During inhalation, the diaphragm moves upward decreasing the volume of the thoracic cavity False True

## Step 1<br />The statement given in the problem is "During inhalation, the diaphragm moves upward decreasing the volume of the thoracic cavity."<br /><br />## Step 2<br />To verify the truth of this statement, we need to understand the process of inhalation. During inhalation, the diaphragm, a dome-shaped muscle located at the base of the lungs, contracts and moves downward. This movement increases the volume of the thoracic cavity.<br /><br />## Step 3<br />The increase in the volume of the thoracic cavity leads to a decrease in the pressure within the thoracic cavity. This decrease in pressure allows air to flow into the lungs, which is the process of inhalation.<br /><br />## Step 4<br />Therefore, the statement given in the problem is incorrect. The diaphragm does not move upward during inhalation, but rather downward, increasing the volume of the thoracic cavity.
