Answer: Inspiration is the active phase of breathing. During this time, the diaphragm and the intercostals muscles contract, intrapleural pressure decreases even more, the lungs expand, and air rushes in. Expiration is normally passive—that is, the diaphragm and external intercostals muscles are ...
Pulmonary ventilation, the medical term for breathing, happens when air flows into the lungs during inspiration (inhalation) and out of the lungs during expiration (exhalation). This natural and essential process takes no thought and usually very little effort. But, breathing is much more complex ...
The processes of inspiration (breathing in) and expiration (breathing out) are vital for providing oxygen to tissues and removing carbon dioxide from the body. Inspiration occurs via active contraction of muscles – such as the diaphragm –whereas expiration tends to be passive, unless it is force...
The Mechanics of Breathing:Breathing, or pulmonary ventilation, is the result of muscular contractions and relaxations that change the volume and pressure of the thoracic cavity. Inhalation is an active process, one which requires the contraction of muscles. The diaphragm contracts downw...
During exhalation, as the muscles relax, all of the actions associated with inhalation are reversed, and the dimensions of the chest space reduce. Normal, quiet breathing is an involuntary process, in that a person does not have to think about it for it to happen. Sometimes, what is known...
What is normal, quiet breathing called?HyperventilationUnder certain conditions of stress, hyperventilation may take place in the case of some individuals. This is because in the presence of stress the oxygen requirement in the body rises in a steady manner. To balance the required level of ...

When a person breathes out normally, then the amount of air which remains in the lung after a normal expiration is View Solution Assertion:−The volume of air a person can expire after normal inspiration is TV=ERV Reason:−Volume of air that will remain in the lungs after a normal exp...
What is inspiration and expiration in the respiratory system? What is the function of the pulmonary circuit? How do the lungs and heart transport oxygen in the cardiorespiratory system? What are autonomic functions? How does the respiratory system interact with the integumentary system?
