How does the circulatory system maintain homeostasis in the body?
-facilitates the exchange of oxygen and carbon dioxide throughout the body.

What is active transport?
Transport of materials across a membrane using energy (Usually transport from low concentration to high concentration...against the gradient!)
200
What is osmosis?
Transport of water across a membrane

What is the difference between hypertonic, hypotonic and isotonic?
Hypo - concentration of molecules outside the cell is greater than inside, molecules move inside and cell enlarges. Hyper concentration of molecules outside the cell is less than inside, molecules move out of cell and cell shrinks Isotonic- Concentration of molecules on inside and outside of cell is equal
