Are inhalation and inspiration the same?
No, inhalation refers to the act of breathing in air or a substance into the lungs, while inspiration is the process of taking in oxygen from the air into the body's cells. Inhalation is a physical action, while inspiration can also refer to motivation or creative influence.
What happens to lung volume during inspiration?
During inspiration, lung volume increases as the diaphragm and external intercostal muscles contract, causing the chest cavity to expand. This expansion creates a pressure gradient that allows air to flow into the lungs, filling them with oxygen.
Does the diaphragm deal with inspiration or expiration?
The diaphragm primarily deals with inspiration. When the diaphragm contracts and moves downward, it creates more space in the chest cavity, allowing air to flow into the lungs. During expiration, the diaphragm relaxes and moves upward passively as the air is forced out of the lungs.
What science word is used for breathing out?
Exhalation.
Carbon dioxide and water are excreted here during exhalation?
The lungs are responsible for excreting carbon dioxide and water during exhalation. Inhaled oxygen is absorbed into the bloodstream, while carbon dioxide, a waste product of cellular respiration, is removed from the body by exhaling it out. Water vapor is also released during exhalation as a byproduct of respiration.
