Question: During inhalation, the pressure in the thoracic cavity: (2022)

Options:

  1. Increases
  2. Decreases
  3. Remains constant
  4. Fluctuates

Correct Answer: Decreases

Exam Year: 2022

Solution: 

During inhalation, the diaphragm contracts, increasing the volume of the thoracic cavity and decreasing the pressure, allowing air to flow in.

Questions & Step-by-Step Solutions

During inhalation, the pressure in the thoracic cavity: (2022)
  • Step 1: The diaphragm, a muscle under your lungs, moves downwards.
  • Step 2: When the diaphragm moves down, it makes more space in the thoracic cavity (the area where your lungs are).
  • Step 3: As the space increases, the pressure inside the thoracic cavity decreases.
  • Step 4: Because the pressure is lower inside the thoracic cavity than outside, air from outside flows into the lungs.
  • Inhalation Mechanics – Inhalation involves the contraction of the diaphragm, which increases thoracic cavity volume and decreases pressure, facilitating air intake.
  • Pressure-Volume Relationship – According to Boyle's Law, an increase in volume leads to a decrease in pressure, which is crucial for understanding respiratory mechanics.
