Overview

Respiration is a vital life process that involves the breakdown of food to release energy for all biological activities. The term 'respiration' comes from the Latin word 'respire' meaning 'to breathe'. It encompasses the entire chain of processes from inhalation of air to the use of oxygen in cells.

Key Concepts

Air pathway

Air pathway: Nostrils → Nasal cavity → Pharynx → Larynx → Trachea → Bronchi → Bronchioles → Alveoli. Each structure has specific functions like filtra
