| Question | Answer |
| The tube at the back of the throat shared by the respiratory and digestive systems | Pharynx |
| Which of these conditions is an inflammation and infection of the lungs where too much moisture builds up and impairs breathing? | Pneumonia |
| What is oxygenation? | Process by which molecules are loaded onto the hemoglobin molecules in the blood stream |
| What is the name for the windpipe? | Trachea |
| Where the trachea splits into two passages | Carina |
| This element is the reason we breath | Oxygen |
| Small muscles of breathing found between the ribs | Intercostal muscles |
| Describe the process of a cough | No. of particles in the trachea reaches a critical mass which causes an impulse In the vagus nerve. This causes a motor response. Youl take a breath and your vocal cords will close to build up pressure in the trachea. This trigger in the diaphragm will |
| Windpipe. Has "C shape" cartilage to help keep it open | Trachea |
| Normal respiratory rates range from | 12 to 20 breaths/min |
| What is the name of the tiny hairs that filter dust and germs out of the air entering the respiratory system? | Cilia |
| The trachea divides into the left and right primary ______ | Bronchi |
| What occurs when oxygen and carbon dioxide gases are exchanged? | Respiration |
| 4 main vital signs | Body Temperature, Pulse rate, Respiratory rate, Blood pressure |
| What is the function of the oropharynx and where does it lie in the body? | The middle part of the throat connects to the oral cavity (mouth). It allows air, food and fluid to pass through. |
| The smallest of respiratory branches | Bronchiole |
| What is the role of the thyroid cartilage and what is it made off? | it protects and supports the vocal cords. It is made of hyaline cartilage |
| Where is the site of oxygen and carbon dioxide exchange in the lungs? | Bronchioles |
| The maximum amount of air that can be moved into and out of the lungs | Vital Capacity |
| fast respiratory rate (above 20) | tachypnea |
| What are the main functions of the larynx? | • Production of sound and speech • Speech Protection of lower airways |
| Waste product of respiration | Carbon Dioxide |
| Each lung is enclosed in a double-walled sac called the _______ | Pleura |
| What is elasticity? | Elasticity is the ability of the lung to return to its normal shape after each breath. |
| What is external respiration? | the exchange of gases by diffusion between the alveoli and the blood in the alveolar capillaries, across the respiratory membrane. |
| What are the key tissue types in the pharynx called? | • Mucous and submucosa (mucosa associated lymphoid tissue = MALT tissue)- supports fighting infection. • Smooth muscle • Blood and nerve supply |
| What occurs in the capillaries of the alveoli? | Oxygen and carbon dioxide are exchanged |
| Emphysema causes | SOB |
| What is the large flat muscle that separates the thoracic cavity from the abdominal cavity? | Diaphragm |
| Where the esophagus and the trachea branch off. | laryngopharynx |
| Peak expiratory flow readings are | higher when patients are well; lower when patient's airway is constricted |
| What percentage of the air we breathe is made up of oxygen? How much of it does our body use? | 21% , 5% |
| Contains the hard palate and the soft palate. | nasopharynx |
| Which of the following is true of lung cancer? | Leading cause of death in men and women |
| Which of these conditions is the collapse of part or all of a lung? | Atelectasis |
| In what stage of respiration does the exchange of gases between the lungs and the blood occur? | External respiration |
| abbreviation for short of breath | SOB |
| Breathing out | Expiration |
| oropharynx | Contains the base of the tongue, tonsils, and vallecula. |
| What is the name of the flap of tissue that prevents food and liquid from entering the air passages during swallowing? | Epiglottis |
| When are the internal intercostals used? | The internal intercostals are used when expiration becomes active, as in exercise. |
| What is internal respiration? | exchange of gases by diffusion between blood in the capillaries and the body cells |
| Which of these conditions occurs when the bronchial tubes are inflamed and, as a result, obstructed? | Asthma |
| What supply of oxygen exists in the body at any one time? | 4-6 minutes |
| What part of the body does tuberculosis mainly affect? | Lungs |
| What is compliance? | This is the stretchability of the lungs, i.e. the effort required to inflate the alveoli. ' |
| A completely circular ring of cartilage in the upper airway | Cricoid cartilage |
| The amount of air that is breathed in and out at any one time | Tidal Volume |
| Small, leaf-like flap of tissue at the bottom of the laryngopharynx. | epiglottis |
| Breathing in | Inspiration |
| What is surfactant and where is it created? | Created by septal cells. It stops the alveoli drying out and reduces suflace tension, preventing alveolar collapse during expiration |
| What separates the two lungs? | Mediastinum |
| What does smooth muscle do? | It gives part of the body tone. If something is toned, it can stay rigid as opposed to floppy. This maintains airway patency, meaning it helps to keep the airway open by maintaining its shape. |
| absence of breathing | apnea |
| What are they key functions of the Pharynx? | warming and humidifying, Passageway, Hearing, protection, speech |
| How is the respiratory system divided? | two sections: the upper airway and the lower airway |
| What makes up the lower respiratory tract? | Anything from the trachea down |
| What makes up the upper respiratory tract? | Anything from the nose to the larynx |
| What are the main functions of the Trachea? | • Support and patency - whatever way you move your head, your airway should remain open • Mucociliary escalator- it is made up of mucus and cilia. It moves the mucus up and out of the lungs by coughing or swallowing. • Cough reflex |
| Which structure contains the vocal cords? | Larynx |
| Each lung has separate sections called _____ | Lobes |
| Clusters of tiny, thin walled air sacs were gaseous exchange occurs | Alveoli |
| Internal respiration is the transfer of gases between the bloodstream and the cells of the body. | True |
| Volume of air that is left in the lungs after forced expiration | Residual volume |
| Seen from outside as the "Adam's apple" this structure contains the vocal cords | Larynx |
| External respiration is the transfer of oxygen and carbon dioxide between the environment and the bloodstream in the lungs. | True |
| Slow respiratory rate (below 12) | bradypnea |
| What is ventilation? | The physical act of breathing |
| difficulty breathing or labored breathing | dyspnea |
| Air travels through the nostrils into this chamber to be warmed and humidified | Nasal cavity |
| Dome shaped muscle involved in breathing | Diaphragm |
| Brings deoxygenated blood to the lungs from the heart | Pulmonary Artery |
| What is the purpose of the pleura that surrounds the lungs? | Protect from friction |
| Spirometry is one of the most common tests used to diagnose diseases and disorders of the | Respiratory system |
