When blood flows through Microeconomics analyzes what's viewed as basic elements in the economy, including individual agents and markets, their interactions, and . All rights reserved. Ans.2)The IRV acts as a reservoir of extra lung volume that can become inflated with air as we need it, such as when there is a demand for more oxygen inhalation and CO2 exhalation during exercise . 2. Which of the following is typical of progressive emphysema? Taking part in regular aerobic exercise has been shown to increase a persons vital capacity. There will be more capillaries present so the quicker the oxygen will get to the muscles. If, like bile, fiber adsorbs (binds) glucose, then glucose binding to fiber would decrease the amount of glucose available to be absorbed by the Explain why vital capacity (VC) and total lung capacity (TLC) do not change with exercise. Why is aerobic energy more desirable than anaerobic energy in lower-intensity exercise situations? The PR and RT intervals remained virtually unchanged with the PR intervals remaining the same both before and after exercise with an interval time of 0.15 seconds, and the RT interval increase by 0.01 seconds from 0.37 at rest to 0.38 seconds after exercise.
