Question

What are the effects and mechanisms of action of CO_2 on respirators movement What are the effects and mechanisms of action of hypoxia on respirators movement? What are the effects and mechanisms of action of dead space on respirators What are the effects and mechanisms of action of a high concentrate respiratory movements? Do the vagus nerves participate in the regulation of respiratory movements. What are the effects and mechanisms of action of the vagus nerves on respiratory movements? From your results, which is the most potent respiratory stimulant?

Explanation / Answer

1. The amount of carbon dioxide in the blood exerts a strong influence on respiratory rate. As your activity level increases, your cells -- especially muscles cells -- produce increased amounts of carbon dioxide. The rhythmicity center in the brainstem detects increased carbon dioxide and increases the respiratory rate to eliminate the excess.

2.Blood oxygen content exerts a secondary influence on respiratory rate. Normally, the blood oxygen level is 80 to 100 mmHg. Respiratory rate is stimulated if it drops below 50. A blood oxygen level below 50 is extremely low, which is why this respiratory control is of secondary importance compared to other mechanisms of respiratory rate regulation.

3. In physiology, dead space is the volume of air which is inhaled that does not take part in the gas exchange. Hence if dead space valu is higher it meand less exchange of gases and in this condition to maintain the sufficient gas exchange, the respiratory rate will increase.

4. High concentration of H+ means low pH value. Sensors called the aortic and carotid bodies detect changes in blood pH. The lungs and kidneys collaboratively control blood pH. An abnormally low blood pH increases the respiratory rate. Rapid breathing releases increased amounts of carbon dioxide, a major determinant of blood pH. If excessive carbon dioxide is expelled through rapid breathing -- such as occurs if you hyperventilate -- you might feel dizzy or faint. Breathing into a paper bag alleviates this feeling because you rebreathe carbon dioxide, bringing the blood level back to normal.

5.The vagus nerve carries the messages to the lungs to constrict the respiratory passageways.

6. Rising CO2 level is the most potent stimulant for respiratory rate.
