It goes round on its own because it's inert
When you breathe it in the oxygen runs around your body and passes through the walls into your blood stream
200000 miles an hour
It binds to red blood cells, which transport it to the tissues and organs.
It helps scientists know how much of what is needed to make for example the fuel or how much of gases they need to give the astronauts oxygen.
yes, in some ways. Helium is less dense than air (air is mainly nitrogen and oxygen) and because of this helium moves easier when a force is exerted upon it (such as a sound wave). The sound waves simply move faster in helium which causes the sound to appear higher. However, when you breath in helium and speak sound waves must travel from the helium in your breath to the air in the surrounding room. The best example of what basically happens that I have heard is that as the sound waves transfer into the more dense air the sound waves are slowed down, one at a time, like cars arriving at a car wreck (or anything else that causes traffic to reduce its speed by a good amount), the cars (just like the sound waves) become bunched together and the frequency increases.

because lots of oxygen needs to travel around
yes
200000 miles an hour
through pulmonary veins
What you need 2 travel on the moon is water, food, shelter, oxygen, and lots of other supplies example space suit
A circuit is a complete loop that things can travel around. There are electrical circuits that electrons travel around, and race car circuits around a racetrack, for example.
Humans need oxygen. However, if the travel is unmanned, no oxygen would be required.
Not immediately. Helium has many negative effects on the brain. Bubbles of helium can travel to the arteries that lead to your brain. Inhaling the gas won't kill brain cells on its own, but sucking it in can cause oxygen deprivation, which can lead to your precious brain cells slowly dying.
Oxygen travels through our bodies from inhailingair which is Oxygen
the body is working extremely hard to force blood and the oxygen in the blood around the body, so by working harder you need more oxygen to travel around your muscle's, so your heart is working harder, therefore you need more oxygen.
