'Appetites' in the Bible

When we were living in the flesh [trapped by sin], the sinful passions, which were awakened by [that which] the Law [identifies as sin], were at work in our body to bear fruit for death [since the willingness to sin led to death and separation from God].

but I see a different law and rule of action in the members of my body [in its appetites and desires], waging war against the law of my mind and subduing me and making me a prisoner of the law of sin which is within my members.

and those who are in the flesh [living a life that caters to sinful appetites and impulses] cannot please God.

For such people do not serve our Lord Christ, but their own appetites and base desires. By smooth and flattering speech they deceive the hearts of the unsuspecting [the innocent and the naive].
