• RATEHCA -Trachea is also known as wind pipe. It helps in the passage of oxygen rich air towards the lungs from the nose.
• HMARDAIGP- Diaphragm is the musular partition present between the thoracic and abdominal cavity. It helps in breathing by expanding and contracting the thoracic cavity and consequently, the lungs.
• YXRNAPH- Pharynx provides passage to both food and air. The wind pipe is present in front of the food pipe and there is a lid at the beginning of wind pipe which closes during the passage of food and prevents the entry of food particles into wind pipe.
• EILAOVL- Alveoli - Lungs are made up of many small compartments, called alveoli. They help in exchange of gases.
• TIOHANINAL- Inhalation is the taking in of oxygen rich air through the nose and passing it towards the lungs through the trachea.
