Back

Pressure and Volume are inversely proportional.

Front

What is the common tube for both food and air?

Back

Front

What is the function of the Larynx?

Front

What is the significance of C-shaped rings in the Trachea?

They provide structural support and keep the airway open.

Front

What is the process of inhalation?

Back

The diaphragm contracts, increasing thoracic volume and decreasing pressure, allowing air to flow into the lungs.
