Marcello Malpighi used early microscopes to look closely at tissues and revealed a network of tiny vessels bridging arteries and veins. This microvascular web, the capillaries, showed how blood moves from the heart into tissues and back, making visible the microscopic connection between arterial and venous circulation. His careful observations in organs like the lungs demonstrated the capillary loops that form the crucial link in the circulatory system, tying together anatomical structure with developmental and tissue-level processes studied in embryology. That discovery solidified his place as the figure associated with uncovering capillaries.

Edward Jenner is known for pioneering vaccination, Baron Karl Wilhelm von Humboldt for his broad natural-science and exploratory work, and Jean Baptiste Denys for early transfusion experiments. None of them identified the capillary network, which is why Malpighi is the correct association.
