This body system is responsible for the breakdown and absorption of food.

Digestive System

This level consists of all of the body systems combined.

What is homeostasis and how is it maintained in the body?

Homeostasis is the condition in which the body's internal environment remains relatively constant, within physiological limits.  It is maintained via feedback systems.

Cervical region is commonly known as?

Neck

200

This body system is made up of the brain, spinal cord, and nerves.

Nervous system

200

This Life Process is the process of unspecialized cells undergo to become specialized cells.

Differentiation

What is the role of a control center in a feedback system?

A control center receives the input, compares it to a set of values that the controlled condition should have and send output commands to an effector

Thoracic region is commonly known as?

chest

300

This body system delivers oxygen and nutrients to all cells and tissues, while removing carbon dioxide and wastes.

Cardiovascular system

300

This level of organization contains atoms, the smallest units of matter.  Common atoms in living things include carbon, hydrogen, oxygen, nitrogen, and phosphorus.

Chemical

Describe the difference of a negative feedback system and a positive feedback system.

A negative feedback system tries to reverse a change to reestablish homeostasis.

A positive feedback system tries to increase or enhance a change that has occured in the body, until the triggering stimulus has ended.

300

Toward the surface of the body.

Superficial

300

Dorsal region is commonly known as?

Back
400
Some of this body systems secondary functions are to produce blood cells and store minterals.

Skeletal system

400

This Life Process includes motion of the whole body, individual organs, single cells, and every tiny structure inside cells.

Movement

What is an effector?  Give an example of an effector and how it could respond to the control center.

An effector receives output commands and produces a response that changes the controlled condition.

Away from the point of attachment

Distal

Crural region is commonly known as?

calf or lower leg

500

This body system is made up of skin, hair, and nails and provides an outer covering that protects the internal systems.

Integumentary system

500

This is an  increase in size due to an increase in the size of existing cells, the number of cells, or the amount of material surrounding cells.

Growth

Pick a controlled condition and writing out in simple terms how a negative feedback loop maintains homeostasis.
