Countercurrent flow is when the flow of water over the gill lamellae is in the opposite direction to the flow of blood within the gill lamellae.
Il flusso contrapposto è quando il flusso d'acqua sulle lamelle branchiali è nella direzione opposta al flusso sanguigno all'interno delle lamelle branchiali.
