composed of only ONE cell unicellular composed of only ONE cell

composed of several or many cell multicellular composed of several or many cell

transport system a system of tubes with a pump and valves to ensure one way blood flow. We need a transport system to deliver oxygen, nutrients and other substances to all our body cells, and take away waste products from them.

Circulatory / Cardiovascular System Supplies the body with blood, nutrients, and O2 through a systems of vessels; works with many systems

heart Function: Pumps blood through the body over and over again 
Systems: Circulatory

Blood vessels a tubular structure carrying blood through the tissues and organs; a vein, artery, or capillary

Respiratory System Breathing- Movement of chest to bring fresh air in and "waste" air out. Supplies O2 and removes CO2

Function: Letting of the air flow into the lungs System: Respiratory trachea Function: Letting of the air flow into the lungs
System: Respiratory

lungs Function: The primary function of the lungs is respiration. They enable you to breathe and bring oxygen into the body and carry out carbon dioxide.
System: Respiratory, Excretory

Skeletal System Gives shape and support to the body; protects organs; produces red blood cells

bones any of the pieces of hard, whitish tissue making up the skeleton in humans and other vertebrates

Muscular System Makes all movement possible from moving skeletal muscles (walking, running, etc) to digestion (smooth muscle)

muscles a band or bundle of fibrous tissue in a human or animal body that has the ability to contract, producing movement in or maintaining the position of parts of the body

Digestive System Breaks down food into small molecules so that they can be absorbed and moved into the blood. Removes solid wastes. 2 Types- mechanical & chemical

the opening through which food is taken in and vocalizations emerge mouth the opening through which food is taken in and vocalizations emerge

esophagus When a person swallows, the muscular walls of the esophagus contract to push food down into the stomach

stomach the internal organ in which the major part of the digestion of food occur

Nervous System Allows the body to sense and respond to its environment; helps maintain homeostasis

portion of the digestive tract extending from the stomach to the anus intestines portion of the digestive tract extending from the stomach to the anus
