Flashcards

Bone Marrow

Produces red blood cells (RBCs), white blood cells (WBCs), and platelets, which are essential for blood clotting and immune responses.

Thymus Gland

Site of T-cell maturation, where these immune cells learn to distinguish between self and non-self cells.

Spleen

Filters lymph, stores lymphocytes (special WBCs), and removes old or damaged red blood cells.

Lymph Nodes

Small, bean-shaped organs located along lymphatic vessels, filtering lymph fluid for pathogens.
