What is a blood vessel?
Which side has the highest concentration of molecules?
A B
What is side A has the highest concentration of molecules?
The organ system that carries messages between the brain and the body.
(Vocabulary Choices: Homeostasis, Nervous System, Stimulus, Response, Neuron)
What is the Nervous System?
When molecules move from an area of higher concentration to an area of lower concentration.
(Vocabulary Choices: Concentration, Passive Transport, Diffusion, Active Transport)
What is diffusion?
The location of gas exchange in the lungs
(Vocabulary Choices: Exchange, Alveoli, Respiratory System)
What is alveoli?
