Lymph enters a lymph capillary by

Question

Quizplus · Accepted Answer

Lymph capillaries are designed to be highly permeable to allow for the entry of interstitial fluid, which contains lymphocytes and other immune cells. The pressure from the accumulation of fluid within the interstitial space forces the fluid between the cells of the lymph vessel wall and into the lumen of the capillary. Once inside, the lymph is propelled further through the lymphatic system by the contraction of smooth muscles in the vessel walls and skeletal muscle contractions.
