Answer:
The correct answer is 6.67 %.
Explanation:
The average osmotic pressure of the brain is 300 mM
Given the concentration of solution is 280 mM
Difference is 300 - 280 = 20 mM
This difference is sufficient to stimulate osmosis and make water move from CSF to the brain until the concentration becomes similar.
Also, it is known that the volume of brain is about 1200 ml on an average,
Volume of fluid moved because of osmosis = 20 mM / 300 mM * 1200 ml = 80 ml
Percent swelling of brain = 80 ml / 1200 ml * 100 = 6.67 %
Answer:Chyme is the name given to the partially digested food mass. The pyloric sphincter is a tight valve, and, therefore, very little chyme is allowed to exit the stomach at one time.
