Question

Which of the following describes the order in which lymph flows to enter and leave the lymph nodes?

• A. Afferent vessels $\to$ Cortex $\to$ Medulla $\to$ Efferent vessels
• B. Cortex $\to$ Afferent vessels $\to$ Medulla $\to$ Efferent vessels
• C. Efferent vessels $\to$ Cortex $\to$ Medulla $\to$ Afferent vessels
• D. Medulla $\to$ Afferent vessels $\to$ Cortex $\to$ Efferent vessels

Answer 1

The correct option is A Afferent vessels $\to$ Cortex $\to$ Medulla $\to$ Efferent vessels

Lymph enters each node through the afferent vessels. It first enters the cortex, flows to the medulla, and departs from medulla through the efferent vessels.
