The study of the structure of body parts and their relationships to one another.

The study of the functions of body parts and how they work together to maintain life.

The body’s ability to maintain a stable internal environment despite changes in the external environment.

A control mechanism that reverses a change in a controlled condition to restore homeostasis (e.g., body temperature regulation).

A mechanism that strengthens or reinforces a change until an endpoint is reached (e.g., childbirth or blood clotting).

A selectively permeable barrier that controls what enters and leaves the cell.

Organelles that produce ATP, the cell’s main energy source, through cellular respiration.

Small organelles responsible for protein synthesis.

A group of similar cells that perform a specific function.

Covers body surfaces, lines cavities, and forms glands.

Supports, protects, and binds other tissues (includes bone, blood, and cartilage).

Specialized to contract and produce movement; types include skeletal, cardiac, and smooth.

Composed of neurons and neuroglia; functions in communication and control of body activities.

Consists of skin, hair, nails, and glands; protects the body, helps regulate temperature, and detects sensations.

The middle layer of skin that contains connective tissue, blood vessels, and sensory receptors.
