Example Question #1 : Help With Other Excretory Physiology
Why are women more prone to urinary tract infections compared to males?
They have shorter urethras than men
Their levels of estrogen make their immune systems weaker
Men have specialized white blood cells in the urethra that women lack
Women have smaller bladders compared to men
They have shorter urethras than men
Because women have smaller urethras, bacteria and other pathogens have a shorter distance to travel in order to cause infections in the body. In addition, the proximity of the anus to the urethral opening in women is much closer compared to men, resulting in a closer proximity to bacteria.
Example Question #2 : Help With Other Excretory Physiology
Total body water is approximately __________ of body weight.
40%
85%
60%
20%
60%
Total body water is approximately 60% of body weight. The percentage of total body water is highest in newborns and adult males, and lowest in adult females and in adults with large amounts of adipose tissue (fat). Intracellular fluid is 40% of body weight, and extracellular fluid is 20% of body weight (60-40-20 rule).
Example Question #3 : Help With Other Excretory Physiology
What are the major cations of intracellular fluid?
Proteins and organic phosphates
Intracellular fluid (ICF) is two-thirds of total body water. Its major cations are 
Example Question #4 : Help With Other Excretory Physiology
Extracellular fluid contains which cations and anions?
Proteins and organic phosphates
Extracellular fluid (ECF) contains the cation 
Intracellular fluid (ICF) provides two-thirds of TBW. Its major cations are
