I am doing a science essay on this at school and need help
okay do you mean cycle of breathing and stuff look:
You probably breathe about 20 times every minute. If you are running or playing hard, you might take 80 breaths a minute.
When you inhale air through your nose or your mouth, that air takes off on an incredible journey. First it goes down the back of your throat, past your voice box, and into your windpipe, or trachea. Your trachea is like a tunnel that branches off into two more tunnels called BRONCHIAL tubes or BRONCHI. Each bronchial tube goes off to one of your lungs. It doesn’t matter whether the air goes to the right lung or the left lung. Both lungs do the same job...Inside your lungs, the bronchi are like upside-down trees. They split into smaller and smaller branches and then into many twigs. The twigs end in tiny air sacs called alveoli. So far, the air has just been along for the ride. Inside the alveoli the air really goes to work. Its job is to keep us ALIVE!
The job of the air in your alveoli is to bring oxygen into your body and take carbon dioxide out. Oxygen and carbon dioxide are two invisible gases in air. The secret to doing this job is BLOOD .The air in your alveoli sends oxygen into your blood. Your blood flows through a system of tubes called blood vessels. First, blood full of oxygen goes to your heart. Your heart is like a big pump. It sends the oxygen-filled blood whooshing off to all parts of your body.
The blood vessels that deliver oxygen are called arteries. Arteries branch off into smaller and smaller tubes. The tiniest blood vessels are called capillaries. Capillaries reach every cell in your body and drop off the oxygen. In your cells, the oxygen works with food to make energy for you.
P.S: I am sorry I just know this!!!
it's first stop is your lungs. then from there your blood absorbs it through a thin membrane. now that it's in your blood cells it travels all through your body and is deposited throughout. it your muscles it keeps the cells alive and helps neutralize the lactic acid that builds up when your muscles work. hope this helped. if you need more detail just ask:)
thanks zvbvi3j9 thats exactly what I need but wow I hop it wasn't to much trouble to get that information.
I really appreciate your help
thank you soooo much i reli needed this for a assesment due monday morning THANKYOU SOOOO MUCHHHH
OMG! I needed this for a science project! thanks sooo much, you are a LIFE SAVER!
isnt it resperation?
