Question

During exhalation the ribs move ________.

Answer 1

The ribs are a group of twelve paired bones that form the thorax's protective 'cage.' They connect to the vertebral column posteriorly and terminate as cartilage anteriorly (known as costal cartilage). The internal thoracic organs are protected by the ribs, which are part of the bony thorax.

Complete answer:
Breathing is the process of inhaling oxygen-rich air and exhaling carbon dioxide-rich air with the help of respiratory organs. Inhalation is the process of bringing oxygen-rich air into the body and exhalation is the process of releasing carbon dioxide-rich air. It is a continuous process that occurs at all times and throughout an organism's life.
Exhalation is the passive act of exhaling air that has been taken in. The diaphragm expands and moves upward into the chest cavity as it relaxes. The diaphragm rises and the ribs descend and inwards during exhalation, reducing the space in the chest cavity. This increases the air pressure inside the lungs and forces the air out.
During inhalation, the diaphragm moves down and the ribs move up and outwards. This movement expands the space in our chest cavity, allowing more air to enter the lungs. Air is sucked into the lungs. Exhalation causes the ribs to move down and inwards, while the diaphragm rises to its previous position. As a result, the chest cavity shrinks, and the air is forced out of the lungs. These movements in our bodies are easily felt.

Thus, Exhalation causes the ribs to move downward and inward.

Note: Take a deep breath in and out. Keep your palm on your abdomen and feel the movement. Lung damage is caused by smoking. Smoking has also been linked to the development of cancer. It must be avoided at all costs.
