structure and function of respiratory system
•Nose
•Pharynx
•Larynx
•Trachea (windpipe)
•Tube that extends from lower edge of the larynx downward into the thoracic cavity
•Rings of cartilage to help keep airways open
•Bronchi
•Bronchial tree
•Lower part of the trachea that divides into the right and left bronchi, bronchioles, and alveoli
•Transport of air from the trachea over a wide area as quickly as possible
•Bronchioles
•Smaller divisions of the bronchi
•Walls composed of smooth muscle to allow contraction and expansion, thereby regulating
airflow to the alveoli
•Lungs
•Alveoli
•Tiny sacs located at the end of the alveolar ducts
•O2 and CO2 exchange between the alveolus and the capillary surrounding it
•Loss of alveolar wall elasticity from respiratory disease, making breathing difficult, especially
when exhaling
,•Respiration
•External
•Internal
•Other functions (with help of the cardiovascular system)
•Transport of O2 to body cells
•Removal of CO2, a waste product of cell metabolism
Name the main structures of the respiratory system
nose, pharynx, larynx, trachea, bronchi, lungs
Name the smaller branches of the bronchi.
bronchioles
Name the tiny air sacs in the lungs
alveoli
What do abbreviations O2 and CO2 mean?
O2 means oxygen; CO2 means carbon dioxide.
what body system helps the respiratory system transport O2 and remove CO2 from body cells?
cardiovascular system
, what does the abbreviation COPD mean?
chronic obstructive pulmonary disease
alveolus
alveol/o
larynx
laryng/o
nose
nas/o, rhin/o
pleura
