Respiratory System

Function : to connect nasal cavity to mouth Structure: big space where air can meet

Function: where air goes in Structure: moved air,cleans air and warms

Function: tube that food goes to get to the stomach Structure: a tube that allows food to get to the stomach

Function: air goes through tube to get to lungs Structure: A tube that allows air to travel to lungs has. Is hard on all sides except on so the esophagus can expand into it

Function: to not let food to go into lungs and so air can’t go into a stomach Structure: a flap that either covers the esophagus or the trachea

Function: allows people to talk Structure: air passed through vocal cords and cords vibrate and create sound.

Function site of gas exchange fills up with air Structure is elasticity and allows to expand

Function passage ways for air Structure to transport and keep are clean also so it doesn’t collapse also gas exchange can only happen in small vessels

Function to transport air from the trachea to the lungs Structure filters and doesn’t collapse

Function site of gas exchange Structure encrusted surface area and more efficient gas exchange and must be thin

Function makes lungs exhale and inhale helps with venous return Structure must be strong big also on inhalation creates pressure in abdomen and helps with venous return

Creates mucus

Anti bacterial traps things moistens air transported by cilia

Little hairs that trap things and move around other things
