Ch 7 The Respiratory System
Overview

Nose- nas/o- Exchanges air during inhaling and exhaling; warms, moisturizes,
and filters inhaled air.

Sinuses- sinus/o- Provides mucus, makes bones of the skull lighter, aids in
sound production.

Epiglottis- epiglott/o- Closes off the trachea during swallowing.

Pharynx- pharyng/o- Transports air to and from the nose to the trachea.

Larynx- laryng/o- Makes speech possible.

Trachea- trache/o- Transports air to and from the pharynx to the bronchi.

Bronchi- bronch/o, bronchi/o- Transports air from the trachea into the lungs.

Bronchioles- the smallest branches at the end of the bronchi

Lungs- pneum/o, pneumon/o- Brings oxygen into the body and removes some
water waste from the body
Lungs- pneum/o, pneumon/o- Brings oxygen into the body and removes
some water waste from the body
Alveoli- alveol/o- Air sacs that exchange gases with the pulmonary
capillary blood.
Diaphragm- A dome-shaped sheet of muscle and tendon that serves as the
main muscle of respiration and plays a vital role in the breathing process.
Pleura: Membrane space between the lungs and diaphragm
