Introduction The experiment aimed to establish a correlation between caffeine intake and the effects it has on both the pulse and respiration rates of an individual after undergoing moderate-intense cardiovascular exercise. Caffeine itself is one of the most heavily consumed drugs on the planet; it is estimated that over 90% of Americans consume caffeine daily (Richard Lovett‚ 2005‚ New Scientist iss. 2518) and is the most widely used stimulant in the world (Arcerio‚ P‚ Ormsbee‚ J‚ 2009‚ pg. 1)

the efferent radius decreases the glomerular filtration rate. Increasing the efferent radius allows more blood drainage out of the glomerulus and that decreases the amount of blood to be filtered so the glomerular filtration rate will decrease. 6. How did decreasing the efferent radius affect glomerular filtration rate? >> Decreasing the efferent radius increases the glomerular filtration rate. The constriction of the efferent radius will limit blood drainage out of the glomeruli and
