The process of building up larger molecules form smaller ones during metabolism

Anatomy

The study of the organs and systems of the body

Catabolism

The process of breaking down larger molecules or substances into smaller ones during metabolism

Cell Membrane

The outer surface of the cell, which encloses the protoplasm

Cells

The basic units of living matter (life)

Circulatory System

Controls the circulation of blood and lymph through the body

Connective Tissue

Supports, protects, and holds the body together

Contracts, when stimulated, to produce motion

Nerve Tissue

Carries messages to and from the brain and coordinates body functions

Nucleus

The control center of cell activities; the dense core of an atom that contains protons and sometimes nuetrons

Organs

Separate body structures that perform specific functions; composed of two or more different tissues

Physiology

The study of the functions that bodily organs and systems perform

Protoplasm

Gel-like substance found in cells containing water, salt, and nutrients obtained from food

Systems

Group of body structures and/or organs that together perform one or more vital functions for the body

Tissues

Groups of cells of the same kind performing a specific function in the body
