To answer the question regarding the important parts involved in creating a pressure gradient between the lungs and the atmosphere during normal respiration, we can break down the process into several key components: ### Step-by-Step Solution: 1. **Diaphragm**: - The diaphragm is a dome-shaped muscle located at the base of the thoracic cavity. During inhalation (inspiration), the diaphragm contracts and moves downward, increasing the volume of the thoracic cavity. This action decreases the pressure inside the lungs compared to the atmospheric pressure, allowing air to flow into the lungs. 2. **Intercostal Muscles**: ...

Asertiion : Inspirations occurs when there is a negative pressure in the lungs with respect to the atmospheric pressure. Reason : During inspiration, a decrease in pulmonary volume increases the intre-pulmonary pressure than atmospheric pressure which forces the air from outside to moe into the lungs.
