No we would have been filthy rich if that happened
Quartz consists of silicon and oxygen (2 times as many oxygen atoms than silicon atoms).
the quality of our blood that rich with oxygen will become low
The left atrium receives oxygen-rich blood.
Dark red blood is oxygen-poor. Bright red blood is oxygen-rich.
Oxygen rich - the opposite of what the majority of veins are in the body.
blood coming from the HEART is rich in oxygen
By definition, ALL arteries carry Oxygen rich blood. Veins carry oxygen depleted blood.
'c' heart pumps oxygen rich blood, 'a' oxygen rich blood arrives at capillaries, 'd' oxygen moves through capillary walls, 'b' oxygen enters body cells.
OXYGEN
Oxygen rich air enters the body through the lungs.
All arteries except the pulmonary artery transport oxygen-rich blood
Blood entering the left ventricle is rich in oxygen. In contrast, oxygen-poor blood enters the right ventricle.
If the oxygen-rich blood and the oxygen poor blood mix the amount of oxygen becomes diluted. The cells and tissues need more oxygen than they will get.
