Which of the following pressures is necessary for lymph to be produced?
Decreased osmotic pressure
Increased hydrostatic pressure
Decreased hydrostatic pressure
increased osmotic pressure
The Correct Answer is B
a: Decreased osmotic pressure - Decreased osmotic pressure would lead to fluid retention within the capillaries, not lymph production.
b. Increased hydrostatic pressure: Lymph is produced when there is an increase in hydrostatic pressure within the capillaries, which forces fluid and solutes out into the interstitial space, forming lymph.
c: Decreased hydrostatic pressure - Decreased hydrostatic pressure would result in decreased filtration of fluid from the capillaries, hindering lymph production.
d: Increased osmotic pressure - Increased osmotic pressure would draw fluid back into the capillaries, opposing lymph formation.
