Animal Organization and Homeostasis - Chapter 31

Flashcards created to help students review key vocabulary terms and definitions related to animal organization and homeostasis from Chapter 31.

Tissue

A group of similar cells combined to perform a common function.

Epithelial Tissue

Tissue that covers the body surface, protecting underlying tissues, providing sensory surfaces, and secreting materials.

Simple Epithelia

A single layer of cells that lines internal organs and major body cavities, allowing diffusion.

Stratified Epithelia

Several layers of cells thick, providing protection, as seen in the skin.

Glandular Epithelia

Found in glands, secretes hormones, sweat, milk, saliva, and digestive enzymes.

Connective Tissue

Tissue that structurally supports the body, defends against pathogens, stores, and distributes substances.

Fibrous Connective Tissue

Includes loose connective tissue, dense connective tissue, and adipose tissue.

Muscle Tissue

Provides for movement of the body, including skeletal, cardiac, and smooth muscle.

Nervous Tissue

Carries information rapidly and is composed of neurons and glial cells.

Organs

Body structures composed of several different tissues grouped together for a specific function.

Integumentary System

A group of organs including skin that works together to protect the body and regulate sensory input.

Epidermis

The top layer of skin that is 10-30 cells thick and constantly regenerates.

Dermis

Layer below the epidermis that supports it and is significantly thicker.

Subcutaneous Layer

Layer beneath the skin that consists of adipose tissue and loose connective tissue.

Adipose Tissue

Connective tissue that acts as a shock absorber and provides insulation.
