Question

how we will appreciate the roll of diaphgram in respiratory movements​

Answer 1

Answer:

➝ The diaphragm is the membranous structure in the abdomen.

➝This structure becomes flat during inspiration which helps to increase the volume of the thoracic cage. This allows the air to be taken in the lungs.

➝During the process of expiration, the diaphragm becomes dome-shaped. This reduces the volume of the thoracic cage and helps to pump the CO2 out from the lungs.

Answer 2

Role of diaphragm in respiratory movement.

Explanation:

• Diaphragm is located below the lungs.
• It is the major muscle for respiration.
• It is dome shaped  muscle that contracts rhythmically and continually and involuntarily.
• During inhalation it contracts and flattens, the chest cavity enlarges.
• This creates a vaccum which pulls air into the lungs , because of the negative pressure inside the lungs.
• Which pulls the air into the lungs.
• While exhalation it relaxes and returns to its original position as a result , the air is forced out of the lungs.
