You should now be able
to:
1. Relate structure with function and identify

muscle tissue (three types), and nervous
tissue

Overview: Diverse Forms, Common
Challenges
• Anatomy is the study of the biological form of
an organism
• Physiology is the study of the biological
functions an organism performs
• The comparative study of animals reveals that
form and function are closely correlated

• In vertebrates, the space between cells is filled
with interstitial fluid, which allows for the
movement of material into and out of cells
• A complex body plan helps an animal in a
variable environment to maintain a relatively
stable internal environment

Hierarchical Organization of Body
Plans
• Most animals are composed of specialized cells
organized into tissues that have different
functions
• Tissues make up organs, which together make
up organ systems

Tissue Structure and
Function
• Different tissues have different structures that
are suited to their functions
• Tissues are classified into four main
categories: epithelial, connective, muscle, and
nervous
