What happens to the excess fluid that leaves the capillaries at the venous end?Multiple ChoiceThe excess fluid is collected in the lymphatic capillaries.There is no excess fluid; 100% always returns to the capillary beds.The excess fluid is excreted by the kidneys.The excess fluid is reabsorbed by the intestines.The excess fluid will accumulate in the cells, causing them to rupture.

Excess tissue fluid becomes lymphatic fluid that eventually enters the bloodstream.Group startsTrue or FalseTrue, unselectedFalse, unselected

What happens to lymph as it passes through a lymph node?Multiple choice question.The lymph is reabsorbed into the bloodstream.Any red blood cells are destroyed.Any debris or pathogens are engulfed by macrophages.Histamine is released into the lymph.

Why does fluid leave capillaries at their arteriolar end and enter at the venular end?Multiple ChoiceHydrostatic pressure is lower than osmotic pressure at the arteriolar end and higher at the venular end.Hydrostatic pressure is higher than osmotic pressure at the arteriolar end and lower at the venular end.

[2](ii) Describe the role of the lymphatic vessel shown in Fig. 1.1.[2](c) Lacteals are another part of the lymphatic system.State where in the body lacteals are found and state their function. [2](d) In the lymphatic system, there are structures that contain large numbers oflymphocytes.(i) State the name of these structures.[1](ii) State the role of lymphocytes.[2]

Which of the following is not a main function of the lymphatic system? A. Lymphatic capillaries absorb carbohydrates and transport them to the bloodstream B. Lymphatic system is responsible for the production, maintenance, and distribution of lymphocytes C. Lymphatic system helps defend the body against pathogens D. Lymphatic capillaries absorb excess tissue fluid and return it to the bloodstream
