Written in 1641, the ''Apologia pro circulatione sanguinis'', Ent’s most significant work on [[anatomy]], defends the theories of [[William Harvey]]’s book ''[[Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus|de Motus Cordis]]'' (''On the Circulation of the Blood''), directly responding to the criticism of [[Emilius Parisianus]]. This book is significant both on the merits of Ent's own anatomical theories and because it offered one of the first in-depth defenses of Harvey’s work.
In the ''Apologia'', Ent elaborates on Harvey’s theories on [[circulation]], suggesting that a “nutritive fluid” nourishes the body by passing through the nerves. Ent draws on [[John Mayow]]’s theories on [[innate heat]] and [[respiration]] in his discussion of the [[nervous system]]. In addition to Harvey’s work, Ent references both ancient and contemporary sources, particularly mentioning writers discussing topics now considered occult, whom Harvey dismissed.
