The Guide to the Respiratory System, By Addie and Sam

Sam: Their are 2 main parts to the respiratory system are the conduction portion and the respiratory system.

Me: The  conducting portion consists of the air-transmitting passages of the nose, nasopharynx ,larynx,trachea,bronchi and bronchioles. Sam: The part of the face or facial region in humans and certain animals that contains the nostrils and the organs of smell and functions as the usual passageway for air in respiration: in humans it is a prominence in the center of the face formed of bone and cartilage, serving also to modify or modulate the voice.

Me: The nasopharynx is the part of the pharynx behind and above the soft palate, directly continuous with the nasal passages.

Sam: The larynx is a muscular and cartilaginous structure lined with mucous membrane at the upper part of the trachea in humans, in which the vocal cords are located.

Me: The trachea is a tube in humans and other air-breathing vertebrates extending from the larynx to the bronchi, serving as the principal passage for conveying air to and from the lungs; the windpipe.

Sam: The bronchioles is any of the small, thin-walled tubes that branch from a bronchus and end in the alveolar sacs of the lung.

Me: The lungs are either of two spongy, saclike respiratory organs in most vertebrates, occupying the chest cavity together with the heart and functioning to remove carbon dioxide from the blood and provide it with oxygen.

Sam: The mouth or oral cavity opening through which an animal or human takes in food.

__ Me: The 5 main functions of the system are: Respiration/Gas Exchange, Warms and humidifies inspired air, Filters inspired air, Phonation (producing sounds), Olfaction (Smell):    __
