Terms of respiration
What is ventilation?
Breathing in and out, moving air to and from the lungs
What is the diaphragm?
It is a primary muscle that separates the thorax and abdomen and helps with breathing.
What is respiration?
It is the exchanges of gasses within the lungs
What are the internal intercostal muscles responsible for?
During forced expiration, it depresses (lower) the ribs, decreasing the thoracic cavity and pushing air out of the lungs. They are important for controlled expiration in speech.
What is speech breathing and how is it influenced?
It is 10% inhalation and 90% exhalation, it is an adaptation for a means to communicate. The longer exhalation allows for control to power speech. Speech breathing can be influence by body positions because gravity can affect the relaxation pressure, resting level and the mechanical advantages of the chest wall.
What are the alveoli?
It is located in the lower respiratory tract, they are small sacs of air and this is where oxygen and carbon dioxide exchange.
What is decreased intrapulmonary pressure?
It is when there is a drop in air pressure within the lungs. In essence this pressure change allows for air to flow into the lungs, INHALATION.
What is intercostal and abdominal muscles and their function?
There are external, internal, and innermost intercostal muscles.
The abdominal muscles consist of the rectus abdominis, transverse abdominis, and obliques.
These muscles work together to control expiration by stabilizing the rib cage and regulating lung volume.
