4) Describe how lymphatic capillaries are one-way only vessels.

Answer:

Difficulty: Medium

Study Objective 1: SO 22.1 Understand the various components and major functions of the lymphatic system.

Study Objective 2: SO 22.1.2 Describe the organization of lymphatic vessels.

Section Reference 1: Sec 22.1 Lymphatic System Structure and Function

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.

Question type: Multiple Choice
