Alveoli
The very small grape like clusters found at the end of each bronchiole. Also known as air sacs. Singular alveolus. The alveoli are where the exchange of oxygen and carbon dioxide takes place. Each lung contains millions if alveoli. During respiration, the alveoli are filled with air from the bronchioles. A network of microscopic pulmonary capillaries surrounds the alveoli. The exchange of oxygen and carbon dioxide between the air inside the alveoli and the blood in the pulmonary capillaries occur through the thin, elastic walls of the alveoli

Emphysema
The progressive, long-term loss of lung function, usually due to smoking. Characterized by a decrease in the total number of alveoli, enlargement of the remaining alveoli, and the progressive destruction of the walls of these remaining alveoli.

TB
Tuberculosis
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 (carbon dioxide and a small amount of water) returned to the lungs by the blood through exhaustion
- Produce the airflow through the larynx that makes speech possible
Upper respiratory tract
Consists of the nose (nostrils), mouth, pharynx, epiglottis, larynx, and trachea
Lower respiratory tract
Consists of the bronchial tree and lungs. Located within and protected by the thoracic cavity
Thoracic cavity
Or thorax. Also known as rib cage. Protects the lower respiratory tract
Airway
Upper respiratory tract and the bronchial tree of the lower respiratory tract
Nasal cavity

Nasal septum
A wall of cartilage that divides the nose into two equal sections
Septum
A wall that separates two chambers
Cilia
The thin hairs located just inside the nostrils, filter incoming air to remove debris
Mucous membranes
These line the nose. These specialized tissues also line the digestive, reproductive, and urinary systems as well as other parts of the respiratory system
Mucus
A slippery secretion produced by the mucous membranes that protects and lubricates these tissues. In the nose, mucus helps moisten, warm, and filter the air as it enters
Mucous
Name of the tissue (which comes first, both anatomically and alphabetically)

Sinus
Can be a sac or cavity in any organ or tissue, the term sinus most commonly refers to the paranasal sinuses
4 pairs of paranasal sinuses
The sinuses are connected to the nasal cavity via short ducts. Located on either side of the nose and are named for the bones in which they are located.
Frontal sinuses
Sphenoid sinuses
Maxillary sinuses
Ethmoid sinuses
Functions of sinuses
- To make the bones of the skull lighter
- To help produce sound by giving resonance to the voice
- To produce mucus to provide lubrication for the tissues of the nasal cavity
Frontal sinuses
Located in the frontal bone just above the eyebrows. An infection here can cause severe pain in this area
Sphenoid sinuses
Located in the sphenoid tissue behind the eye and under the pituitary gland, are closed to the optic nerves, and an infection here can damage vision
Maxillary sinuses
Largest of paranasal sinuses, are located in the Maxillary bones under the eyes. An infection in these sinuses can cause pain in the posterior Maxillary teeth
Ethmoid sinuses
Are located in the erhmoid bone between the nose and the eyes, are irregularly shaped air cells that are separated from the orbital (eye) cavity by only a thin layer of bone
Pharynx
Commonly known as throat. Receives the air after it passes through those or mouth, as well as food
3 divisions of the pharynx
Nasopharynx
Oropharynx
Laryngopharynx
Nasopharynx
First division of the pharynx, is posterior to the nasal cavity and continues downward to behind the mouth. Nas/o means nose, -pharynx means throat. This portion of the pharynx is used only by the respiratory system for the transport of air and opens into the oropharynx
Oropharynx
Second division of the pharynx, is the portion that is visible when looking into the mouth. Or/o means mouth, -pharynx means throat. The oropharynx is shared by the respiratory and digestive systems and transports air, food, and fluids downward to the laryngopharynx
Laryngopharynx
Third division of the pharynx, shared by both the respiratory and digestive systems. Laryng/o means larynx,-pharynx means throat. Air, food, and fluid continue downward to the openings of the esophagus and trachea where air enters the trachea and food and fluids flow into the esophagus
Larynx
Also known as the voice box, a triangular chamber located between the pharynx and the trachea
Thyroid cartilage
The larynx is protected and supported by a series of nine separate cartilages. This cartilage is the largest, and when enlarged it projects from the front of the throat. Commonly known as Adam’s appke
Vocal cords
Part of the larynx. During breathing, the cords are separated to let air pass. During speech, they close together, and sound is produced as air is expelled from the lungs, causing the cords to vibrate against each other
2 protective mechanisms in pharynx to make sure only air enters the lungs
Soft palate
Epiglottis
Aspiration pneumonia
Caused by food or water going into the trachea and entering the lungs instead of going into the esophagus. Risk of blocked airway during swallowing
Soft palate
Muscular posterior portion of the roof of the mouth, moves up and backward during swallowing to close off the nasopharynx. This prevents food or liquid from going up into the nose
