There are several limitations, systematic and random errors that should be considered when interpreting these results. FEV! Explain how the cardiovascular system transports essentials to and from all cells. The respiratory rate, pulse, blood pressure, P wave, QRS complex and T wave were defined for each subject. If a damaged lung loses surfactant, then the other lung can supply the lost surfactant. the ERV decrease with exercise assuming that the volume of air was exhaled more than being inhaled at the time. A decreased vital capacity is an indication of restrictive lung disease where the lungs cannot expand completely. Due to the increase in blood flow, vasoconstriction of arterioles occurs to maintain mean arterial pressure (Bassett & Edward, 1997). Vital capacity is the maximum amount of air that can be breathed out after breathing in as much air as possible. This means there is more oxygen circulating in the blood for the tissues to take up. Explore the main processes and function of the lungs and learn about the lungs' role in inhaling and exhaling. The main function of the lungs is gaseous exchange. Did tidal volume change between rest and exercise? When you are exercising aerobically, your muscles consume more oxygen and produce more carbon dioxide than they do at rest. How has the heart/lung machine changed health care, patients, and medical professionals? Why? Therefore the main factors impacted in chronic adaptation to exercise are blood flow, and oxygen extraction in the tissues. With Emphysema, if a doctor were to measure all of Evan's pulmonary volumes and capacities, which volume do you predict would be much larger than typically found in a healthy individual? the vital capacity remain the same because it accumulated the tidal. a. Name the muscles involved in increasing the depth of respiration and explain . ~Decrease in elasticity of lungs Explain the effects on pressure and volume during inhalation and exhalation.
