Breathing and Respiration System

Breathing is ....

• the exchange between oxygen and ATP in the lungs

• The gas exchange between oxygen and carbon dioxide in the lungs

• The oxidation of food to release energy

• The oxidation of food to get oxygen

Cellular Respiration ....

• happens in the lung

• happens in the nose

• happens in all body cells

• happens in the blood cells

Cellular respiration is conducted ....

• in the mitochondria of muscle cells

• requiring glucose and oxygen molecules

• could be aerobic and anaerobic

• in the nucleus of body cells

Anaerobic respiration is conducted ...

• when the muscle cells get insufficient Oxygen molecules

• when the muscle cells need to produce a huge energy

• in limited oxygen producing less energy

• in limited oxygen producing lactic acids

After intensive activities, usually we will breathe faster. This is because ...

• the anaerobic respiration is shifted to aerobic respiration

• the body cells need to release out more carbon dioxide resulted from the respiration before

• the body cells need to get more oxygen to undergo aerobic respiration

• the body cells need to shift the respiration to anaerobic way
