A cockroach has six legs because it makes their sense of smell extremely high due to the tiny sensory hairs on each leg.

Organ System Structure Function Relationship

# data[].attributes.body
The nervous system in the cockroach contains the brain, spinal cord, and eyes. The cockroach's eye contains more than a thousand lenses which allows it to see multiple things at once.

# data[].attributes.body
The cockroach has stratified squamous (skin) to protect itself from danger and things getting in it's body.

# data[].attributes.body
The cockroach has muscle tissues that are strong, allowing the cockroach to walk and move it's legs.

# data[].attributes.body
The cockroach contains erythrocytes (red blood cells) to provide oxygen. When the cockroach was put into the ice water it's erythrocytes were in action allowing it to hold it's breath for a long period of time.

# data[].attributes.body
The cockroach has Na+ ions to go into the cell. It's small enough to fit in the gates unlike protein. Na+ ions help balance out the cell with K+ ions.

# data[].attributes.body
When one of the cockroach's legs are removed then homeostasis becomes out of balance. Blood clotting occurs and allows the cockroach to survive. Homeostasis will become maintained again once the leg grows back.

# data[].attributes.body
Homeostasis is maintained when the cockroach has all six of it's legs because internally it is at equilibrium.

# data[].attributes.body
Impulses are sent to the brain of the cockroach to allow movement to occur in the leg.

# data[].attributes.body
The cockroach was the living individual.

# data[].attributes.body
The cockroach's skin has stratified squamous.

# data[].attributes.body
In order for the leg to move, the cockroach needs it's muscle tissue.

# data[].attributes.body
The cockroach has erythrocytes (red blood cells) that transports oxygen and carbon dioxide to and from the tissues.

1.) Chemical - atoms: smallest units of matter that participate in chemical equations, molecules: 2 or more atoms joined together
2.) Cellular - cells are basic unit of life, all types, sizes and functions
3.) Tissue - groups of similar cells with a common function, 4 types of tissues (epithelial, connective, muscle and nervous)
4.) Organ - composed of 2 or more types of tissues with specific nutrition
5.) Organ System - related organs that have a common function, one organ may be part of more than one system
6.) Organism - the living individual

Superior - towards the top or the sky (above)
Inferior - towards the ground (below)
Proximal - nearer to the point of reference
Distal - located far from a point of reference
Posterior - to the back of the body
Anterior - to the front of the body
Medial - inner toward the body (middle)
Lateral - outer side of the body
Transverse Plane - divides the body of superior and inferior parts (top and bottom)
Sagittal Plane - divides the body into left and right parts
Frontal Plane - vertical plane that divides the body into ventral and dorsal (belly and back) sections

# data[].attributes.body
Homeostasis - the body maintains a stable equilibrium internally
Maintained: the cockroach has all six of it's legs
Out of Balance: the cockroach has at least one leg missing
