Some of Malpighi's notable works include "De Pulmonibus" (On the Lungs), where he described the structure of the lungs and the presence of alveoli. In "De Renibus" (On the Kidneys), he detailed the anatomy of the kidney and the presence of what are now known as Malpighian corpuscles. His work "De Externo Tactu" explored the structure of the skin and its sensory functions.
