Respiratory System

During ________________________, cells use _____________ to release theenergy stored in __________________. To do this, the __________________________________ supplies oxygen and removes ___________ ______________.This is called ________ exchange.

The difference between respiration (also called _____________ ____________ )and breathing (sometimes called ________________) is:Respiration is the process of releasing _____________ from ______________ in thecells. This takes place in the _____________________ of the cells. Breathing is theprocess of moving ________ into and out of the ______________. Breathing isnecessary to supply ____________ (from the air) to the cells for __________________.

The formula for chemical reaction in respiration is:__________ + ___________ ______________ + ____________ + ____________.This can also be represented as:__________ + ___________ ______________ + ____________ + ____________.
