Nose – Your nose plays a key role in your sense of taste. You may remember that the last time you had a cold, nothing tasted quite right. That was because your nose was all stopped up. When you eat, vapors from your food float up through the back of your throat and into your nose. Then your nose reports what it smells to your brain. Your brain must have information from both the taste buds on your tongue and the sensors in your nose to tell how something really tastes. Lungs – your lungs inhale (breathe in) and exhale (breathe out) about 12 to 20 times a minute when you are at rest. Each time you inhale fresh air into your lungs; the blood in your circulatory system picks up oxygen and drops off carbon dioxide. The carbon dioxide is pushed out of your lungs when you exhale. Blood that is loaded with oxygen is bright red. The iron in your blood holds onto the oxygen until it can be delivered to your muscles or another part of your body that needs it. After delivering oxygen and picking up carbon dioxide to take back to your lungs, your blood turns blue. When you skin your knee or bleed for some other reason, the blood that comes out is red because it comes into contact with the oxygen in air outside of your body
