How are lymphatic capillaries related to the function of the lymphatic system?
A) The wall of the lymphatic capillary consists of a multiple layer of flattened endothelial cells that prevents drainage of blood into the lymphatic system.
B) The lymphatic capillary network allows lymph to flow from the larger-walled capillaries into the vessels with a thin wall diameter.
C) The high degree of permeability of the lymphatic capillary wall permits very large molecules and even particulate matter, which cannot be absorbed into the blood capillary, to be removed from the interstitial space.
D) The thoracic duct is approximately the same size as the large veins and forms an open circuit to drain fluid into the renal system.

Question

Lymphatic capillaries have a highly permeable wall that allows for the removal of large molecules and particulate matter that cannot be absorbed by blood capillaries. This process helps to maintain fluid balance in the body and prevent edema (swelling).
