BIO202H5 Lecture Notes - Lecture 3: Partial Pressure, Hemolymph, Sug
Document Summary
Lecture 3: gas transport (1) components of circulatory systems. Air is transported via circulatory system in via structures that bind oxygen in. Hemolymph for insects (2) the bohr effect. The reduction in hemoglobin affinity for o2 caused by decrease in ph and increase in pco2/ co2 concentration (right shift) (3) components of circulatory systems. Hemocyanin high o2 saturation reached at highest po2 (low affinity for. Myoglobin high o2 saturation reached at lowest po2 (high affinity for o2) Hemoglobin o2 affinity intermediate (4) poiseuille"s law. Flow rate through pipe is largely determined by radius of pipe. The larger the radius the faster the flow. Difference in pressure at two ends also important (along with viscosity and type of flow) Pressure and velocity drops with more surface area. Increasing diameter more fluid can pass through pipe increases velocity. Want to slow down velocity in capillaries to allow for diffusion (5) bernoulli"s principle.
