Textbook Question
Chapter 16, Problem 10CT
The cross-sectional area of the afferent lymphatic vessels arriving at a lymph node is greater than the cross-sectional area of the efferent lymphatics exiting the lymph node. The result is that lymph moves slowly through a lymph node. Why is this advantageous?

Asap Lymph enters a lymph node via afferent vessels, circulates through lymph sinuses, and then exits via efferent vessels. What is the physiological significance of each lymph node having fewer efferent vessels than afferent vessels?
What is the benefit of having fewer efferent than afferent lymphatics in lymph nodes?
Provide a brief description of the lymphatic system. What are its principal functions? Why is movement of lymph through the lym-phatic system very slow?
