Respired

To respire means to breathe; to take in oxygen and expel carbon dioxide from the body. This biological process is essential for life in most organisms. It involves the exchange of gases at the cellular level, providing energy through cellular respiration. The mechanics vary from simple diffusion to complex systems like lungs and gills, but the fundamental principle remains the same: the intake of oxygen to sustain life functions and the release of waste products.

Respired meaning with examples

• The hiker, exhausted from the steep climb, respired heavily, drawing deep breaths of the crisp mountain air to replenish his oxygen levels. Each inhale brought him closer to revitalisation.
• Aquatic creatures like fish *respire* through gills, extracting dissolved oxygen from the water. This complex process allows them to thrive in their submerged environments and obtain oxygen needed.
• The patient, experiencing breathing difficulties, struggled to *respire* on their own and required the assistance of a mechanical ventilator to support the delivery of air and gas exchange.
• Plants *respire* during the night, absorbing oxygen and releasing carbon dioxide, a reverse process to photosynthesis that fuels their own metabolic needs. This keeps their survival alive.
• The tiny insects, trapped beneath the glass, could no longer *respire* effectively, as their access to fresh air was severely limited, eventually causing them to become lifeless.
