Solution: The ends of the endothelial cells in the wall of the lymphatic capillary overlap. When pressure is higher in the interstitial fluid than in the lymph, the cells separate slightly allowing interstitial fluid into the vessel. When pressure is greater inside, the cells are tightly packed, not allowing the lymph to cross back into the interstitial fluid.

Difficulty: Medium
Study Objective 1: SO 22.6 Understand the components and functions of the antibody-mediated immune response.
Study Objective 2: SO 22.6.4 Distinguish between a primary response and a secondary response to infection.
Answer: Naturally acquired active immunity is acquired following exposure to a microbe, antigen recognition by B and T cells and costimulation leading to formation of antibody-secreting plasma cells, cytotoxic T cells, and B and T memory cells. Naturally acquired passive immunity occurs when IgG antibodies are transferred from mother to fetus across the placental barrier or IgA antibodies are transferred from mother to infant during breast-feeding. Artificially acquired active immunity is acquired via antigens introduced during vaccinations. Artificially acquired passive immunity is acquired via intravenous injection of immunoglobulins.
