Step by step
Solved in 3 steps
- State a hypothesis that explains why all animals have chemoreceptors.Discuss Tidal, residual, minimal air in Gaseous Exchange in AnimalsWhich of the following statements regarding control of respiration is TRUE? At high altitude, a decrease in PC02 of the blood stimulates an increase in ventilation. An increase in the HCO3- concentration in blood stimulates ventilation. A slight decrease in arterial PO2 is a stronger stimulus for increased ventilation than is a comparable decrease in arterial PCO2. The most important signal for regulating ventilation is the H+ concentration of arterial blood. Increased concentrations of lactic acid stimulate ventilation primarily by acting on peripheral chemoreceptors.
- Explain mechanistically how hyperventilation alters the oxygencascade of an animal.After a person hyperventilates (such as by holding their breath), what can be detected on a molecular level? a. decrease in oxygen is detected by both central and peripheral chemoreceptors b. increase in oxygen is detected by both central and peripheral chemoreceptors c. increase in carbon dioxide is detected by both central and peripheral chemoreceptors d. decrease in carbon dioxide is detected by both central and peripheral chemoreceptorsWhat happens to the ventilation rate during exercise? Briefly describe and explain how the chemoreceptors work during exercise .
- When researchers first discovered that airflow through a bird’s paleopulmonal parabronchi is unidirectional, the question arose as to whether gas exchange is countercurrent, cocurrent, or cross- current. Some ingenious investigators carried out experiments in which they measured the efficiency of gas exchange between air and blood in duck lungs when parabronchial airflow was in its normal direction and when the direction of parabronchial airflow was artificially reversed. The efficiency did not change. How is this evidence against countercurrent and cocurrent gas exchange? How is this evidence for cross-current exchange?Discuss the pathway of air through the respiratory system of vertebrateName the neural mechanisms that can modify the normal rhythmic pattern of ventilation
