Explain the interrelationship between exercise, carbon dioxide, and active hyperemia. Most (~98%) oxygen is transported from the lungs to tissue bound to __________________ within RBCs, forming oxyhemoglobin (HbO2). Explain. Changes in pulmonary elastic and resistive properties, and in maximum expiratory flow with increasing age, were first described 40 yrs ago, admittedly by small cross-sectional studies of young adults versus elderly subjects. Capillarisation occurs. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website.

Analytical cookies are used to understand how visitors interact with the website. The increase in arterial PCO2 and H+ stimulates chemoreceptors resulting in a stimulation of respiratory centers in medulla. Explain why physical exercise promotes lymphatic circulation. VC can be assessed with a spirometer, which is a device used for . Increasing MV is necessary to provide enough oxygen for the ERV decrease with exercise assuming that the volume of air was exhaled more than being inhaled at the time. Thu.
