Respiratory System
| Question | Answer |
|---|---|
| the respiratory system | the body system that deals with breathing |
| oxygen | -needed by every cell in your body to live and function -you breathe this in along with other gases when you inhale -the lungs are two sac-like organs that replace this with the carbon dioxide in your blood |
| brain | controls how you breathe |
| diaphragm | strong, curved muscle attached below the lungs to the lower ribs and backbone |
| chest muscles and diaphragm | -muscles that change the space and pressure inside the body to allow breathing -control the movement of the lungs |
| carbon dioxide | the gas produced by cells |
| exhale | when you breathe out carbon dioxide and other gases |
| involuntary | the type of breathing that you do automatically without thinking about it |
| voluntary | the type of breathing you do when think about and control your breathing |
| cilia | tiny hairlike structures that line your nasal passages and most of the respiratory system |
| pharynx | another name for throat |
| trachea | the windpipe leading to the lungs |
| epiglottis | the flap of tissue that covers the trachea when swallowing |
| larynx | voice box |
| vocal cords | the thickness and length affect the pitch of a sound |
| upper respiratory system | nose, throat, and larynx |
| lungs | -part of the lower respiratory system -the parts of the respiratory system that are sac-like organs that replace the carbon dioxide in your blood with oxygen |
| bronchi | the two tubes that branch off from the trachea |
| trachea and bronchi are lined with... | mucus and cilia |
| respiration | exchange of gases during breathing |
| snore | sound caused by air that cannot move freely and causes parts of the mouth and throat to vibrate and hit together |
| sneeze | irritation to the lining of the airways causes air to be violently released through the nose |
| hiccup | -when the diaphragm muscle contracts quickly, causing short breaths of air and sudden closure of the epiglottis -can happen during an asthma attack because the bronchial tubes become tightened making it difficult to breathe. |
| smoking | -this is harmful because the smoke keeps the cilia and alveoli from working properly -contains poisonous chemicals; can form a sticky tar that keeps the cilia from working properly. |
| allergies | can cause a person to have difficulty breathing when around dust, pollen, or other particles in the air |
| pneumonia | when the lungs become infected |
| Why should Christian take care of their bodies? | - it is their responsibility and glorifies God, the one who made them. |
| asthma | a respiratory disorder that often causes the muscles around the bronchial tubes to tighten more than normal, making it difficult for a person to breathe |
| respiratory diseases | some examples are flu, strep throat, and bronchitis |
| capillaries | tiny blood vessels that surround the alveoli |
| alveoli | tiny air sacs in the lungs |
| inhale | breathing in oxygen and other gases |
| path that air takes when exhaled to create speech | 1. air goes upward from the lungs 2. air goes into the trachea 3. air pushes through the vocal cords 4. the vocal cords vibrate and produce sound waves |
