Oxygen saturation is a term referring to the fraction of oxygen-saturated hemoglobin relative to total hemoglobin (unsaturated + saturated) in the blood. The human body requires and regulates a very precise and specific balance of oxygen in the blood. Normal blood oxygen levels in humans are considered 95-100 percent.If the level is below 90 percent, it is considered low resulting in hypoxemia. Blood oxygen levels below 80 percent may compromise organ function, such as the brain and heart, and should be promptly addressed.Continued low oxygen levels may lead to respiratory or cardiac arrest.he needs of the body's blood oxygen may fluctuate such as during exercise when more oxygen is required or when living at higher altitudes. A blood cell is said to be saturated when carrying a normal amount of oxygen. Both too high and too low levels can have adverse effects on the body.
Inner transition metal. An inner transition metal (ITM) is one of a group of chemical elements on the periodic table. They are normally shown in two rows below all the other elements. They include elements 57-71 (lanthanides) and 89-103 (actinides). The lanthanides are very similar, and the actinides are all radioactive.
Best Answer: In the electron config. , show that the phosphorus has 15 electrons when it is in neutral state. The outermost shell has 5 electrons. Therefore, the inner-shell have 10 electrons. Reason: 1s2 - first orbital 2s2 2p6 - second orbital 3s2 3p3 - third orbital so, third orbital is the outermost shell and it has 2+3=5, 5 electrons in this shell. Inner-shells are the shells that contains in atom, except the outermost shell.
