This air cannot be expelled and it helps keep the alveoli (the small air sacs that make up the lungs) open at all times. A spirometer will be used to measure respiratory volumes and breathing rate in three female Caucasian subjects that are 25 years of age and 65 inches tall. After a small period of rest, the heart rate and breathing rate both decreased to a point close to their resting rate. Vital capacity (VC) is an easily obtained measurement with spirometry, which, when decreased, points to respiratory muscle weakness. What effect does pulmonary edema have on blood oxygenation? During strenuous exercise, TV plateaus at about 60% of VC but minute ventilation continues to increase. A persons venous return increases due to the higher cardiac output. When the person does general regular exercises, the vital capacity will not change. Explain how hyperventilation and hypoventilation alter levels of carbon dioxide in the blood. However the optimum is not the same for each enzyme. Explain why the heart can be considered the muscle with the greatest elastic strength.

Explain the biological role of adaptive and innate immunity in vaccination. b. the ERV decrease with exercise assuming that the volume of air was exhaled more than being inhaled at the time. "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. and MVV are flow rates so they will be low. Lung Volumes. Chemoreceptors sense the increase in pH and decrease in ventilatory drive. 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. 20 c. 50 d. 80, What respiratory volume represents the total amount of exchangeable air?

One of the test subjects is an endurance athlete and the other does not compete in any sport. a. Did the inspiratory reserve volume increase, decrease, or not change with exercise? During exercise there is an increase in cardiac output, which corresponds to an increase in maximal oxygen consumption. A number of factors affect the normal predicted lung volumes and capacities, including _________, ________, _______ and _____________. Explain. This is the increased amount of capillaries over the muscles which mean more blood flows which will give you more oxygen, and nutrients so you will be able to participate in the exercise longer. Expiratory reserve volume decreased with exercise because greater respiratory effort forced more air out of the lungs with each exhalation. Explain the following statement. high fiber reduce serum cholesterol level. However whilst breathing, my breathing rate was not normal but it was essential for me to keep the results reliable. 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. Breathing rate and the following volumes, Question: Emphysema causes alveolar dilation and destruction of alveolar walls which causes an increase in residual volume with air that cannot be exhaled.
