During exercise: IRV will decrease. IC increases with exercise because the body needed more oxygen. Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate cannot bind to the active site or it cannot undergo catalysis. 4 days ago. If a damaged lung loses surfactant, then the other lung can supply the lost surfactant. FRC = RV + ERV. 100% (6 ratings) 7. 7. What happens when the diaphragm contracts?

This approach assumes that the patients can make a truly maximal inspiratory effort during exercise. Tidal volume is the amount of air breathed in with each normal breath. 3 The suggested mechanisms for this include: parasympathetic . Explain why VC does not change with exercise. Using the lab activity, observe and record the physiologic changes that occur during exercising using the following chart: Four interval times (PR, RT, TP and RR) measured in seconds were recorded both with the subject at rest and after the subject had exercised. Due to the increase in blood flow, vasoconstriction of arterioles occurs to maintain mean arterial pressure (Bassett & Edward, 1997). It is the left ventricle that adapts to the greatest extent. copyright 2003-2023 Homework.Study.com. However, at rest, TV is large enough to provide the amount What happens to tidal and residual volume during exercise? There will be more capillaries present so the quicker the oxygen will get to the muscles. For a given PO2, less oxygen is bound to hemoglobin (lower hemoglobin saturation) at a lower (more acidic) pH. b. This increased filling on the left ventricle increases its elastic recoil thus producing a more forceful contraction. A number of factors affect the normal predicted lung volumes and capacities, including _________, ________, _______ and _____________. respiratory volumes 2. 2. the ERV decrease with exercise assuming that the volume of air was exhaled more than being inhaled at the time.
