Four body systems we studied
What are the circulatory, respiratory, excretory, and digestive systems
If water molecules pass from a jar of water and into an egg with no shell, we say the molecules have moved into an area of...
What is an area of lower concentration
Blood travels away from the heart in these
Whare are arteries
Diffusion is...
The movement of molecules from an area of high concentration to an area of low concentration.
The two types of digestion
What are mechanical and chemical digestion
Osmosis is...
The diffusion of water molecules from an area of high concentration to low concentration
The main organs involved in the excretory system
What are the skin, lungs, kidneys, bladder, ureters, and liver
The result of diffusion
What is equilibrium
What organs do the respiratory system use (in the order that air travels)
What are the nose, trachea, bronchi, lungs, bronchioles, and alveoli
