Breathing and Cellular Respiration

The video explains the process of breathing and cellular respiration, highlighting the importance of oxygen in energy production. It covers how different animals, including humans, perform gaseous exchange. In humans, the respiratory system involves inhalation and exhalation, with oxygen being absorbed in the alveoli. Cellular respiration, which can occur with or without oxygen, is crucial for energy production in cells, particularly during exercise when more ATP is needed.
