So,ERV(Expiratory Reserve volume) decreases. Click Convert has created sales of over $1. What is the volume of air present in the lungs when the lungs are at rest (in between breaths)? Why do we need so many alveoli? Fiber adsorbs (binds) bile so eating a fiber-rich (high fiber) diet would result in more bile binding to fiver and more bile excreted in feces. 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. It does not store any personal data. Explain why the blood pH begins to decrease when physical activity increases. As PCO2 increases it combines with water to form carbonic acid. Explain why swimming is not generally recommended as an exercise to prevent osteoporosis. This means there is more oxygen circulating in the blood for the tissues to take up.
