1a.) How does breathing alter PCO2 levels in the blood? Explain how this works.
1b.) In relation to this, Why does Restrictive Disease alter vital capacity?
Homework Answers
Dear student,
1a) when there is decreased ventilation , the arterial pCO2 increases which causes a decrease in blood pH . Then the chemoreceptors come into action and they influence the respiratory muscles through spinal cord motor neurons and causes an increased ventilation resulting in decreased pCO2 .
2) Restrictive lung disease affects the vital capacity. Restrictive diseases causes decrease in FEV1( forced expiratory volume in 1 second) and FVC ( forced vital capacity) resulting in FEV1/ FVC ratio to a value of greater than 80% .
Hope this helps you ???

Case Study num22 please answer 1-6 Diabetes Mellitus Diabetes mellitus is a common chronic disease, and every health professional will need to understand how it works and identify common emergency situations related to it. But an equally important part of the health professional's role is patient education and explaining what happens in the disease process. After they go home, diabetes patients will have to manage this complex disease every day. You are working in the free clinic when Father X...
