Sc131 Unit 4 Assignment

LABORATORY REPORT Activity: Respiratory Volumes Name: Learline McGee Instructor: Sharon Marusiak Date: 02.23.2015 Predictions During exercise TV will increase During exercise IRV will increase During exercise ERV will decrease During exercise VC will decrease During exercise TLC will increase Materials and Methods Dependent Variable respiratory volumes Independent Variable level of physical activity [resting or exercising] Controlled Variables sex, age, height 4. Which respiratory volume was calculated? TV, ERV, IRV, RV, BR 5. What was the purpose of the nose clip? So that they were only using there lungs Results Table 2: Average Breathing Rates and Lung Volumes Resting Values Exercising Values Breathing Rate TV(L) ERV(L) IRV(L) RV(L) Breathing Rate TV(L) ERV(L) IRV(L) RV(L) Subject1 11.0 0.5 1.5 2.3 1.6 28.4 1.7 0.6 1.9 1.6 Subject2 11.8 0.5 1.4 2.2 1.6 26.4 1.8 0.7 1.7 1.6 Subject3 11.9 0.5 1.3 2.4 1.6 28.4 1.6 0.6 1.9 1.6 Averages 11.6 0.5 1.4 2.3 1.6 27.7 1.7 0.6 1.8 1.6 Laboratory Report/ Learline McGee/ Respiratory Volumes/ Sharon Marusiak/ 02.23.2015/ Page [1] of [4]

LABORATORY REPORT Activity: Respiratory Volumes Name: Brooke Griffin Instructor: Marcus Collins Date: 10.18.2015 Predictions During exercise TV will increase During exercise IRV will increase During exercise ERV will increase During exercise VC will decrease During exercise TLC will not change Materials and Methods Dependent Variable respiratory volumes Independent Variable level of physical activity [resting or exercising] Controlled Variables sex, age, height 4. Which respiratory volume was calculated? undefined 5. What was the purpose of the nose clip? so the subjects can have labored breathing Results Table 2: Average Breathing Rates and Lung Volumes Resting Values Exercising Values Breathing Rate TV(L) ERV(L) IRV(L) RV(L) Breathing Rate TV(L) ERV(L) IRV(L) RV(L) Subject1 13.4 0.5 1.3 2.1 1.6 27.4 1.6 0.6 1.8 1.6 Subject2 11.8 0.4 1.5 2.2 1.6 29.6 1.6 0.7 2.0 1.6 Subject3 10.4 0.5 1.5 2.4 1.6 27.4 1.7 0.6 1.8 1.6 Averages 11.9 0.5 1.4 2.2 1.6 28.1 1.6 0.6 1.9 1.6 Laboratory Report/ Brooke Griffin/ Respiratory Volumes/ Marcus Collins/ 10.18.2015/ Page [1] of [4]
