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 |
