 the circulatory system

This is where the red blood cells pick up oxygen from the lungs as the red blood cells contain hemoglobin which turns to oxyhemaglobin when the oxygen is picked up. this then gets transported throught the LEFT side of the heart. Then it gets taken throughout the body and the oxygen gets used up in which ever muscles need it most, the deoxygenated blood then gose throught the RIGHT side of the heart and back to the lungs to pick up more oxygen.

*the circulatory system is a cycle, in an exam it doesnt matter which part of the cycle you start at as long as you explain the full cycle.
