration and forced inspiration and expiration?

Inspiration not equal to expiration?
Inspiration should equal to expiration;IE ratio and IT , inspiration equals tidal volume. It means that the patient is having trouble breathing.
Does emphysema make inspiration or expiration more difficult?
Yes, in asthma, bronchitis, emphysema expiration is difficult than inspiration..
What is the interval between expiration and inspiration?
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.
Period of breathing when air leaves the lungs?
Inspiration.
Two phases of ventilation?
inspiration and expiration.
What are the processes involved in respiration?
Inspiration and Expiration
What is the similarity between inspiration and expiration?
Among the definitions of both words, inspiration and expiration are similar in the act of breathing. Humans breathe in (inspires) and breathes out (expires).
What signalled the end of inspiration and the beginning of expiration?
The end of inspiration is signalled by the relaxation of the diaphragm and the external intercostal muscles. This causes the lungs to passively recoil, leading to expiration.
How many parts to pulmonary ventilation and what are they?
There are two parts. Inhalation and exhalation also known as inspiration and expiration. Inspiration is the process of breathing air into the lungs it helps in oxygenation. Expiration is breathing out and it does not require any specific muscle activity. Expiration occurs due to elastic recoiling of the lungs after inspiration
What does a single respiration consist of?
It's mad of inspiration and expiration
What is Quiet inspiration and what is quiet expiration?
Quiet inspiration is likely just breathing in at rest. Quiet expiration is likely just breathing out at rest when you are not out of breath or undergoing any physical activity
