Explain why, You muscles require more O2 when exercising. How does the size of the lungs affect exercise performance? In respiratory physiology, if alveolar volume decreases, what happens to alveolar pressure? The first is how rapidly and deeply the individual is breathing: Someone who is hyperventilating will blow off more CO2, leading to lower pCO2 levels. Therefore, blood glucose levels would not increase as rapidly after a fiber-rich meal. high fiber reduce serum cholesterol level. During strenuous exercise, TV plateaus at about 60% of VC but minute ventilation continues to increase. "Emphysema results in increased compliance of the lungs, so that it does not generate enough recoil, making it difficult for the lungs to return to resting volume. Explain in detail why height is typically the most important determinant of Vital Capacity (VC). Course Hero is not sponsored or endorsed by any college or university.

Lungs are the paired organs that are located on either side of the chest. Due to the increase in blood flow, vasoconstriction of arterioles occurs to maintain mean arterial pressure (Bassett & Edward, 1997). Since TLC and RV do not change with exercise, neither does VC. A persons stroke volume will also increase as an increase in blood plasma and blood volume occur and reduced heart rate which increases the diastolic filling time. Since RV does Ventilation increases: increased rate of breathing and increased depth of breaths. Explain the relationship between lung . systemic capillaries carbon dioxide diffuses into the capillaries resulting in a decrease in pH. a.

What are some examples of how providers can receive incentives? I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. Students will respond with answers suggesting increases in heart rate, respiration, sweating and muscle fatigue, as well as muscle soreness as normal. If the ability of the lungs to perform gaseous exchange is reduced, it can lead to lung problems. When the person does general regular exercises, the vital capacity will not change.
