Lymph Node Anatomy: Structure and Function Explained #3324665 (License: Personal Use)

This diagram depicts a lymph node’s internal architecture, including afferent lymphatic vessels entering at the capsule, cortical follicles with germinal centers, paracortex rich in T cells, and medullary cords draining into the efferent vessel. The reticular fiber network supports immune cell trafficking and antigen presentation. Blue arrows indicate lymph flow direction, highlighting unidirectional filtration and immune activation.

Used in medical education, immunology textbooks, and health websites to explain lymphatic system function; targets students, clinicians, and patients seeking to understand immune defense mechanisms.
