What do cells need?

What do cells need?. External Environment. Internal environment. -needs to be highly regulated This is done by receiving information in the form of signals and responding to these signals - Homeostasis is the process of maintaining a relatively stable internal environment.

Fentanyl Citrate

Fentanyl Citrate. Narcotic agonist/narcotic analgesic. Mechanism of Action:. Alleviates pain by acting on the pain receptors in the brain; elevates pain threshold. Depresses central nervous system; depresses brainstem respiratory centers; decreases responsiveness to changes in PaC02.
