Functions of the respiratory system
- Deliver air to the lungs
- Convey oxygen from the inhaled air to the blood for delivery to the body cells.
- Expel the waste products returned to the longs by the blood through exhalation.
- Reduce the airflow through the larynx that makes speach possible.
Nasal septum
A wall of cartilage that divides the nose into two equal sections.
Cilia
The thin hair is located just inside the nostrils, filter incoming air to remove debris.
Mucas membranes
Line the nose.
Mucus
It’s slippery secretion produced by the mucous membranes that protects and lubricates these tissues.
Olfactory receptors
Nerve endings that act as the receptors for the sense of smell.
Adenoids
Help protect the body from infection coming through the nose or mouth.
para-
Near
Paranasal sinuses
Air filled cavity is lined with mucous membranes, are located in the bones of the skull.
Pharynx
Throat/ receives the air after it passes through the nose or mouth, as well as food.
-pharynx
Throat
or/o
Mouth
Larynx
Voice box/Contains the vocal cords. During breathing the cords are separated to let air pass. During speech, they close together and sound is produced as a raise expelled from the lungs, causing the chords to vibrate against each other.
Epiglottis
Swings down word and closes off the laryngopharynx so that food does not enter the trachea and lungs.
Trachea
Transports air to and from the lungs.
Bronchi
Two large tubes which branch out from the trachea and convey air into the two lungs.
Bronchioles
Smallest branches of bronchi.
Alveoli
Air sacs/ where are the exchange of oxygen and carbon dioxide takes place.
Pleura
The thin, moist, and slippery membrane that covers the outer surface of the lungs and lines the inner surface of the thoracic cavity.
Diaphragm
The contraction and relaxation of the muscle that makes breathing possible.
Phrenic nerves
Stimulate the diaphragm and cause it to contract.
External respiration
The act of bringing air in and out of the lungs from the outside environment.
Internal respiration
Exchange of gases within the cells of the blood and tissues.
Airway inflammation
The swelling and clogging of the bronchial tubes with mucus.
-rrhagia
Bleeding
-ecstasis
Stretching or enlargement
-dynia
Pain
Empyema
A collection of pus in the body cavity.
