Terms | Definitions |
|---|---|
 Primary | _____ function of respiratory system: bring oxygen in and take carbon dioxide out |
| O2 | oxygen |
| CO2 | carbon dioxide |
| external | ____ respiration: occurs in the lungs |
| internal | ____ respiration: occurs all over the body |
| external | ____ respiration: exhange of oxygen and carbon dioxide between the air inhaled into the lungs and the blood flowing through the pulmonary capillaries. |
| Internal | _____ respiration: exchange of oxygen and carbon dioxide between the blood in capillaries all over the body and all of the cells and tissues of the body. |
| secondary | _____ functions of the respiratory system: Voice production, body temperature regulation, acid base balance, sense of smell |
| four | how many secondary functions of the respiratory system are there? |
| voice production | phonation: one of the four secondary functions of the respiratory system |
| voice production | phonation: process begins in the larynx one of the four secondary functions of the respiratory system |
| vocal cords | these (fiberous tissue bands) stretch across the lumen of the larynx and vibrate as air passes over them |
| body | ____ temperature regulation: one of the four secondary functions of the respiratory system |
| cold | ____ situation: network of superficial blood vessels under the nasal passages help warm inhaled air before it reaches the lungs. HELPS PREVENT HYPOTHERMIA |
| Hot | ____ situation: the respiratory system aids in COOLING the animals by mechanisms of PANTING. increases the evaporation of fluid fromt eh lining of the nasal passages |
| Acid | ____ - base balance: one of the four secondary functions of the respiratory system |
| acid base balance | improtant homeostatic mechanism in the body |
| acid base balance | maintains proper blood ph so that body functions properly |
| acid base balance | respiratory system helps regulate the acid base system by controling the amount of CO2 in the blood |
| acid base balance | the more CO2 in the blood, the more acidic(lower ph) the blood will be |
| acidic | more co2 means its acidic or alkalinic? |
| normal | blood pH of 7.4 is normal or abnormal? |
| smell | olfactory sense |
| olfactory sense | one of the four secondary functions of respiratory system; receptors for sense of smell are located in the epithelia of the nasal passages |
