1. Why was Oxygen consumption increased during exercise?
As you work out or perform certain exercises, your body needs to feed your muscles with blood and
oxygen in order to keep them functioning properly. This oxygen h
Lab 2: Neurosim
1. The resting membrane potential depolarized little by little because the concentration gradient for
potassium inside the cell was stronger, so more potassium left depolarizing the cell.
2. More potassium outside the cell woul
1. How did VT, IRV and ERV change after the subject exercised? What physiological modifications
occurred to create these changes? Which respiratory muscles were involved at rest and after

1. The lag is a result, because it takes some time it takes for action potential to
move down T tubules, cross sarcoplasmic reticulum to release the calcium
from the sarcoplasmic reticulum

1. A symptom of diabetes mellitus is glucose in the urine (glucosuria). Explain the mechanism
responsible for glucosuria with diabetes.
Ideally urine should not contain glucose because the kidneys reabsorbe the filtered glucose i
Endocrine System Physiology:
1. From the data you collected do you see any subjects in the control group who might be at risk
of developing Type 2 diabetes?
We did not see anyone at risk of developing type-2 diabetes. Glucose levels for members of
