The pulse oximeter is able to function despite the absorbance of nonblood tissues, because it uses IR light (which is absorbed by all tissues equally) as a baseline.
An average diet contains 1,200 mg of calcium, one-third of which is absorbed.
An example of a systemic toxicant is methanol, which is absorbed and biotransformed into formic acid.

The Scramscreen's alternating rows of clear and black polymers reduce ambient light, which is absorbed by the black rows, increasing the effective contrast.

The study measured the ratio of calcium, a basic building block of teeth and bones, to strontium 90, which is absorbed just as calcium is.
The increase in carbon dioxide pumped into the atmosphere, 90% of which is absorbed by the oceans, has already caused a 30% rise in the hydrogen ions that cause ocean acidification.
