During Exhalation the Ribs Move

Q. During Exhalation, the ribs move ________

1. up and inwards
2. downward and upward
3. up and outwards
4. down and outward

Answer: downward and upward

Explanation:

Exhalation causes a downward and upward movement of the rib cage, while an upward movement of the diaphragm occurs simultaneously. Because of this movement, the volume of space in our chest cavity increases, and the air is expelled.

Pulmonary Ventilation

The term “breathing” actually refers to the process of pulmonary ventilation. During inspiration (also known as inhalation), this is the process of airflow into the lungs, and during expiration, the air is flowing out of the lungs (exhalation). Pressure changes between the outside air and the gases contained within the lungs cause air to flow through the body.

Exhalation Process

The activity of breathing out, also known as exhalation, is a process that occurs in living organisms.

• During the process of respiration, exhalation is the movement of air from the lungs and out of the airways of the body into the surrounding atmosphere
•  During the exhalation process, the diaphragm is allowed to relax and move upward into the chest cavity
• In order to reduce the volume of the chest cavity, even the muscles that are located between the ribs can relax
•  When the space in the chest cavity becomes more congested, the air that is rich in carbon is forced out of the lungs and the windpipe, and it is then expelled through the mouth or nose
• As they relax, they bring their rib cage down and in toward themselves. As a result, the ribs move downward during the exhalation process
