BIPN 108 Lecture Notes - Lecture 6: Carotid Body, Venous Blood, Vasodilation
Document Summary
Venous blood (no o2) ente arteriole blood (gains o2) Transport through cascade of pressures enters the capillaries --> Alveolar air has a different composition: mixes with h2o, etc. Hemoglobin (bhor effect) ph drops: shifts and lets go of o2. Demonstrated: giving co2 to breath and the breathing rate changes. When you loose a pound of fat it turns into co2. A lot of way co2 is carried is in the equilibrium ( co2 + h2o h2co3) Watch here figure out the shift in ph. Carbonic anhydrase: enzyme that increases the rate of reaction. 7. 2 and 6. 8 change is big change because it is getting regulated. Double bar shows a lot is being ignored. Lactic acid build is correlated to drop in blood ph. As lactic acid is building up ph drops. As ph drops lactic acid is building up. In physiological conditions in blood all lactic acid deprotonates and forms lactate. Physiological (first vertical line), neurological (2nd vertical line)
