Physiologists are constantly trying to answer key questions in areas
ranging from the functions of single cells to the interactions between
human populations and our environment here on earth, the moon, and beyond.
Physiologists ask questions like . . .
Why does blood clot in a wound but not while flowing through blood
vessels?
Can we prevent loss of bone mineral during space flights or
confinement to bed?
How does the nervous system convert stimuli into memories? How do we
access those memories?
What factors limit human athletic performance?
What causes new genes to be activated and expressed in failing
hearts, and how does this contribute to poor performance of these hearts
as circulatory pumps?
How does a person’s genetic inheritance predispose him or her to
certain diseases later in life?
How does a person’s gender affect his or her body’s response to
physiological or environmental stress?
How do organs repair themselves after damage due to stroke, heart
attack, or other insult?
