Front 8

Organ System

Back 8

A group of organs that together perform a function that helps the body meet its needs for energy and materials.

Front 9

Homeostasis

Back 9

The ability of your body to maintain internal conditions such as your body temperature, amount sugar in the blood and posture.

Front 10

Skeletal System

Back 10

Serves as the anchor for all body's movement, provides support and protects soft organs inside the body.

Front 12

Spongy Bone

Back 12

The soft, inner layer of the bone

Front 13

Axial Skeleton

Back 13

Provides support and protection to the body. Includes the skull, ribs and spinal column (vertebrae).

Appendicular Skeleton

Back 14

Function mainly to allow movement. Includes all other areas of the skeleton not included in axial, including arms, legs, shoulders, etc.

Front 15

Muscular system

Back 15

Works with skeletal system to allow movement. Also helps to maintain body temperature and posture.

Front 16

Exchanging oxygen and carbon dioxide AND Cellular Respiration

Front 20

Nutrient

Back 20

Important substances that enable the body to move, grow and maintain homeostasis.

Front 21

Respiratory system

Back 21

The body system that functions to get oxygen from the environment and remove carbon dioxide and other waste products form the body.

Front 22

Digestion

Back 22

The process of breaking down food into usable materials in the body.

Front 23

Digestive system

Back 23

An organ system that performs complex jobs of moving and breaking down food into usable materials for the body. Organs in the digestive system include mouth, throat, stomach, intestines.

Front 24

Peristalis

Back 24

When material is moved through the digestive system by wavelike contractions of smooth muscles.

Front 25

Circulatory system

Back 25

An organ system that transports materials from the digestive and respiratory systems to the cells.

Front 26

Blood

Back 26

Moves continuously through the body, delivering oxygen and other materials to cells and removing carbon dioxide and other wastes from cells.

Front 27

Red blood cell

Back 27

Picks up oxygen in the lungs and transports it throughout the body.

Front 28
