[VII C $4 \mathrm{c}$; Table 3.2]. Edema occurs when more fluid is filtered out of the capillaries than can be returned to the circulation by the lymphatics. Filtration is increased by changes that increase $\mathrm{P}_{\mathrm{c}}$ or decrease $\pi_{\mathrm{c}}$. Arteriolar constriction would decrease $\mathrm{P}_{\mathrm{c}}$ and decrease filtration. Dehydration would increase plasma protein concentration (by hemoconcentration) and thereby increase $\pi_{\mathrm{c}}$ and decrease filtration. Increased venous pressure would increase $\mathrm{P}_{\mathrm{c}}$ and filtration.
