Why Is It Easier for Cancer Cells Present in the Interstitial

Why is it easier for cancer cells present in the interstitial fluid to enter a lymphatic capillary than a blood capillary?

A) Unlike lymphatic capillary walls, blood capillary walls are lined with smooth muscle cells that prevent the entry of foreign substances.
B) Unlike blood capillaries, lymphatic capillaries have overlapping ends that facilitate easier passage for interstitial fluid.
C) Lymphatic capillaries have thinner walls than blood capillaries.
D) The endothelial cells lining the lymphatic capillary walls facilitate quicker transcytosis of substances than blood capillaries.
E) The spaces between the endothelial cells of lymphatic capillaries are larger than the pores of blood capillaries.
