Respiratory (LAB)
Dr. Cutler AP2, GTCC
| Term | Definition |
|---|---|
| Which respiratory system is above the vocal cords? | Upper |
| Which respiratory system is below the vocal cords? | Lower |
| What divides the upper and lower respiratory system? | Vocal Chords |
| What is the reason air swirls in and out nasal turbines (conchae)? | To clean the air |
| What cartilage enclose the vocal cords? | Thyroid & Cricoid Cartilage |
| If a vocal cord is thin, is it high or low? | High |
| If a vocal cord is thick, is it high or low? | Low |
| What ligament is used as a safety mechanism to "pop stuff up" or is the cause for someone to "choke on spit"? | Vestibular Ligaments |
| What is the average breaths per min? | 12-20 |
| High Volume = ____ pressure Low Volume = ____ pressure | Low High |
| 1 atmospheric pressure (ATM) = ____ mmHg | 760mmHg |
| What is a tool used to measure respiratory volumes? | Spirometer |
| Which lung volume is the average amount of air you move in and out of your lungs during normal breathing of one respiratory cycle? (500mL) | Tidal Volume |
| Which lung volume is the amount of air you can take in over and over above the normal tidal volume? (Cough) | Inspiratory Reserve Volume |
| Which lung volume is the amount of air you can forcefully exhale after one normal respiratory cycle? (Exhale) | Expiratory Reserve Volume |
| Which lung volume is the amount of air that cannot be forcefully be exhaled and prevents the lungs from collapsing? | Residual Volume |
| Which lung is the amount of residual air out of the total RV of 1200mL that stays in the lung even if it collapses? | Minimal Volume |
| Which lung volume is the maximum amount of air that can be exhaled after a minimum inhale? | Vital Capacity |
| Which lung volume is the vital capacity added to the residual Volume? | Total Lung Capacity |
| What is the amount of air exchanged between the lungs and the environment in one minute? | Minute Volume |
| How do you find respiratory minute volume? | RR x TV = mL Ex. 12 breaths per minute x 500mL = 6000mL/min |
| What is the average minute volume for males and females? | 6L for males 4.5L for females |
| What law is known as high vol = low pressure, low vol = high pressure? | Boils Law |
