Danny Marnell BioE 210 HW #1 1. An engineering approach would be good in this problem because the values in the problem are quantitative, so we would be able to calculate specific variables such as blood oxygen level. We would also be able to determine a specific value of percent oxygen in the air which maximizes visuospatial ability while keeping the heart rate at a safe value. We would be able to calculate limits of the human body without actually having to test it and potentially hurt someone in the process, and be able to find the point at which increased oxygen percentage actually does not help anymore. 2. Extracellular fluids in the body are made up of interstitial fluid (80% of ECF) and plasma (20%

Unformatted text preview: of ECF). Plasma contains plasma proteins, which are not able to pass through the capillary walls, but all other components of plasma pass through, and make up the interstitial fluid. 3. Negative feedback occurs when a change in a variable results in a body response that causes variable to move in opposite direction. The difference that feedforward regulation has from negative feedback is that it anticipates a change in a variable, so the body response to variable change occurs faster. 4. Circadian rhythms become free-running when a subject has been exposed to constant light or constant darkness for an extended period of time, resulting in a change of the subjects normal circadian cycle. 5....
