Inspiration Process and Movement of Ribs
During the process of breathing, inspiration refers to the intake of air into the lungs. This process involves the movement of various muscles, including the diaphragm and the intercostal muscles, which results in a change in the volume and pressure in the chest cavity.
Ribs Movement During Inspiration:
During inspiration, the ribs move in a specific manner to allow the expansion of the chest cavity, creating more space for the lungs to expand and fill with air. The correct answer to the question is option D, which states that the ribs move upward and outward.
Movement of Ribs during Inspiration:
The movement of the ribs during inspiration can be explained as follows:
1. Upward Movement: The ribs are attached to the vertebral column at the back and to the sternum at the front. During inspiration, the diaphragm contracts and moves downwards, causing the floor of the chest cavity to descend. This downward movement of the diaphragm pulls the lower ribs upward, expanding the chest cavity vertically.
2. Outward Movement: The intercostal muscles, which are located between the ribs, also play a role in the movement of the ribs during inspiration. These muscles contract, causing the ribs to move outward. This outward movement of the ribs expands the chest cavity horizontally.
Result of Ribs Movement:
The combined upward and outward movement of the ribs during inspiration increases the volume of the chest cavity. As a result, the pressure inside the lungs decreases, creating a pressure difference between the outside air and the inside of the lungs. This pressure difference allows air to flow into the lungs, filling them with fresh oxygen.
Conclusion:
During the process of inspiration, the correct movement of the ribs is upward and outward. This movement, along with the contraction of the diaphragm and intercostal muscles, allows for the expansion of the chest cavity and the intake of air into the lungs.
