| 3 LOBES | How many lobes is the right lung divided into? |
| 2 LOBES | How many lobes is the left lung divided into? |
| CAPILLARIES | small blood vessels with thin walls |
| BRONCHITIS | is an inflammation of the bronchial tubes, or bronchi (the air passages that extend from the windpipe into the lungs). |
| EMPHESYMA | late effect of chronic infection or irritation of the bronchial tubes. |
| ASTHMA | when the airways react by narrowing or obstructing when they become irritated. This makes it difficult for the air to move in and out |
| PNEUMONIA | infection of the lungs, which can be caused by a variety of viruses, bacteria, and parasites. |
| RESPIRATORY SYSTEM | a system of organs functioning in respiration and in humans consisting especially of the nose, nasal passages, pharynx, larynx, trachea, bronchi, and lungs. |
| EPIGLOTTIS | a flap of cartilage at the root of the tongue, which is depressed during swallowing to cover the opening of the windpipe. |
| TRACHEA | a large membranous tube reinforced by rings of cartilage, extending from the larynx to the bronchial tubes and conveying air to and from the lungs; the windpipe |
| DIAPHRAGM | the main muscle in breathing, and is located underneath of the lungs |
| BRONCHI | any of the major air passages of the lungs that diverge from the windpipe. |
| ALVEOLAR | the final branches of the respiratory tree and act as the primary gas exchange units of the lung |
| NOSE | A pathway for oxygen to enter the lungs. Lined with hair and mucus to help filter larger particles from the air we breathe. |
| LUNGS | Organ which allows oxygen to get to the blood and helps remove waste gasses such as carbon dioxide. |
| DIAPHRAGM | Sheet of muscle beneath the lungs that contracts and relaxes which changes the air pressure in the chest cavity to move gasses into and out of the lungs. |
| PHARYNX | muscular funnel passageway used by food, liquid and air, which helps with swallowing. The epiglottis is attached at the base of this tube. |
| ALVEOLI | Clusters of thin-walled sacs surrounded by capillaries that allow for quick exchange of oxygen and carbon dioxide. |
| CILIA | Microscopic hair-like structures that line the nasal cavity, trachea, and bronchi to help filter the air we breathe. |
| LARYNX | piece of cartilage protecting two vocal folds of tissue which allow us to speak. |
| PLEURA | Membrane surrounding the lungs that help the organ slide smoothly against the ribs and muscles |
| PULMONARY | referring to the lungs |
| NASAL CAVITY | place where air enters the body |
| MUCUS | helps moisten, warm and filter the air as it enters the nose; secreted by the mucous membranes |
| TRACHEA | windpipe |
| ALVEOLI | air sacs |
| LOBE | division of the lungs |
| ASPHYXIA | Condition caused by insufficient intake of oxygen |
| RESPIRATION | the bodily process of inhalation and exhalation, distribution of oxygen and removal of carbon dioxide from the cells of the body |
| ALVEOLI | small grape-like clusters found at the end of the each bronchiole; have thin, flexible walls that allow gas exchange between the CV & respiratory system (O2 & CO2) |
| CILIA | hairlike projections that sweep particles towards the throat |
| APNEA | temporary cessation of breathing |
| SEPTUM | divides the nasal cavity into right and left |
| CIRCULATORY AND DIGESTIVE | Which two systems does the Respiratory System work with to release energy to the body? |
| BREATHING | The movement of air into and out of the lungs. |
| THROAT | What is another name for the pharynx? |
| 300 MILLION | About how many alveoli are found in an average adult lung? |
| CARTILAGE RINGS | structure helps keep the airways open |
| EXTERNAL RESPIRATION | gas exchange between alveoli and blood |
| INTERNAL RESPIRATION | gas exchange between blood and cells |
| RHINOPLASTY | surgery that changes shape of the nose |
| PARANASAL SINUSES | small hollow spaces in the bones around the nose |
| NASAL CONCHA | bones that divide the nasal cavity, support mucous membrane, and and increase surface area |
| CELLULAR RESPIRATION | cells need oxygen along with sugar to produce ATP energy |
| MAXILLARY PARANASAL SINUS | The largest among all the paranasal sinuses, these two conical cavities are located on the two sides of the nose, above the upper teeth, and below the cheeks |
| FRONTAL PARANASAL SINUS | Starting from the lower middle part of the forehead, these two sinuses reach over the eyes and eyebrows |
| ETHMOID PARANASAL SINUS | on both sides of the nose, between the eyes |
| SPHENOID PARANASAL SINUS | located near the optic nerve and the pituitary gland on the side of the skull. |
| PARANASAL SINUSES | paired and symmetrical, air-filled cavities situated around the nasal cavity. |
| OTOLARYNGOLOGIST | a doctor that specializes in treating conditions that affect the ears, nose, and throat, as well as head and neck surgery. |
| SURFACTANT | film composed of lipids and proteins prevents alveolar collapse at low lung volume by reducing surface tension |
| HYOID BONE | a highly movable and strong bony anchor for a number of muscles and soft tissue structures in the head and neck |
