| 14440808657 | Respiratory Mucosa | Pseudostratified ciliated columnar epithelium Mucous and serous secretions contain lysozyme and defensins Cilia move contaminated mucus posteriorly to throat Inspired air warmed by plexuses of capillaries and veins Sensory nerve endings trigger sneezing Pseudostratified ciliated columnar epithelium Mucous and serous secretions contain lysozyme and defensins Cilia move contaminated mucus posteriorly to throat Inspired air warmed by plexuses of capillaries and veins Sensory nerve endings trigger sneezing | 13 | |

| 14440808659 | Functions of the Nasal Mucosa and Conchae | During inhalation, conchae and nasal mucosa Filter, heat, and moisten air During exhalation these structures Reclaim heat and moisture | 15 | |
| 14440808660 | Paranasal Sinuses | In frontal, sphenoid, ethmoid, and maxillary bones Lighten skull; secrete mucus; help to warm and moisten air | 16 | |

| 14440808663 | Isthmus of fauces | Opening to oral cavity | 19 | |
| 14440808664 | Daltons Law of Partial Pressure | Dalton's law of partial pressures states that the total pressure exerted by a mixture of gases is the sum of the pressures exerted independently by each gas in the mixture. | 20 | |
| 14440808665 | Which form of hypoxia reflects poor O2 delivery resulting from too few RBCs or from RBCs that contain abnormal or too little hemoglobin? | Anemic Hypoxia | 21 | |
| 14440808666 | Which of the following is the primary factor in oxygen attachment to, or release from, hemoglobin? | Partial Pressure of Oxygen | 22 | |
| 14440808667 | Oxygen is unloaded where it is most needed when blood pH drops, this is a phenomenon known as | The Bohr effect | 23 | |
| 14440808668 | Hypoxia can be caused by... | Hyper secretion of EPO | 24 | |
| 14440808669 | Steps of CO2 Transport | CO2 is released from the mitochondria, diffuses into a capillary, carried to lungs, diffuses into alveolus, air exits through nose or mouth | 25 | |
| 14440808670 | Which form of CO2 transport accounts for the least amount of CO2 transported in blood? | Dissolved in plasma | 26 | |
| 14440808671 | What is the most common method of carbon dioxide transport? | As bicarbonate Ions in the plasma | 27 | |
| 14440808672 | What area in the brain sets the respiratory rhythm? | Ventral Respiratory Group | 28 | |
| 14440808673 | Inspiratory neurons send information to the diaphragm via what nerve? | Phrenic Nerve | 29 | |
| 14440808674 | What directly stimulates the central chemoreceptors, thus increasing respiration? | H+ Hydrogen Ions | 30 | |
| 14440808675 | As a result of hyperventilation, what will happen to the partial pressures of CO2 (pCO2) and pH? | Yes, pCO2 would decrease and pH would increase. As CO2 is blown off, H+ would decrease, thus increasing pH. | 31 | |
| 14440808676 | Which receptors inhibit inspiration during hyperinflation of the lungs? | nspiration stimulates the pulmonary stretch receptors (PSRs), which send input to the respiratory centers, inhibiting further inspiration. | 32 | |
| 14440808677 | What stimulates increased respiration at the beginning of exercise? | at the beginning of exercise, blood gases have not changed; thus, other factors such as anticipation of exercise contribute to the increase in respiration. | 33 |
