Breathing In
• Also know as inhaling• Lesser carbon dioxide, lesser water vapor and
lesser heat• More oxygen• The ribs expand, the diaphragm moves
downwards, the chest expands

Breathing Out
• Also known as exhaling• More carbon dioxide, more water vapor and
more heat• Lesser oxygen• The ribs contract, the diaphragm moves
upwards, the chest contracts

Respiration
• Reaction in cells when oxygen and nutrients are used to produce carbon dioxide and energy

Parts of the Respiratory System
• Nose• Windpipe• Lungs• Air Sacs

Nose
• Allows air to enter and leave the body• Contains hair and mucus to trap the dust in
the air• Air that passes through is moistened and
warmed

Windpipe
• Transfer the air that the nose breathed in into the lungs

Lungs
• Contains air sacs• Allow exchange of gases • Pick up oxygen from inhaled air• Pass carbon dioxide into exhaled air

Air Sacs
• Richly supplied with blood vessels• Increases the surface area for exchange of
gases• Collects oxygen• Release carbon dioxide from the blood vessels
through the walls of the air sacs
