Anatomy

The branch of science that studies the structure of organisms, including their systems, organs, and tissues.

Physiology

The branch of biology that focuses on the functions and processes of living organisms and their parts.

Chemical Level

The most basic level of organization, involving atoms and molecules that form the building blocks of matter.

Cellular Level

The level at which cells are formed from molecules; cells are the basic unit of life.

Tissue Level

Groups of similar cells that come together to form tissues, which perform specific functions.

Four primary tissue types

Epithelial, connective, muscle, and nervous tissue.

Organ Level

A level of organization where different types of tissues combine to form organs.

Organ System Level

Groups of organs that work together to perform complex functions.

Examples of Organ Systems

Circulatory system, respiratory system, and digestive system.

Organism Level

The highest level of organization, where all systems work together to sustain life within a single organism.

Tissues

Groups of similar cells that come together to perform specific functions.

Organs

Structures made up of different types of tissues that combine to perform more complex functions.
