Normal breathing is called ____A____ breathing whereas forceful breathing is called ____B____ breathing. Choose the option that correctly fills the blanks.
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) - A- Abdominal, B-Thoracic
Normal breathing is called abdominal breathing because it is mainly due to the movement of diaphragm and chest movements are inconspicuous whereas forceful breathing is called thoracic breathing because it involves conspicuous movement of thorax.
Thoracic breathing: It is a type of breathing that involves the chest. The external intercostal muscles are primarily used . This type of breathing usually occurs during vigorous exercise or in emergency situations.
Diaphragmatic or abdominal breathing : represents the typical breathing pattern at rest, characterized by the protrusion of the abdomen as the diaphragm descends. Achieved by contracting the diaphragm, a horizontal muscle situated between the chest and stomach cavities, this breathing method involves the entry of air into the lungs, causing the abdomen to expand. The distinctive feature of this deep breathing style is the enlargement of the abdomen rather than the chest during the inhalation process.
