The lungs are the organ that takes air into the body. The air is taken in through the nose and the mouth.
Organisms obtain energy from their food through oxidative metabolism. Sugars are broken down to water and carbon dioxide and that requires oxygen. Humans extract oxygen from the air via their lungs so that the exhaled air has less oxygen (and also more carbon dioxide) than ambient air.
because they both contain air
The nose is one of the primary entry points for respiration. The air gets in your nose and goes down the trachea. Your lungs take in oxygen and pass it around the body. The arteries carry the oxygen away and the veins carry the deoxygenated blood in.
Respire. This is a dictionary definition, often used in crosswords. I do not believe it is the same as the other interpretation being touted as meaning the same
as when we take air( o2) ,the broncheol(have a special type of skin which take the o2 thru blod flow for all cells present in human body),so mainly the respiratory system linked to circulartory system to provide o2 to cells of the body.
air contains oxygen the body needs
no
Your body takes in air through your nose and mouth. There is another interpretation of the original question. "to respire"
Your nose and mouth.
The lungs take in oxygen directly from the air.
the veins in your body take air from your nose into the lungs
It comes through your nose and into your lungs through the trachea.
Yes. You take in air which is about 20% oxygen
External nostrils are the parts of our respiratory system which help in the exchange of gases between your body and surrounding air.
When our body is in relaxed state, it will probably take up quarter of a liter air every time we breathe in. When our body is engaged in some activity, the amount of air taken in increases. A professional bike racer's amount of air taken in can reach up to 2 liters.
