Oxygen makes up about 65% of the human body by mass.
Each human body has a different about of oxygen in it. A male weighing about 148 pounds has 65% oxygen.
65%
because without oxygen you cant breathe.
Oxygen is essential for cellular respiration, a process that generates energy for the body. It is needed to produce ATP, the energy currency of cells, allowing them to function properly. Oxygen also plays a crucial role in the immune system, helps in the detoxification process, and supports overall brain function.
On average, the human body is composed of about 65% oxygen by mass, primarily in the form of water (H2O) and other organic molecules. This oxygen is essential for cellular respiration, which is the process by which cells generate energy.
The heart is responsible for circulating blood through the body, and the lungs are responsible for oxygenating it. Both are needed to get the much needed oxygen to the cells of the body.
The average adult human body contains about 3-4 grams of iron. It is an essential mineral that is important for the production of red blood cells and transporting oxygen in the body.
The human body needs approximately 550 liters of oxygen per day to sustain normal function. This oxygen is utilized in various physiological processes including respiration, metabolism, and energy production.
Send blood to all the cells of the body; bringing nourishment and removing waste. They also bring much needed oxygen to the body from the lungs.
lool well oxygen is pretty much needed for life. oxygen is used for oxidation purposes in our metabolism to synthesise ATP (energy), that's why you breathe it in. Without oxygen, you woudlnt be alive.
It makes the red blood cell much better at carrying oxygen!! It can absob oxygen easily and doesn't "leak" oxygen as the blood travels to the body tissues where the oxygen is needed!
