Introduction to Human Anatomy and Physiology: Thermoregulation and Levels of Organization

Vocabulary flashcards covering body temperature homeostatic regulation and biological levels of organization based on Chapter 1.

Set Point for Body Temperature

The normal body temperature baseline of $37^\circ\text{C}$ ($98.6^\circ\text{F}$) regulated by a homeostatic mechanism.

Thermoreceptors

Sensory receptors that detect body temperature deviations and send signals to the brain's control center.

Atoms

Invisible particles that make up chemicals and join together to form molecules.

Macromolecules

Larger molecules formed by small molecules combining in complex ways, such as proteins, carbohydrates, lipids, and nucleic acids.

Cell

The microscopic basic unit of structure and function within humans and other organisms.

Organelles

Structures contained within cells of humans and complex organisms that carry out specific activities, composed of aggregates of macromolecules.

Tissue

A group of cells organized into layers or masses that have common functions.

Organs

Complex structures with specialized functions formed by groups of different tissues that interact.

Organ Systems

Groups of organs that function closely together to comprise an organism.

Organism

An individual living entity made up of interacting organ systems.
