A & P - Resp System
A & P - Respiratory System
| Question | Answer |
|---|---|
| The lungs are found resting above this muscle that contracts causing air to enter the lungs during inhalation | diaphragm |
| The top of the lungs is called this | apex |
| These membranes are found covering the lungs and covering the inside of the thoracic cavity | pleura |
| This is the portion of the respiratory track that is also a passage for food, it connects the mouth & nose | pharynx |
| How many lobes are on the right side of the lungs? | three |
| The respiratory center that ultimately controls breathing is found in this section of the brain | medulla oblongata |
| The concentration of this substance in the blood is the primary chemical stimulus for breathing | carbon dioxide |
| During exhalation the diaphragm and rib muscles do this | relax |
| The normal breathing rate for a healthy adult is 12-20 breaths per what? | minute |
| This structure in the respiratory tract, along with mucus and cilia, prevents pathogens from entering the body | tonsils |
| This substance found in the lungs prevents them from collapsing | surfactant |
| This is the process by which gas exchange in the lungs occurs | diffusion |
| This term describes the volume of air in a normal breath | tidal |
| This tube that directs air to the brochiole is found in the lower respiratory tract | trachea |
| This cavity is responsible for filtering, warming, and moistening air entering the lungs | nasal |
| If this structure fails to cover the entrance to the trachea, food may enter the windpipe and cause the person to cough or choke | epiglottis |
| This structure is the voicebox; ot contains vocal cords to produce sound | larynx |
| The actual exchange of gases occurs here | alveoli |
| These are branches in the bronchi of the lungs | bronchioles |
| These are branches of the windpipe that lead to the lungs | bronchi |
| hemoglobin | |
| In this respiratory disorder the alveoli walls burst or fuse, reducing the surface area for gas exchange | emphysema |
| This is the leading cause of emphysema, chronic bronchitis, and lung cancer. | smoking |
| This disease causes the bronchi and bronchioles to spasm because of irritants such as dust and pet dander, causing narrowed, sometimes mucous filled airways and wheezing | asthma |
| During inhalation the diaphragm _________ and flattens | contracts |
| This diseases causes tumors to grow in the lungs that can eventually spread to other body parts during its later stages | lung cancer |
| This respiratory disorder is characterized by inflammation and narrowing of the airways by increased mucus production because of contact with pollutants or smoking | chronic bronchitis |
| Lung cancer can be treated by removing a lung or lobe of the lungs, with chemotherapy, or with _______. | radiation |
| What is the sequence when tracing the path of air in the respiratory tract? | pharynx, larynx, trachea, bronchi, bronchioles |
