RESPIRATORY SYSTEM

ORGANS AND THEIR JOBS

• Bronchial tubes carry air to each lung
• Lungs pump air
• The esophagus prevents food from entering the lungs
• The trachea is a tube that the air moves through

CONTINUED

• The nose and mouth both contribute to getting air in the body
• Sinuses provide space for air to move through
• Two bronchi com off the trachea and go into each lung
• The diaphragm contacts so lungs can move

THING YOU SHOULD KNOW

• Cellular respiration use oxygen to give us energy but then we release C02
• The respiratory system is meant to cycle air though us and give us energy
• This system interacts with the skeletal system because the ribs protect it and the circulatory system because breathing helps move blood

MORE THINGS TO KNOW

• THERE ARE TWO SPECIALIZED CELLS IN THE Respiratory system
• They are mesenchymal and epithelial
• Both of them help make op the lungs.
