Define organ. (Module 1.10B) - An organ is composed of similar cells working together to perform one or more specific functions. - An organ is the highest level of organization. - An organ is the smallest living units in the body. - An organ is the smallest stable unit of matter and can form molecules. - An organ is two or more tissues working to perform several functions

An organ is two or more tissues working to perform several functions

What is the purpose of anatomical terms? (Module 1.20D) - Anatomical terms are used because all organs that perform the same function have the same anatomical term regardless of the organism. - Anatomical terms are used because they provide continuity between organs of humans and animals. - Anatomical terms are used because they provide a standardized frame of reference for describing the human body. - Anatomical terms are used because they give hints about the function of the body part. - Anatomical terms are used because they are easier to spell and pronounce than the official standard terms.

Anatomical terms are used because they provide a standardized frame of reference for describing the human body.

While standing in the anatomical position, - back refers to anterior. - front refers to inferior. - back refers to superior. - front refers to posterior. - back refers to dorsal.

back refers to dorsal.

A cell or organ that responds to commands of the control center in negative feedback is termed a(n) - thermoregulator. - receptor. - effector. - stimulus. - control center (integration center).

effector

Because the anatomy and physiology of the body's structures are interrelated, it is often said that "form determines ________." - structure - biology - physiology - anatomy - function

function

The maintenance of a constant internal environment in an organism is termed - effector control. - negative feedback. - integration. - positive feedback. - homeostasis.

homeostasis
