STRUCTURE OF THORAX:

STRUCTURE	DESCRIPTION
RIBS	Bone Structure that Protects Internal Organs such as the Lungs
INTERCOSTAL MUSCLE	Muscles between the Ribs to control it during Inhalation and Exhalation
DIAPHRAGM	Sheet of Muscle at the Bottom of the Thorax that Helps with Inhalation and Exhalation
TRACHEA	Windpipe that Connects the Mouth and Nose to the Lungs
BRONCHI	Thick Tubes that Divides into Two Bronchi, with One Bronchus for Each Lung
BRONCHIOLES	Bronchi will Split to Form Smaller Tubes Called Bronchioles that are in the Lungs, Connected to Alveoli
ALVEOLI	Tiny Air Sacs where Gas Exchange Takes Place
PLEURAL MEMBRANE	Sticks the Outside of the Lungs to Inside of the Chest Cavity so Lungs Follow Chest Movement, Lubricates the Lungs to Reduce Friction
