Description: Hemoglobin is a protein which binds oxygen in the lungs and releases it in the capillaries. Interestingly, your body controls this intake and drop off of oxygen by having different pHâs at the two locations.

Instructions: For this presentation, your goal is to walk the audience through how oxygen binds to heme (and if any structural changes occur) along with explaining the binding capacity of oxygen to heme in the lungs and how that differs from that in the capillaries. Also explain how CO2 interacting with water can affect the pH of the capillaries.

Feel free to use images from the book or the internet to illustrate your point. Presentations should be around 5-10 minutes.

1. Cerebrospinal fluid is separated from the body by what isknown as the blood-brain barrier. Yet changes in arterial PCO2cause a proportional response in cerebrospinal fluid PCO2. Why isthis?

A. The cells forming the capillaries in the brain contain CO2channels which allow CO2 into the CSF via diffusion.

B. The cells forming the capillaries in the brain contain CO2channels which allow CO2 into the CSF via facilitateddiffusion.

C. CO2 is actively transportedinto the CSF using ATPase pumps.

D. CO2 is not restricted bycapillary barriers.
