Define and give the function of:
a) diaphragm -
b) trachea -
c) epiglottis -
d) nasal cavities -
e) larynx -
1.) Diaphragm- is a thin skeletal muscle that sits at the base of the chest and
separates the abdomen from the chest. It contracts and flattens when you
inhale. This creates a vacuum effect that pulls air into the lungs. When you
exhale, the diaphragm relaxes and the air is pushed out of lungs.
2.) Trachea- is a wide, hollow tube that connects the larynx (or voice box) to
the bronchi of the lungs. It is an integral part of the body's airway and has the
vital function of providing air flow to and from the lungs for respiration.
3.) Epiglottis- is a leaf-shaped flap of cartilage located behind the tongue, at
the top of the larynx, or voice box. The main function of the epiglottis is to seal
off the windpipe during eating, so that food is not accidentally inhaled to cause
aspiration.
4.) Nasal Cavity- is a hollow space within the nose and skull that is lined with
hairs and mucus membrane. The function of the nasal cavity is to warm,
moisturize, and filter air entering the body before it reaches the lungs.
5.) Larynx- is a tough, flexible segment of the respiratory tract connecting the
pharynx to the trachea in the neck. It plays a vital role in the respiratory tract
by allowing air to pass through it while keeping food and drink from blocking
the airway. It also houses the vocal folds, and manipulates our pitch and
volume, which is essential for phonation and is situated just below where the
tract of the pharynx splits into the trachea and the esophagus.

Label the artificial thorax with the correct anatomical terms by putting the name
of the structure beside the associated letter. This image is a bit different than
what you created as it has 2 balloons inside, but is essentially representing the
same structures.
