ventricle of the heart
colombo made several important advances in anatomy, including the discovery of the pulmonary circuit which paved the way for william harvey's discovery of circulation years later. in the galenic tradition, blood passed between the ventricles of the heart through micropores in the heart's septum and venous blood became arterial blood in the left ventricle of the heart where air was supplied by the pulmonary vein. during vivisections of dogs and other animals, colombo repeatedly found only blood, and no air, in the pulmonary vein. in his model, venous blood travelled from the heart to the lungs where it was mixed with air and then returned to the heart. the permeability of the septum was questioned by michael servetus in "christianismi restitutio" in 1553 and by ibn al-nafis in the 13th century and both proposed that the blood was pushed from the right ventricle to the left via the lungs, however, both of these accounts were largely forgotten. colombo was the first to propose the pulmonary circuit in an intellectual climate that could expand on his theory. in addition to the pulmonary circuit, colombo also discovered that the main action of the heart was contraction, rather than dilation as had previously been thought. both of these discoveries were later confirmed by william harvey.

because there is little if any effective contraction of the atria there is stasis (pooling) of blood in the atria. stasis of blood in susceptible individuals can lead to the formation of a thrombus (blood clot) within the heart. a thrombus is most likely to form in the atrial appendages. a blood clot in the left atrial appendage is particularly important as the left side of the heart supplies blood to the entire body through the arteries. thus, any thrombus material that dislodges from this side of the heart can embolize (break off and travel) to the brain's arteries, with the potentially devastating consequence of a stroke. thrombus material can, of course, embolize to any other portion of the body, though usually with a less severe outcome.
