Explain the inspiration phase of abdominal breathing!
Answers
The process of breathing (respiration) is divided into two distinct phases, inspiration (inhalation) and expiration (exhalation). During inspiration, the diaphragm contracts and pulls downward while the muscles between the ribs contract and pull upward. ... As a result, the lungs contract and air is forced out.
The inspiration phase in abdominal breathing occurs when the diaphragm muscles contract or tighten. As a result, the volume of the chest cavity will enlarge, the pressure decreases and air from outside will enter the lungs
Discussion:
Humans can breathe using chest breathing and abdominal breathing.
Chest breathing is breathing that involves the muscles between the ribs. The chest breathing mechanism is as follows:
1. Inspiring phase (breathing air):
In this phase the external muscles in the part between the ribs contract or tighten. As a result, the ribs will rise upward and the volume of the chest cavity will increase. Pressure on the air occurs in the chest cavity so that it shrinks. This makes the air that comes from outside into the lungs.
2. Expiration phase (exhaling):
In this phase the muscles in the part between the ribs experience relaxation or relax. As a result, the rib cage decreases and the volume in the chest cavity decreases. Enlarged air pressure in the chest cavity.
This makes air in the parts of the lungs then out of the body part.
Conversely, abdominal breathing is breathing that involves the diaphragm muscles located between the chest and abdomen.
The mechanism is as follows:
1. Inspiring phase (breathing air):
In this phase the diaphragm muscles contract or tighten. As a result, the diaphragm will be flat and the volume of the chest cavity will increase. Pressure on the air occurs in the chest cavity so that it shrinks. This makes the air that comes from outside into the lungs.
2. Expiration phase (exhaling):
In this phase the diaphragm muscle relaxes or relaxes. As a result, the diaphragm will return to all forms (curved) and the volume in the chest cavity is reduced. Enlarged air pressure in the chest cavity.
This makes air in the parts of the lungs then out of the body part.
