in the absence of a lymphatic system, if hydrostatic pressure in a blood capillary exceeds its oncotic pressure, what will happen?
○ fluid will accumulate/ increase in the capillary.
○ none of the fluid will enter lymphatic capillaries because lymphatic capillaries are impermeable to water.
○ fluid will accumulate/ increase in the plasma
○ fluid will accumulate/increase in the interstitial space.

Explanation:

To solve this, we analyze capillary fluid dynamics. Hydrostatic pressure pushes fluid out of capillaries, oncotic pressure pulls it back. If hydrostatic > oncotic (and no lymphatic system to return excess), fluid moves into interstitial space (between cells/tissues). Other options are incorrect: fluid doesn't stay in capillary (hydrostatic pushes out), lymphatic capillaries are permeable to water, and fluid doesn't accumulate in plasma (oncotic pressure would pull fluid back, but hydrostatic is higher here, so fluid exits plasma into interstitial space).

Answer:

Fluid will accumulate/increase in the interstitial space.
