A quick overview of the p-value.

Short and sweet. Next up… ANOVA.



Question 1 (Physiology) 

Discuss acid base regulation under the following headings:

i) Buffer systems

ii) Ventilation response to change of pH

iii) Renal response to change in pH

Question 2 (Pharmacology)

i) Discuss the mechanism of action of furosemide.

ii) What is the effect of furosemide on the acid base regulation.

Question 3 (physics)
