This histological image shows a small artery and vein within connective tissue, stained with hematoxylin and eosin (H&E). The artery, located on the lower right, has a thick tunica media composed of smooth muscle, maintaining a round shape. The vein, in the upper left, has a thinner wall and a more irregular, collapsed appearance. The surrounding tissue consists of adipose cells, which appear as large, white, empty spaces due to the lipid removal during tissue processing. The staining highlights the structural differences between arterial and venous walls, emphasizing the artery’s muscular layer and the vein’s relatively thinner composition.
