Individual who remain at high altitude for too long can develop chronic mountain sickness. It is characterized by the following clinical sequence: 1. an extremely high hematocrit, 2. an elevated pulmonary arterial pressure and 3. an enlarged right side of the heart. As it progresses, congestive heart failure and death ensues u
Researchers are developing blood substitutes to meet the demand for emergency transfusions. What would be the effect of artificial blood in which binding of O2 is not altered by acidity?
A population of typical neurons is maintained in culture in the lab. The media bathing the neurons has an extracellular concentration of Cl- of 110mmol/L. A particular neuron maintains an intracellular Cl- concentration of 4mmol/L. At what membrane potential could Cl- be closest to electrochemical equilibrium in that cell?
The functions of this division of the nervous system are implied in its name! The ANS regulates the "automatic" functions of body...heartrate, respiration, digestion, just to name a few. Let's describe the structures of the ANS, along with their neural pathways! Then, let's discuss the negative feedback system needed for norm

Compare blood types and the basis for ABO and Rh incompatibilites. Categorize blood type by its characteristics and function.
The presence or absence of testosterone determines whether a mammal will differentiate as a male of female - estrogens have no effect. In birds, it is the opposite: the presence or absence of estrogen is critical. What problems would sex determination by estrogen create if that were the mechanism for mammals? Why do those proble

Humans tend to view cortical mechanisms as preeiminent, probably because we are the species with the largest cortexes. However, you could make the argument that the lower sensorimotor functions are more important. What are some of those arguments?
Pretend you are cleaning your garage but the big door is stuck. You can only move things through the smaller "people" door. So the cars and riding lawn mower have to stay in the garage. This is analogous to the pores in the glomerulus. They are larger than ordinary capillary pores but still not large enough to let everything out
